The other day I was reading a missionary book and ran across a story about a man who practiced sorcery and ended up believing, being baptized, and seeking discipleship from the missionary. The man was really well known in his city. Everyone believed that this man had a lot of power and could really change things. The people probably had some idea that the power he was using wasn't good (it was actually demonic) but it was really undeniable that this power was real. It doesn't take much for a man to claim he has a lot of power but this man was actually able to convince everyone that he was great.
