I think a better title for this thread would be “Christianity and Witchcraft Don’t Mix.”
Sadly, witches don’t understand that they are using the powers of Satan in order to accomplish their will, generally through casting spells, etc. Conversely, Christians pray so that God’s will is done as Jesus taught us to pray in the Lord’s Prayer. And as we pray that God’s will be done, HIS power accomplishes His will.
I believe that a Christian can be deceived for a time and fall into the sin of witchcraft or other occult practices. But using the powers of Satan destroys a Christian’s walk and witness. IOW, no one can really be a good Christian and a “good” witch. They cannot represent both kingdoms—the kingdom of God and that of Satan—at the same time. No one can serve two masters.
