What is Systematic Theology?

Click for Notes

Today’s conversation introduces the study of Systematic Theology, in the context of other forms of theology.  In particular, we recommend the course at PursueGod called Sys Theo, which introduces 12 broad topics that cover the essentials of systematic theology from a biblical perspective. This episode seeks to answer the basic question of…

What Is Systematic Theology?

Systematic theology is a discipline within Christian theology that seeks to organize and present the beliefs and doctrines of the Christian faith in a systematic and coherent way. Here are four key aspects of systematic theology:

  • Doctrinal Organization: The Bible is organized around the central story of God’s redemption, not around a list of topics or categories. Systematic Theology seeks to gather truth from the entire story of the Bible and organize it into thoughtful and consistent categories for reflection and study. Here are some of the typical categories of doctrine and their fancy names:
  • Theology Proper: This category deals with the study of God Himself. It includes discussions about the nature and attributes of God, such as His omniscience, omnipotence, omnibenevolence, and transcendence. [Note: includes a discussion of God’s mission / purpose in the world. Also: discussion of evil and suffering in the world in light of God’s nature.]
  • Bibliology: Bibliology is the study of the Bible itself. It covers topics related to the inspiration, authority, inerrancy, and interpretation of Scripture. [Note: In context of the larger question of “revelation”, of which Bibliology is a subset.]
  • Creation and Providence: These categories address the doctrine of creation, including the origin and purpose of the universe, as well as God’s ongoing providential care and governance of His creation.
  • Christology: Christology is the study of Jesus Christ. It explores His nature, including His divine and human attributes, His role as Savior, His mission, and His relationship to God the Father and the Holy Spirit. [Note: Jesus’ role as Savior is also the topic of a later category, called Soteriology.]
  • Pneumatology: Pneumatology focuses on the Holy Spirit. It examines the nature and work of the Holy Spirit in general, but particularly in the life of believers, including the Spirit’s role in regeneration, sanctification, and empowering for ministry. John 3:8 (NLT) The wind blows wherever it wants. Just as you can hear the wind but can’t tell where it comes from or where it is going, so you can’t explain how people are born of the Spirit.”
  • Anthropology: Anthropology focuses on the study of humanity. It includes discussions on the nature of humans, the concept of sin, and the implications of the Fall (the disobedience of Adam and Eve in the Garden of Eden) on human nature.
  • Hamartiology: Hamartiology is related to Anthropology. It is the study of sin. It examines the origin and consequences of sin, as well as the theological understanding of sin’s impact on individuals and society.
  • Soteriology: Soteriology is the study of salvation. It delves into topics like the atonement (how Christ’s death reconciles humanity with God) and justification (how people are declared righteous before God).
  • Ecclesiology: Ecclesiology concerns the study of the Church. It includes discussions on the nature and purpose of the Church, its leadership structure, sacraments or ordinances, and its role in the world. [Note: also grapples with the question of the relationship between the Church and Israel.]
  • Eschatology: Eschatology deals with the study of the last things or end times. This category explores topics like the Second Coming of Christ, the resurrection, judgment, heaven, hell, and the final destiny of humanity.
  • Angelology and Demonology: These categories explore the existence and nature of angels (good and fallen) and demons (including Satan), including their roles in the spiritual realm and interactions with humanity.
  • Covenant Theology: In traditions that emphasize covenant theology, this category explores the biblical covenants as a framework for understanding God’s relationship with humanity. 
  • Scriptural Basis: The Bible is typically the primary source for systematic theology. The theologian will analyze and interpret biblical passages to derive theological truths and principles. Different Christian denominations may emphasize different parts of the Bible or interpret them differently, leading to variations in systematic theology.
  • Historical Development: Systematic theology often takes into account the development of Christian doctrine throughout history. Theological formulations and debates in the early church, as well as those in later centuries, influence how theologians construct their systematic theologies.
  • Creeds and Confessions: Many Christian traditions have produced creeds, confessions, and statements of faith that summarize their core beliefs. Systematic theologians often refer to these documents as they construct their systematic theologies.

