The reason there is no condemnation for us is not that there is nothing in our lives worthy to condemn. Jesus stood in our place and took the condemnation for us when he died on the cross.
What the law was powerless to do… God did by sending his own Son in the likeness of sinful man to be a sin offering. And so he condemned sin in sinful man. Romans 8:3 (NIV)
God the Father saw that we were completely hopeless and he had compassion. He sent the Son to be the Savior of the world—the incarnation. Jesus was like us because his humanity was real. Jesus was different from us because he was without sin. He was close enough to make the rescue, but distinct enough to be the rescuer.
“Here’s what it will mean for you to make the rescue, Jesus: Leave heaven and be born as a man. Live a perfect life, the life none of them have ever lived. Then lay down that life. Become the sin bearer. Take on yourself the guilt and stench of human sin. Bear the condemnation in your own body. Carry it utterly alone, suspended on a wooden pole between heaven and earth—rejected by both. That’s what it will take to rescue them.” That’s an extraordinary job description and Jesus said, “I’ll do it!”
God rescues us by condemning our sin in Christ: “He was pierced for our transgressions; he was crushed for our iniquities; the punishment that brought us peace was upon him” (Isa. 53:5). The reason there is no condemnation for us is not that there is nothing in our lives worthy to condemn. Jesus stood in our place and took the condemnation for us when he died on the cross.
Try to see all your sins laid on Jesus. If the guilt of your selfishness, pride, impatience, and all your other sins has really been transferred to him, and if he suffered the penalty for these on the cross, then the condemnation is no more.
