The Sacrifice for Sin
For God presented Jesus as the sacrifice for sin. People are made right with God when they believe that Jesus sacrificed his life, shedding his blood. This sacrifice shows that God was being fair when he held back and did not punish those who sinned in times past . . . .
Rom. 3:25 NLT
Last week, a young man in my parish, asked what the word, “atonement,” meant. His request made me go back and rethink my answer. In summary, atonement is the work that Christ did in his life, death, burial, resurrection, and ascension, which provided the way for us to come back to God in right relationship.
J. I. Packer writes “Atonement means making amends, blotting out the offense, and giving satisfaction for wrong done; thus reconciling to oneself the alienated other and restoring the disrupted relationship” (Concise Theology: A Guide to Historic Christian Belief). I have heard several preachers reflect that atonement means “at-one-ment,” Jesus’s sacrifice has given us the opportunity to be in “oneness” with our heavenly Father.
God displays his righteousness by judging sin as sin deserves, but the judgment is diverted from the guilty and put on to the shoulders of Jesus Christ, the sinless Son of God acting as wrath absorber. The atonement had to be costly because it was necessary in light of the nature of God, which must inflict retributive punishment on sin. A marvelous wisdom of God consists in his establishing the Lord Jesus as our representative and our substitute because only he could bear and absorb the judgment due to us. Being our representative makes him our substitute, and so he suffers and we go free . . . .