Systematic theology serves several purposes, including helping believers deepen their understanding of their faith, providing a basis for teaching and preaching, facilitating theological dialogue and debate, and defending the Christian faith against challenges from other worldviews. It is a rigorous and intellectual pursuit that seeks to explore the richness and depth of Christian theology in a structured and coherent manner.

What Are Other Types of Theology?

In addition to systematic theology, there are several other branches or types of theology that focus on specific aspects of religious study, interpretation, and application. Here are some of the most common types of theology:

  • Biblical Theology: Biblical theology seeks to understand and interpret the theological themes and teachings found within the Bible itself. It examines the historical and literary context of biblical texts and traces the development of theological concepts throughout the biblical narrative. [Example: what does John’s gospel – or the complete works of the apostle John – tell us about the nature of salvation? Compared to the contributions of, say, the apostle Paul. Or: what is the development of thought through the Old Testament about eschatology? How do the gospel writers interact with and expand this?]
  • Historical Theology: Historical theology explores the development of Christian doctrine and theology throughout the history of the Christian Church. It examines the writings and theological debates of theologians and church leaders from different time periods.
  • Comparative Theology: Comparative theology involves the comparison of theological beliefs and practices across different religious traditions. It seeks to understand the similarities and differences between various faiths.
  • Natural Theology: Natural theology explores theological questions through reason, philosophy, and observation of the natural world, rather than relying solely on divine revelation. It seeks to find evidence for God’s existence and attributes in nature and human reason.
  • Practical Theology: Practical theology seeks to connect the academic discipline of theology more fully to the practices of religion and ministry. One subset of practical theology is ethics. Another is pastoral theology, which includes worship, preaching, Christian education, Christian counseling, and disciple making. Another is missiology, the study of the history and methodology of how God’s people pursue his mission throughout the world.

These are just a few examples of the many branches and types of theology that exist. The choice of which type of theology to study often depends on an individual’s interests, theological tradition, and academic or practical goals within their religious community.

Who is Jesus and Why it Matters

Homework
Read Chapters 9 and 11 in Christian Beliefs by Wayne Grudem

Click for Shownotes

In a previous lesson, we touched briefly on the nature of Jesus as part of the Triune God. In this topic, we will explore more fully the very rich and meaningful identity of Jesus, to understand why he is absolutely central to the Christian message. 

The Humanity of Jesus

The Bible attests that Jesus was fully human in body, soul, mind and will (Hebrews 2:17). In his incarnation, the eternal Son of God became fully human (Hebrews 2:14), with all the capacities of original humanity. Jesus experienced all the ordinary limitations of being truly human. He had a real human body, subject to weariness (John 4:6), hunger (Matthew 4:2) and thirst (John 4:7). He was capable of experiencing every human emotion (Matthew 26:37; John 2:15). He was tempted as we are (Matthew 4:1-11). Yet Jesus never sinned (Hebrews 4:15). He was born (Luke 2:7), he grew and developed (Luke 2:52), he suffered (John 19:1-3) and he died (Mark 15:37). Finally, Jesus was resurrected in a human body (Luke 24:39-43) and permanently possesses his human nature. 

It matters a great deal that Jesus is fully human.

  • Because he is human, his atoning death can truly apply to us. As one of us, he can offer a sacrifice on our behalf, as our representative (Hebrews 2:14).
  • In his humanity, Jesus can fully sympathize with and intercede for us. He understands any trial or weakness or temptation we might face (Hebrews 4:15-16).
  • Jesus manifests the true nature of humanity. He shows what God had in mind when he created us.
  • Jesus can be our example. As fully human, we can look to him as a model of the Christian life. He is not just some heavenly superstar, but found it necessary to pray and to live in dependence on the Spirit.
  • Jesus’ humanity shows that the material world is not evil. The physical aspects of our humanity are not inferior to the spiritual, because Jesus took upon himself our full human nature, including a physical body.
  • While God is transcendent, he is not infinitely far removed from the human race. He actually lived among us as a real human person. Jesus’ humanity reminds us that God does act within the human realm, even today.

