Let's try and get one thing out.
This is going to be a dictionary meaning of what it would be IF God exists (whether you choose to believe or not)
You can't even begin to try and understand God with our level of thinking. God is infinite. He is Omnipotent, Omniscience, Omnipresence. He exists beyond the realm of Logic and Understanding. He bends the Laws of Physics and Mathematical Properties to his whim. That's what Infinite Power is. No boundaries.
Now, if you're scared, I guess it's completely acceptable to be. But that fear basically shows that you have faith. You don't have to follow the Religion. Abraham (Considered the Father of Religions of the Book) never had any of the books now. He just believed and did what God asked of him. Pray, believe, do good in life, and do not do wrong. The books have been created as to help people with guidelines and to restore faith so they would not deviate.
If there's one thing I ask of anyone, it's to not ask me "Why would God this?" or "Why would God that?" because I don't have the answers, only the belief
