In Romans it says, “No one can be made right with God by following the law. The law only shows us our sin” Romans 3:20 (NCV).
But we do need to put on the righteousness of Christ. His perfection can be yours through proxy. That is what the rebirth is all about. Have you taken on the righteousness of Jesus? That happens when you place your faith in Christ. That means you surrender your all to Him and follow Him. There is more to believing than meets the eye.