The Divinity of Jesus 

When Jesus became human, he did not surrender his deity in any way. He remains God the Son, the second person of the Trinity, who is eternally equal to and identical with God (John 1:1, 18; Romans 9:5).

Jesus identified himself with the God who appeared to Moses in Exodus 3:14 (John 8:58). He also defended his own equality and union with the Father (John 10:10). Revelation 1:8 calls God the Father “Alpha and Omega,” a title Jesus applies to himself later in Revelation 22:13. Based on Jesus’ own claims, the New Testament writers saw him as being equal with God in every way (Philippians 2:6; Hebrews 1:3). Quoting Psalm 45, Hebrews 1:8-9 applies the title “God” directly to Jesus.

The Bible attributes to Jesus works that only God can do. He is the agent of creation (John 1:1-8) and exhibits power over what he made (Matthew 14:22-36). He forgives sins (Mark 2:5-7) and judges the world for sins (John 5:22-30). As God, Jesus receives prayer (Acts 7:59-60) and is worthy of worship (Philippians 2:9-11; Hebrews 1:3-6).

As with his humanity, the divinity of Jesus has important implications:

  • We can have real knowledge of God. The prophets came bearing a message from God and about God. But since Jesus is God, we can know what God is like.
  • Salvation is possible for us. Because Jesus is fully God, his death for our sins is sufficient.
  • God and man have been reunited. It was not a created being who bridged the gulf, but God himself crossed the chasm created by sin.
  • Because of his deity, Jesus deserves all the adoration and obedience that is owed to God the Father.

The Two Natures of Christ

So the New Testament attributes both divine and human properties to Jesus, but it never divides him into two persons. He is a single person with two natures: the divine nature that he shares equally and eternally with the Father and the Holy Spirit, and the human nature he took on in his incarnation. These two natures are united in his person without confusion, change or loss. Jesus is not part God and part human, but both are fully integrated in him..

The Offices of Jesus

Historically, theologians have viewed the work of Christ in terms of three “offices” or functions that work in conjunction with each other: prophet, priest and king.

The role of a prophet was to reveal God to humanity. Jesus functioned in many ways like an Old Testament prophet, bringing a message of judgment as well as salvation. In fact, he was the perfect prophet because he perfectly reveals the Father, not just in his words, but in his person (Hebrews 1:1-3; John 14:8)

Priests mediated the relationship between God and his people so they could be forgiven, justified, reconciled to God. Jesus came as the perfect priest (Hebrews 6:20; Hebrews 7:28). By his sacrificial death we were reconciled to God (Hebrews 9:11-12). 

Israel’s kings were given authority to carry out God’s rule on earth. In fact, Israel anticipated a future ruler who would sit on David’s throne forever. The Bible reveals this person to be Jesus (Luke 1:32-33). He now reigns as the perfect king over all creation. He is the head of the church (Colossians 1:18), which reflects his kingdom in the present. But in the future, he will rule universally and exclusively (Philippians 2:9-10).

The Resurrection of Jesus

All four gospels describe in some detail how Jesus rose from the dead, as he predicted he would (John 2:18-22). His resurrection is also mentioned prominently through the rest of the New Testament. 

Jesus’ resurrection was bodily. He rose in a physical body of real flesh, not merely as a spirit (Luke 24:39-40). His resurrection body was similar to his earthly body. People recognized him (John 20:20). He breathed (John 20:22), spoke, and ate with people (Luke 24:41-43). But Jesus’ resurrection body is also different from his mortal body. He entered closed rooms (John 20:19) and appeared and disappeared (Luke 24:30-31). Jesus’ resurrected body is the model of what his people will experience in their resurrection, meaning that his body is a glorified body no longer subject to death or weakness (1 Corinthians 15:42-44; Revelation 1:12-16). 

The resurrection of Jesus is the core of the Christian message. (Acts 2:32; 5:30; 10:40; 13:30). If Jesus did not rise, there is no salvation (1 Corinthians 15:12-19). The resurrection establishes Jesus’ identity as the Son of God and validates his claims as Messiah (Romans 1:3-4), which sets him apart as unique among all religious leaders who ever lived.

