The God of Exodus is the same God as in Mathew, Mark, Luke and John. Jesus never condemned witches because there were no living witches in Israel in the time of Jesus. That was largely due to Exodus.
You are correct that I don’t own Christianity: Christianity owns me.
I do know that people who claim to be witches are fools, insane or evil. Which are you? A bit of all three, if you charge people money to learn about witchcraft. You would be smart, sane and good to seek Christ instead of Satan before your life gutters out. You have time to change, but not very much time.
