Part 5: The Remedy for Sin — The Cross and Repentance
We’ve followed sin from its definition to its origin, effects, and exposure through the Law. And by now, the picture is clear: we are powerless to fix what’s broken. We cannot save ourselves. But we are not left without hope. God Himself provides the remedy.
That remedy is not a new law, not a better effort, not a fresh start. It is a Savior — Jesus Christ — who takes our sin upon Himself and offers us His righteousness in return.
Atonement: Christ Took Our Place
At the heart of the gospel is a great exchange. Jesus, the sinless One, took on our guilt, bore our punishment, and died our death so we could live His life.
“God made him who had no sin to be sin for us, so that in him we might become the righteousness of God.” — 2 Corinthians 5:21
This is not symbolic. It is substitution. Jesus didn’t just die to inspire us — He died to redeem us.
“He himself bore our sins in his body on the cross…” — 1 Peter 2:24
The cross is where justice and mercy meet. Sin demanded death. Jesus paid it—fully and forever.
Repentance: Our Response to Grace
But grace demands a response—not of earning, but of surrender. That response is called repentance. Repentance is more than feeling sorry. It is a turning — from sin to God, from self-reliance to faith, from death to life.
“Repent, then, and turn to God, so that your sins may be wiped out…” — Acts 3:19
God doesn’t ask for perfection. He asks for a humble heart that turns back to Him. The path to redemption is not paved with performance but with trust.
Sin’s Power Is Broken
Through the cross, sin’s grip is shattered. We may still stumble, but we no longer live as slaves. Jesus broke the curse. The resurrection sealed the victory. Now, those who trust in Him are not just forgiven—they are new.
This is the miracle of grace: we who were once enemies of God are now His children.
“There is now no condemnation for those who are in Christ Jesus.” — Romans 8:1
The Remedy Is a Person
Salvation is not found in a formula. It’s not about being spiritual or religious. It’s about knowing Jesus—the One who entered our brokenness, carried our sin, and conquered our death.
He is the only remedy that truly heals.
