What does it mean to be crucified with Christ (Galatians 2:20)?

from the old testament

• In the sacrificial system, an innocent animal died in place of the sinner (Leviticus 16; Isaiah 53:5–6), which shows that sin brings death. But God made it possible to have a substitute, which is ultimately fulfilled in Christ.
• God promised the need for deeper transformation with a new heart. He said, “I will give you a new heart and put a new spirit within you” (Ezekiel 36:26–27).
• The call to “circumcise your heart” (Deuteronomy 10:16) pointed to inner surrender to God. This lays the foundation for being "crucified with Christ."

from the new testament

• Galatians 2:20 says, “I have been crucified with Christ. It is no longer I who live, but Christ who lives in me. And the life I now live in the flesh I live by faith in the Son of God, who loved me and gave himself for me.” Through faith, the believer is spiritually united with Jesus in His death. The old self is considered put to death with Him. There is a radical identity shift. The believer now has a new source of life: Jesus Himself, through the Holy Spirit, who shapes all things. The Christian life is now also lived in trust in Jesus, the one who "loved me and gave himself for me."
• Believers are united with Jesus in His death so that sin no longer defines them (Romans 6:6–7). We die to sin and are raised to life in Him when we trust in Him.
• Second Corinthians 5:17 says that we have a new identity and life when we trust in Christ. This is because we are crucified with Christ, crucifying the flesh, and raised to new life in Him. We become new creations.
• There are several other verses that talk about crucifying, or putting to death, the flesh. 
  Ephesians 4:22–24 says to “put off your old self… and be renewed… and put on the new self, created after the likeness of God in true righteousness and holiness.” Colossians 3:5-10 and Romans 13:12-14 teach similar truths.
• Instead of living for the flesh, we are to live in the Spirit (Galatians 5:16–17). 
  
• Galatians 5:24–25 says that “those who belong to Christ Jesus have crucified the flesh with its passions and desires.”
• Life and goodness are the results of being crucified with Christ and living in the Spirit and for the things of God (Romans 8:12–13; Titus 2:11–12).

implications for today

Being a Christian isn't like "upgrading" an app. We get a completely different app when we come to Christ because we are called to put to death our old self and to put on Christ. This means the old patterns, desires, and identities that once controlled us no longer get to run our lives. We don’t just tweak behavior, we surrender control and let God transform us from the inside out. Our old way of life—driven by sin, self-rule, and independence from God—must no longer be the driving force of our lives. We must crucify it.

This means we can no longer negotiate with sin as if it still has authority. We must actively reject it because it belongs to a life that has already been nailed to the cross with Jesus. Instead of asking how far we can go without crossing a line, we start asking whether our choices actually fit the identity of someone who has died with Christ and now lives by faith in Him.

At the same time, this is not just about restriction—it’s about replacement. When we trust in Jesus for the forgiveness of sins, He now lives in us! We don't need to be dragged down and categorized by our sin!

So we must build our lives around staying near Him: letting Scripture shape our thinking, letting prayer interrupt our impulses, and letting accountability and community keep us anchored even before we drift. Being crucified with Christ means we are no longer trying to become a new person on our own; we are learning to live out what is already true. Our life is now hidden with Christ, and He is actively reshaping everything about who we are from the inside out.
