“He himself carried our sins” in his body on the cross. (Isaiah 53:5) He did it so that we would die as far as sins are concerned. Then we would lead godly lives. “His wounds have healed you.” (Isaiah 53:5)
Christ also suffered once for sins. The one who did what is right suffered for those who don’t do right. He suffered to bring you to God. His body was put to death. But the Holy Spirit brought him back to life.
