 The gospel is simple. You can't save yourself. So Jesus, who is God, came to earth by the power of the Holy Spirit. The Creator stepped into creation, lived a perfect sinless life, and then took the punishment for your sinful one. It was God's mercy meeting your rebellion. It was God's compassion meeting your stubbornness. It was Christ's purity meeting your guilt. And on that cross, when he died, he took upon himself the punishment for those sins. Jesus died upon that cross in your place. And now, when you put your faith in Jesus and God looks at the cross, he sees your sin. And when he sees you, he sees Christ's perfection. It's the great exchange.
