You reject Jesus, so whatever power you think you have is most certainly demonic.
It’s like you didn’t bother to read anything in the Bible and arrived at a conclusion about Christianity based on flawed understandings and caricatures spewed by atheists.
You’re worshipping someone and it’s not God. Bold move.
“You certainly will not die! God knows well that when you eat of it your eyes will be opened and you will be like gods, who know good and evil.”
