If God is not harmed, then who is harmed?
Schoonenberg noted: Ultimately it is sinful man himself that is harmed by sin. (This is explicit in Jer. 7:18 and Job 35:5-8.)
Schoonenberg continued: We are standing here before the mystery of God himself, of his transcendence and immanence. There is no possibility of solving this question like a math problem. But, we may try to appreciate the mystery.
