BTW, don't forget that the Bible says that other people may also perform the same miracles by invoking Jesus' name (Matthew 7:22, Mark 9:38-39, 16:17-18, Luke 9:49-50, 10:17, Acts 3:6-7, 4:7-10, 30, 19:13-17, 1 Corinthians 12:9-10). Those miracles aren't exclusive to Jesus alone.
And here is a pretty amusing statement condemning illusionists who might to imitators of what demons ACTUALLY DO:
*** w64 10/15 pp. 639-640 Questions From Readers ***
It may be that a person has a hobby of performing tricks that have nothing to do with real magic or demonism. It may be that one simply employs sleight-of-hand tricks or those involving illusions. So if one were merely showing how adroit a person may be with his hands, with no pretense of any magic, there may be no objection to such entertainment. However, whether a Christian will be involved in things of this nature or not is something that should be thoughtfully considered. One might start out performing simple tricks, but this could lead into practices that, knowingly or unwittingly, mimic the magical arts. One might duplicate by trickery real magical feats that are performed by demons, such as levitation, moving objects mysteriously, ectoplasmic materializations, and so forth. Such could lead into involvement with wicked spirit forces because it is playing at what the demons actually do.