The Ascension of Jesus

After Jesus rose from the dead, he spent forty days with his disciples (Acts 1), before he was taken up into heaven (Luke 24:50-53). The ascension demonstrates that Jesus completely finished his work as Savior. Now, he is seated at God’s right hand, representing the position of greatest honor and greatest authority. From there Jesus continues his priestly ministry in a different form, as he intercedes for us (Hebrews 7:25), continually presenting his righteousness to the Father on our behalf. The ascension of Jesus also started the timetable for his return. When Jesus comes back, he will return in a manner similar to how he left: bodily and visibly (Acts 1:9-11).

The person of Jesus is at the heart of Christianity. As the one person who is fully God and fully human, he qualifies to be our prophet, priest and king. He deserves our worship and obedience. But as important as his identity is, the identity and work of the Holy Spirit is also vital. This is the topic of our next lesson.

Talking Points:
  • In a previous lesson we touched briefly on the nature of Jesus. In this topic we explore more fully his person (who he is) and work (what he did). 
  • The New Testament attributes both divine and human properties to Jesus, but it never divides him into two persons. He is a single person with two natures (this is called the “hypostatic union”).
  • Historically, theologians have viewed the work of Christ in terms of three “offices” or functions that work in conjunction with each other: prophet, priest and king.
  • The resurrection of Jesus establishes his identity as the Son of God and validates his claims as Messiah. His ascension demonstrates that he completely finished his work as Savior.

SALVATION

07 The Atonement

The Biblical Doctrine of Atonement

Homework
Read Chapters 10 and 12 in Christian Beliefs by Wayne Grudem

Click for Shownotes

When humanity rebelled against God, God’s love compelled him to act on our behalf to restore the relationship broken by sin. He did this by sending his Son, Jesus Christ, to make atonement. 

Aspects of the Atonement

The word “atonement” originally meant “at-one-ment” – or being in harmony with someone. In Bible translations, the word captures a multi-faceted concept reflecting several key biblical words. At its heart is the idea that human beings can be reconciled to God through the sacrificial suffering and death of Jesus Christ.

Sacrifice 

The first problem addressed by the atonement is that we deserve to die as the penalty for sin. This is pictured vividly in the Old Testament sacrificial system, where sin required death. Whenever an offense against God’s law occurred, an animal was killed in place of the sinner to set the offense right (Leviticus 4:13-14; Leviticus 5:5-6). The book of Hebrews makes clear that these sacrifices pointed forward to the ultimate sacrifice Jesus made on the cross. He is depicted as the high priest who enters the Holy Place of God’s temple to offer a sacrifice for sins (Hebrews 2:17). Yet the sacrifice is not a bull or goat, but his own life blood. In this picture, Jesus is both the priest and the offering (Hebrews 9:11-12).

Propitiation

The second problem the atonement deals with is that we deserve to bear God’s wrath against sin. The wrath of God is his settled animosity toward sin. Wrath is what our sin and rebellion deserve from a holy God. Propitiation means that God’s wrath is averted by offering a gift. That gift is provided by God himself (1 John 4:10) in the person of Jesus (1 John 2:2), who freely offered himself as a sacrifice of propitiation for us by shedding his blood (Romans 3:25).

Redemption 

The third need that the atonement addresses is that we are in bondage to sin and to the kingdom of Satan. Jesus purchased our freedom from the kingdom of darkness (Colossians 1:13-14) and transferred us into his own kingdom. In his grace, God bought our freedom from sin and from the empty life common to humanity, through Jesus’ sacrifice (Ephesians 1:7; 1 Timothy 2:6; 1 Peter 1:18-19).

Reconciliation

The atonement also addresses the problem that we are separated from God. Sin has estranged us from God and made us his enemies. But Christ’s death ends the enmity and brings about peace. God brought us back to himself through Christ (2 Corinthians 5:18) so that we become friends with God (Romans 5:10-11).

Substitution 

All of these aspects of atonement strongly suggest that the death of Christ was a substitute for our own. Jesus died on our behalf (Galatians 1:4; Ephesians 5:2) and in our place (2 Corinthians 5:21; Hebrews 9:28). He bore our sins (1 Peter 2:24; Isaiah 53:5-6) to set aside God’s wrath, set us free from sin, and remove the cause of enmity between us and God. 

