You can’t sell your soul to him… he doesn’t have anything to give you in return except empty promises. However, that hasn’t stopped some people from trying.
As for your powers, make a video game or read a comic book. I’ve dabbled with magic and divination in my old life. As a Christian I can tell you it’s all empty and counterfit. None of that stuff is true power. If you want to cause chaos and scare normal folk become a true Christian in the name of Jesus.
I’ll tell you what, nothing freaks people out like an Anti-Christ giving his heart over to the Lord. Everyone “normal” person I knew were scared of me and their lives, as well as mine, were never the same.
True power is found in the name of Jesus!!!
