Nothing in the Bible says that God is truly omnipotent; the Bibile itself references multiple times the existence of Satan, the evil, which ruins the existence on Earth and pushes people to commit sins.
Atheist here. I have a co-worker who says the world is ultimately just and so we don't have to really work at improving things because the difference will be paid off in the afterlife.
Yes, the bible says that God created Satan, an entity which had free will and was "good".
Like the human, the entity could also do sinful things thanks to the fact that he had free will.
Infact, Satan turned "bad" but Lucifer’s sinful pride cost him his place in paradise.
But if he’s so powerful that he can stick him in the centre of the earth, why couldn’t he put him in a place where he actually wasn’t able to tempt humanity?