Election 

An important and challenging question in Christian theology has to do with how and to whom God applies the atonement of Jesus to peoples’ lives. Two perspectives dominate: Calvinist (Reformed) and Arminian. The two groups differ on whether Jesus’ atoning sacrifice was made for all human beings, or only for those chosen by God for salvation. At the center of this debate is the biblical doctrine of election. Both groups believe in God’s calling and election (Romans 8:30; Ephesians 1:4-5), but differ in what those concepts mean.

The Calvinist position begins with the premise that every human being is born spiritually dead because of sin (Ephesians 2:1). Our sinful nature is completely hostile to God (Romans 8:7). This renders humans totally unable to come to God. God must make a person spiritually alive first, before he or she can appreciate or respond to the work of Christ (Acts 13;48).

Arminians agree that humans are incapable of responding to God on their own, and require an act of God in order to receive the gospel. But they argue that God provides a form of grace (“prevenient grace”) to all humanity that overcomes our inherent human inability, so that anyone can freely choose God if they will.

Calvinists hold that, because humans cannot contribute anything to their own salvation (Ephesians 2:8), only those chosen by God can be saved. God elected people for salvation unconditionally, not based on any attribute within any person, but only on his own decision (Ephesians 1:5; Romans 9:15-16). God intervenes in a person’s life in such a way that his sovereign choice of them is ultimately reflected in their own choice to willingly follow him. Thus when God calls someone to salvation, the call is effectual. That person will be saved.

Arminians believe that God desires all people to be saved (1 Timothy 2:3-4; 2 Peter 3:9), not just some pre-selected number. So God chooses those who will be saved, not on the basis of his sovereign will, but based on his foreknowledge (Romans 8:29). In other words, God has elected those whom he knew in advance would believe in him. Thus when God calls someone to salvation, it is a general call to everyone, which people can accept or reject.

These concepts relate to the atonement because Calvinists believe that Jesus died only for those who would actually be saved: the elect. Arminians believe that Jesus died for everyone, but only those who avail themselves of his atoning sacrifice will be saved. Calvinists cite passages that suggest Jesus’ work applies only narrowly (1 John 10:14-15; Ephesians 5:25), while Arminians focus on passages that speak about Jesus’ death more universally (John 1:29; Hebrews 2:9; 1 John 2:2)

In the end, the differences between Calvinists and Arminians seem great. But generally, both groups agree on the basic message of the gospel that captures the heart of Jesus’ atonement.

Defining the Gospel

The word “gospel” translates the New Testament word meaning “message of good news.” The essential content of this message is Jesus (Romans 16:25). He is both the Messiah and the Son of God, now raised from the dead and Lord of all (Romans 1:1-4; 2 Timothy 2:8). The gospel tells us how God saves sinners to make us right with him (Romans 1:16-17). It promises that those who believe in Christ are enfolded into his people and promised an eternal inheritance (Ephesians 1:12-13). The gospel is the good news that God saved us into a new life, not because we deserved it, but by his grace. Jesus our Savior came to break the power of death and open the way into life and immortality (1 Timothy 1:8-11). In short, the gospel is the hopeful message that Jesus provides the remedy for our sin, both in this life and in eternity, for all who simply believe.

The Bible expands significantly on this core message to proclaim what God has done for sinners, as we will explore in Topic 8.

Talking Points:
  • The concept of atonement is a central theme in the Bible, woven into the narrative of God’s relationship with humanity. It is a theological term that refers to the reconciliation between God and humans, made possible through the sacrifice of Jesus Christ.
  • The atonement addresses several problems: (1) we deserve to die because of our sins, (2) we deserve to bear God’s wrath, (3) we are in bondage to sin, and (4) we are separated from God. Jesus solved all of this by taking our place on the cross: this is the atonement. Romans 3:25
  • A challenging question in Christian theology has to do with how and to whom God applies the atonement of Jesus to peoples’ lives. Two perspectives dominate: Calvinist (Reformed) and Arminian. Romans 8:30
  • The good news of the Bible, or the “gospel”, is all about the atonement. It is the hopeful message that Jesus provides the remedy for our sin, both in this life and in eternity, for all who simply believe. Romans 1:16-17

In our last topic, we focused on key aspects of Jesus’ work of atonement. This topic looks more specifically at the results of Jesus’ work in the believer’s life, outcomes collectively known as “salvation.” 

