A few things you should know about witchcraft...

I am seeing far to many posts and videos about how you can summon angels or talk to them and I want to make a few things very, very clear. The only way you can do either of those is through God. You pray. Anything else is demonology.
Witches use energy to preform spells. They get this energy by sacrificing something. They change one form of energy to another and in doing so transfer that energy to the spell or demon they are summoning. Witchcraft and demons are their strongest at night, they hate the light, they still work in it but it extremely weakens them. Notice the increase in fires in America? Yeah there's a reason for that, changing energy. These energies are shared through lay lines. Ever notices the most satanic places have obelisks? This is because these are the places all the lay lines tend to meet hence where the strongest magicks can be preformed. Don't be fooled, God is the only way.

This may sound funny for some, but I found out that I can do magic. So I started learning about so called white magic. Then I realized exactly what you said above. There's no white magic. There's only God doing his thing through us and there's black magic.
