This is the reason why it is crucial to distinguish anger from hatred. There is a kind of anger (nonsinful kind) which...is in God himself, while hate is not in God but is in Satan. If we do not clearly distinguish anger from hatred, then we do not clearly distinguish God from Satan!
Peter KreeftOf course the more you love the sinner the more you hate and make war on the sin, just as the more you love the person, the more you hate and kill the cancer cells that are killing the person. Compassion for cancer cells does not come from compassion for persons; it comes precisely from lack of compassion for persons.