The Definition of Salvation

Broadly speaking, salvation is the application of the work of Christ to the life of individual persons. At its core, the word means “deliverance” – whenever a serious need or peril arises, and a person is rescued from that peril. In our relationship with God, the primary peril is sin. From this, a variety of secondary needs arise: alienation from others, social injustice, violence, guilt and shame, and many more. Thus salvation is not limited to forgiveness of sin and life after death. It involves the entire person and the full extent of God’s care and compassion, both now and in eternity. Salvation means that those far away are brought near, what is broken is repaired, the condemned are acquitted, the wounded are healed, the dying are given life, the impure become clean, and enemies become friends.

This suggests that salvation has past, present, and future aspects. Some aspects of salvation have already been applied to believers. Other elements relate to God’s ongoing, transforming work in our lives. Some have to do with the life to come after we die. So our salvation is both complete and incomplete, in one sense. We possess salvation, in Christ, and nothing can be added to it. Yet we have not yet experienced everything promised to us in our salvation.

Regeneration 

Regeneration means “new birth”. It involves restoring and re-creating a person from spiritual death to spiritual life (Ephesians 2:1-5). This new birth is completely a work of God on our behalf (John 1:13). It is a gracious gift of God (1 Peter 1:3), not accomplished by any human agency or effort, including any effort on our part. Regeneration is necessary for salvation, since no one can enter the kingdom of God unless he or she is “born again” (John 3:3-5, 7). 

Literally, regeneration is the beginning of a new life as a new creation of God (Galatians 6:15; 2 Corinthians 5:17). This new birth is instantaneous. At one moment, a person moves from spiritual death to life, as something entirely new is created that reverses his or her natural tendencies (Titus 3:3-5). The new birth gives us optimism that broken humans can be transformed and restored, through God’s supernatural power at work in us.

Regeneration is the beginning of a process of growth and development. Having been granted new life, the believer responds by putting the old life to death (Ephesians 4:21-22; Colossians 3:5-9) and choosing to live out the reality of their new nature (Romans 6:4; Ephesians 4:23-24; Colossians 3:10).

Conversion

Conversion marks the beginning of the Christian life. Conversion is the individual’s response to the gospel invitation. It can be considered as a single event with two inseparable aspects: repentance and faith (Mark 1:15; Acts 20:21). 

The best way to express the biblical word translated “faith” is “trust”. Faith is the act and attitude of entrusting oneself to the faithfulness of God, both for initial salvation and in ongoing relationship with God. Faith is a gift given by God (Philippians 1:29; Ephesians 2:8-9) and results from hearing the message of the gospel (Romans 10:17). Faith has often been thought of in three coordinated aspects: knowledge (a grasp of the truth), assent (agreement with the truth), and trust (confidence or reliance on the truth). Yet faith is not just a response to facts, but to a person.

Repentance is the act and attitude of turning from sin and self to God, through Jesus Christ (2 Corinthians 12:21; Revelation 2:21-22). There is no salvation without repentance. Repentance is not merely feeling sorry for sin (2 Corinthians 7:10), but is a foundational decision that orients our hearts toward God, both for initial salvation and in an ongoing relationship with God. The validity of any person’s repentance will eventually be demonstrated by a changed life (Acts 26:20).

Actual conversion is instantaneous, but viewed from a human perspective, it may not be possible to pinpoint when it occurred. At some point, a person responds to the gospel in repentance and faith and is made alive by God. But the reality of that conversion may not be apparent until much later, as it begins to bear fruit.

