Yes. Witchkraft is real and it works. So does satanism and ocultism, but it has terrible concecuences. If you go in, you cant get out, but if you dont get out, you go to hell. The only way to get out and be okay is accepting Jesus. If you try getting out and you dont accept Jesus, the demons will haunt you. No matter if it is ocultism, witchkraft or satanism. All come from the devil.

It's as real as any other religion or spiritual practice can be. Spells aren't the hocus pocus stuff that you see in Harry Potter, but instigators for things that we wish to happen, or ways to help us get negative things out of our lives. Tarot cards and other divination tools can help us predict the future, however vague it may be. Witches are those the practice withcraft. Most Wiccans label themselves as witches. If religious, who are you to say that witchcraft doesn't exist, merely because you cannot prove it? If you have humanity, who are you to say that it's evil and those who practice it are bad or meanspirited or any other stereotypes linked to witchcraft?
