They say that God says to me, “Forgive your enemies.” I say, “I do;” but he says, “I will damn mine.” God should be consistent. If he wants me to forgive my enemies he should forgive his. I am asked to forgive enemies who can hurt me. God is only asked to forgive enemies who cannot hurt him. He certainly ought to be as generous as he asks us to be. And I want no God to forgive me unless I am willing to forgive others, and unless I do forgive others. All I ask, if that be true, is that this God should act according to his own doctrine.