Justification 

Human beings have two problems as a result of sin and the fall. First, our nature is corrupted by the effects of sin. Sin has polluted our moral character. This problem is answered by regeneration (above). Second, we come under guilt and condemnation because we have violated God’s law. This problem is answered by justification, which is “the declaration by God that we are righteous in his sight.”

In justification, God’s verdict about us changes from blame to acquittal. On one hand, our sins are pardoned. Borne by Jesus in our place, the penalty of sin is removed as an act of God’s pure grace (Romans 3:23-24). Thus forgiveness of sins is at the heart of Jesus’ mission (Matthew 26:28; Hebrews 9:22) and of the mission he gave his disciples (Luke 24:47; John 20:23).

On the other hand, God accepts us as righteous. Forgiveness brings us to a neutral position before God. Yet for God not only to declare us “not guilty” but righteous, Christ’s own righteousness is imputed to our account (Romans 5:18-21; 2 Corinthians 5:21). In other words, God counts us as righteous based on our faith in Jesus (Romans 4:4-5; Philippians 3:7-9). Justification removes the eternal judgment that our sin deserves, yet we may still suffer for our sin in this life – in our relationships, for example.

Adoption

In Topic 7, we touched on reconciliation. Through Jesus, we have been transferred from a position of alienation and hostility to one of acceptance and favor. The most prominent metaphor in the Bible for reconciliation is the parent-child relationship. Those who trust in Christ are now viewed as children and heirs of God, by virtue of a spiritual adoption (John 1:12; Ephesians 1:5; Romans 8:15).

Adoption occurs at the same time as regeneration, conversion and justification. While no personal relationship is implied by justification, adoption makes us recipients of God’s fatherly care (Matthew 7:9-11) as we are welcomed into intimacy with him (Romans 8:15-17). We now have a relationship with God that is defined not by compulsion or obligation, but by love (Galatians 4:4-7).

Eternal Life

Spiritual and physical death are consequences of human sin, so it is no surprise that salvation is often framed as “life” or “eternal life.” This is usually connected with the future resurrection of believers (John 5:21; Titus 3:7). But eternal life is not limited to a post-mortem future in heaven. It is a quality of life that begins in this world (John 5:24; 1 John 3:14), when a person comes to Jesus (John 3:15-16; John 20:31; 1 Timothy 1:16; 1 John 5:11-12), as the one who gives this life (John 5:39-40; John 8:12; John 10:10, 28). 

Union with Christ 

The Bible repeatedly refers to Christians using the phrase “in Christ” or “in the Lord” (Romans 16:9; 1 Corinthians 7:22; Galatians 3:28; Ephesians 2:10; Philippians 4:7; 2 Timothy 2:1). For example, anyone “in Christ” is a new creation (2 Corinthians 5:17). God has blessed us and chosen us “in Christ” (Ephesians 1:3-4). 

At the same time, the Bible speaks of Christ being in the believer. “Christ in you,” Paul says, is “the hope of glory” (Colossians 1:27). He declares, “It is no longer I who live, but Christ lives in me” (Galatians 2:20). In this union, Jesus’ life flows into ours, by faith, renewing our inner nature and producing his fruit through us (John 15:5).

The work of Jesus Christ has astounding benefits in the lives of those who come to him in repentance and faith. But his saving work does not end with our initial conversion. The work of Christ has ongoing effects to transform our lives, which we will explore in Topic 9: The Christian Life.

Talking Points:
  • Salvation is the application of the work of Christ to the life of individual persons. At its core, the word means “deliverance”. In this topic we’ll explore several elements of salvation and the vocabulary associated with it.
  • Regeneration is the beginning of a new life as a new creation of God. This new birth is instantaneous. Galatians 6:15; 2 Corinthians 5:17
  • Conversion is the individual’s response to the gospel invitation. It can be considered as a single event with two inseparable aspects: repentance and faith. Mark 1:15; Acts 20:21
  • In justification, God’s verdict about us changes from blame to acquittal. The penalty of sin is removed as an act of God’s pure grace. Romans 3:23-24
  • The work of Jesus Christ has additional benefits in the lives of those who trust in him, such as adoption, eternal life, and union with Christ. But his saving work does not end with our initial conversion, as we’ll learn next week.
