Witchcraft is a work of the flesh, and God views it like He views adultery and murder. As such, it should have no place in the life of a believer.
Witchcraft, magic, and other similar practices are very lucrative. In fact, the love of money is at the root of this evil just as it is all others.
There are always two spirits at work: the Holy Ghost and a satanic or false spirit. Witchcraft comes from a satanic spirit and opposes God's Spirit.
