To render good for evil is divine. To render good for good is human. To render evil for evil is brutish. But to render evil for good is devilish!
Evil is often the perversion of something good that God has created.
Evil is a parasite. It is there only because good is there for it to spoil and confuse.
Mention of the “schemes” of the devil reminds us of the trickery by which evil and temptation present themselves in our lives. Evil rarely looks evil until it accomplishes its goal; it gains entrance by appearing attractive, desirable, and perfectly legitimate. It is a baited and camouflaged trap (Klyne Snodgrass).
Men never do evil so completely and cheerfully as when they do it from religious conviction.
