“Scripture consistently teaches that we never have a right to do evil, and that we should persistently oppose it in ourselves and in the world. We are to pray, “Deliver us from evil” (Matt. 6:13), and if we see anyone wandering from the truth and doing wrong, we should attempt to bring him back. Scripture says, “If any one among you wanders from the truth and someone brings him back, let him know that whoever brings back a sinner from the error of his way will save his soul from death and will cover a multitude of sins” (James 5:19–20). We should never even will evil to be done, for entertaining sinful desires in our minds is to allow them to “wage war” against our souls (1 Peter 2:11) and thereby to do us spiritual harm. If we are ever tempted to say, “Why not do evil that good may come?” as some people were slanderously charging Paul with teaching, we should remember what Paul says about people who teach that false doctrine: “Their condemnation is just” (Rom. 3:8). In thinking about God using evil to fulfill his purposes, we should remember that there are things that are right for God to do but wrong for us to do: He requires others to worship him, and he accepts worship from them. He seeks glory for himself. He will execute final judgment on wrongdoers. He also uses evil to bring about good purposes, but he does not allow us to do so. Calvin quotes a statement of Augustine with approval: “There is a great difference between what is fitting for man to will and what is fitting for God … For through the bad wills of evil men God fulfills what he righteously wills.”14 And Herman Bavinck uses the analogy of a parent who will himself use a very sharp knife but will not allow his child to use it, to show that God himself uses evil to bring about good purposes but never allows his children to do so. Though we are to imitate God’s moral character in many ways (cf. Eph. 5:1), this is one of the ways in which we are not to imitate him.”
