““The difference between the dark magic of the Egyptian magicians and Elymas on the one hand, and Moses and Paul on the other was not what they were doing, but the source of their power. Indeed, what distinguishes sorcery, witchcraft, and black magic from godly miracles, signs, and “white magic” is the source of power (God or demons) and the purpose of the power (worshiping the true God and serving people, or worshiping idols and dominating people).””
