A British Baptist minister, Steve Chalke, refers to Christ’s death on the cross as “cosmic child abuse” because the Father allegedly violently forced His Son to atone for sins that the Son didn’t commit. There’s much to say about this, but I just want to point out one thing: Jesus said, “I and the Father are one” (John 10:30). God didn’t sacrifice someone else, He sacrificed Himself (cf. Philippians 2:5-8).
Why sacrifice anyone at all? Because God is holy and does not abide sin, and He is also just, so sins must have consequences. Pastor Steven Cole put it this way: “God must maintain His absolute justice by punishing all sin. An unjust ‘God’ would not be God at all. There’s the rub: If God must punish all sin to maintain His absolute justice, then how can He forgive sinners? If a human judge started ‘showing love’ by pardoning murderers and terrorists and rapists, we’d say, ‘Wait a minute! This is horrible! He’s not upholding justice.'”
So, sins must be punished. Consequences must be borne. It is out of love for us that God bore the consequences of our sins Himself.
