Jesus bore the penalty of sin and dying in our place. God made you alive with Christ. He forgave us all our sins having canceled the charge of our indebtedness, which stood against us and condemned us; He has taken it away, nailing it to the cross. God will never see believers in Christ as deserving the death penalty because our crimes have already been punished in the physical body of Jesus. In order for us to be saved, Jesus had to take our place and die for sin. He had to lay down His life as a sacrifice, because without the shedding of blood there is no forgiveness. His sacrifice was perfect in holiness, in worth and in power to save.
