The short answer: Jesus died on the cross to pay for our sins and bring us back to God. Sin separates every person from God and earns death. Jesus, who never sinned, took our place and our penalty: "For Christ also suffered once for sins, the righteous for the unrighteous, that he might bring us to God" (1 Peter 3:18, ESV). He gave His life willingly, out of love, and rose again on the third day. Anyone who trusts Him is forgiven.
The Problem: Sin
The cross only makes sense when we see the problem it solved. "For all have sinned and fall short of the glory of God" (Romans 3:23, ESV). Sin is not just breaking rules. It is turning away from the God who made us. And it has a cost: "For the wages of sin is death" (Romans 6:23, ESV). God is holy and just, so He does not simply ignore evil. That is good news for a world full of injustice, and hard news for us, because we are part of the problem.
The Substitute: Jesus in Our Place
But he was pierced for our transgressions; he was crushed for our iniquities; upon him was the chastisement that brought us peace, and with his wounds we are healed. All we like sheep have gone astray; we have turned—every one—to his own way; and the LORD has laid on him the iniquity of us all.
Isaiah wrote that about seven hundred years before Jesus (Isaiah 53:5–6, ESV). The New Testament says it was fulfilled at the cross: "He himself bore our sins in his body on the tree, that we might die to sin and live to righteousness" (1 Peter 2:24, ESV). Paul puts it in one sentence: "For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God" (2 Corinthians 5:21, ESV).
Jesus took what we deserved so that we could receive what He deserved.
The Motive: Love
The cross was not an accident, and Jesus was not a victim of events. He said, "No one takes it from me, but I lay it down of my own accord" (John 10:18, ESV). Why? "But God shows his love for us in that while we were still sinners, Christ died for us" (Romans 5:8, ESV). "In this is love, not that we have loved God but that he loved us and sent his Son to be the propitiation for our sins" (1 John 4:10, ESV). "Propitiation" means a sacrifice that satisfies God's justice and turns away His judgment.
What the Cross Accomplished
- Forgiveness. God cancelled "the record of debt that stood against us with its legal demands. This he set aside, nailing it to the cross" (Colossians 2:14, ESV).
- Peace with God. We were far off and have been brought near (1 Peter 3:18).
- Freedom from sin's power. "That we might die to sin and live to righteousness" (1 Peter 2:24, ESV).
- The final sacrifice. John the Baptist called Jesus "the Lamb of God, who takes away the sin of the world" (John 1:29, ESV). The sacrifices of the Old Testament pointed to Him, and no other sacrifice is needed.
"It Is Finished"
Just before He died, Jesus said, "It is finished" (John 19:30, ESV). Not "I am finished." The work of paying for sin was complete. There is nothing left for you to add. That is why salvation is a gift received by faith, not a wage earned by effort. See what grace means.
The Cross Is Not the End
Jesus "was delivered up for our trespasses and raised for our justification" (Romans 4:25, ESV). The resurrection is God's public declaration that the payment was accepted and death is defeated. A dead saviour could not save anyone. Jesus is alive. See who Jesus is.
How to Respond
The cross calls for a response. Turn from your sin and put your trust in Jesus, who died for you and rose again. Paul's own response was this: "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" (Galatians 2:20, ESV). See Know Jesus and what repentance means.
Common Questions
Why did Jesus have to die? Because sin earns death (Romans 6:23) and God is just. Jesus, who was sinless, died in our place to take the penalty for our sins, "the righteous for the unrighteous, that he might bring us to God" (1 Peter 3:18).
What does it mean that Jesus died for our sins? It means He took our place. God "laid on him the iniquity of us all" (Isaiah 53:6), and Jesus "bore our sins in his body on the tree" (1 Peter 2:24), so that everyone who trusts Him is forgiven and counted righteous (2 Corinthians 5:21).
Did Jesus choose to die? Yes. Jesus said, "No one takes it from me, but I lay it down of my own accord" (John 10:18). He gave His life willingly, out of love (Romans 5:8).
What did Jesus mean by "It is finished"? He meant the work of paying for sin was complete (John 19:30). Nothing needs to be added to what He did, which is why salvation is received as a gift through faith.
In our place. For our sins. Because He loves us.
