When someone is saved, God applies the work of Jesus to their life. Regeneration is the new birth God gives. Conversion is our response of repentance and faith. Justification is God’s declaration that we are righteous. Adoption makes us his children. And we receive eternal life and union with Christ. Salvation touches the whole person and has past, present, and future dimensions.
What Is Salvation?
In Lesson 8, we looked at what Jesus accomplished on the cross. Now we look at the results of his work in a believer’s life, which are collectively known as salvation.
At its core, salvation means deliverance, being rescued from danger. Our primary danger is sin. But sin creates many other needs too: alienation from others, injustice, violence, guilt, shame, and more. So salvation isn’t limited to forgiveness and life after death. It involves the whole person and the full extent of God’s care, both now and forever. In salvation, those far away are brought near, the broken are repaired, the condemned are acquitted, the wounded are healed, the dying receive life, the impure are made clean, and enemies become friends.
Salvation also has past, present, and future aspects. Some parts have already been applied to believers. Some relate to God’s ongoing work in our lives. Others concern the life to come. In one sense, our salvation is complete. Nothing can be added to it. Yet we haven’t experienced everything it promises yet.
Regeneration: A New Birth
Regeneration means new birth. It’s God’s work of re-creating a person from spiritual death to spiritual life (Ephesians 2:1-5). It is entirely God’s doing (John 1:13), a gracious gift (1 Peter 1:3) that no human effort can produce. And it’s necessary. Jesus said no one can enter God’s kingdom without it.
John 3:3 Jesus replied, “Very truly I tell you, no one can see the kingdom of God unless they are born again.”
Regeneration makes us a new creation (2 Corinthians 5:17; Galatians 6:15). It happens instantly. In one moment, a person passes from death to life as something entirely new is created that reverses their natural tendencies (Titus 3:3-5). That gives us real hope that broken people can be transformed by God’s power.
Regeneration is also the beginning of a process of growth. Having received new life, the believer responds by putting the old life to death (Colossians 3:5-9) and living out their new nature (Ephesians 4:22-24). We’ll explore that process in Lesson 10.
Conversion: Repentance and Faith
Conversion is our response to the gospel invitation, and it marks the beginning of the Christian life. It’s a single event with two inseparable sides: repentance and faith (Mark 1:15; Acts 20:21).
Faith is best understood as trust. It’s entrusting yourself to God’s faithfulness, both for salvation and for an ongoing relationship with him. Faith comes from hearing the gospel (Romans 10:17), and even faith is a gift from God.
Ephesians 2:8-9 For it is by grace you have been saved, through faith—and this is not from yourselves, it is the gift of God—not by works, so that no one can boast.
Faith has often been described in three parts: knowledge (understanding the truth), assent (agreeing with it), and trust (relying on it). But faith isn’t just a response to facts. It’s a response to a person.
Repentance is turning from sin and self toward God through Jesus. There is no salvation without it. Repentance isn’t just feeling sorry (2 Corinthians 7:10). It’s a foundational decision that orients our hearts toward God. True repentance will eventually be demonstrated by a changed life (Acts 26:20).
Conversion happens in an instant, though from a human perspective it may be hard to pinpoint when it occurred. The reality of someone’s conversion may not be obvious until it starts bearing fruit.
Justification: Declared Righteous
Sin left us with two problems. First, our nature is corrupted. Regeneration solves that. Second, we stand guilty and condemned for breaking God’s law. Justification solves that. Justification is God’s declaration that we are righteous in his sight.
In justification, God’s verdict changes from guilty to acquitted. Our sins are pardoned as an act of pure grace, because Jesus bore the penalty in our place.
Romans 3:23-24 For all have sinned and fall short of the glory of God, and all are justified freely by his grace through the redemption that came by Christ Jesus.
Forgiveness is at the heart of Jesus’ mission (Matthew 26:28) and the mission he gave his followers (Luke 24:47). But justification does more than bring us back to neutral. God credits Christ’s own righteousness to our account (Romans 5:18-19; 2 Corinthians 5:21). He counts us as righteous because of our faith in Jesus, not because of our works (Romans 4:4-5; Philippians 3:9). Justification removes the eternal judgment our sin deserves, though we may still experience consequences of sin in this life, such as damaged relationships.
Adoption: Children of God
In Lesson 8, we saw that Jesus reconciles us to God. The Bible’s favorite picture of that reconciliation is a parent and child. Everyone who trusts in Christ is adopted as a child and heir of God (John 1:12; Ephesians 1:5).
Romans 8:15 The Spirit you received does not make you slaves, so that you live in fear again; rather, the Spirit you received brought about your adoption to sonship. And by him we cry, “Abba, Father.”
Adoption happens at the same time as regeneration, conversion, and justification. But justification is a legal standing, while adoption is a relationship. It makes us recipients of God’s fatherly care (Matthew 7:9-11) and welcomes us into intimacy with him (Romans 8:15-17). Our relationship with God is no longer defined by obligation, but by love (Galatians 4:4-7).
Eternal Life
Since death is a consequence of sin, it’s no surprise that salvation is often described as life, or eternal life. This is often connected with the future resurrection of believers (John 5:21; Titus 3:7). But eternal life isn’t just a future in heaven. It’s a quality of life that begins the moment a person comes to Jesus (John 5:24; 1 John 5:11-12), the one who gives life to the full (John 10:10).
Union With Christ
The New Testament repeatedly describes Christians as “in Christ” or “in the Lord” (Romans 16:9; Galatians 3:28; Ephesians 2:10; Philippians 4:7). Anyone in Christ is a new creation (2 Corinthians 5:17). God has blessed and chosen us in Christ (Ephesians 1:3-4).
The Bible also speaks of Christ living in the believer. “Christ in you” is “the hope of glory” (Colossians 1:27).
Galatians 2:20 I have been crucified with Christ and I no longer live, but Christ lives in me. The life I now live in the body, I live by faith in the Son of God, who loved me and gave himself for me.
In this union, Jesus’ life flows into ours, renewing our inner nature and producing his fruit through us (John 15:5). Everything God gives us in salvation, we receive in him.
The Takeaway
Salvation is far bigger than a ticket to heaven. When we trust Jesus, God gives us new birth, forgives our sins, declares us righteous, adopts us into his family, gives us eternal life, and unites us with Christ. And his saving work doesn’t end at conversion. In Lesson 10, we’ll see how a saved person grows.
