That Christ was the perfect sacrifice for sin is an essential New Testament truth. The Book of Hebrews expresses that important reality repeatedly, nowhere more clearly and forcefully than in 10:10-14: “By this will we have been sanctified through the offering of the body of Jesus Christ once for all. And every priest stands daily ministering and offering time after time the same sacrifices, which can never take away sins; but He, having offered one sacrifice for sins for all time, sat down at the right hand of God, waiting from that time onward until His enemies be made a footstool for His feet. For by one offering He has perfected for all time those who are sanctified.”
Christ “died to sin” not only to break its power but to pay its penalty— death (Rom. 6:23)—on our behalf. “He Himself bore our sins in His body on the cross,” wrote Peter, “that we might die to sin and live to righteousness; for by His wounds you were healed” (1 Peter 2:24).
