I read the bit regarding satan’s dispute with the ark angel for Mose’s body. I have always seen this as satan’s attempt to get the body of a prominent person to inhabit so he can become a physical entity and not just a spirit. He will succeed when he enters the anti-christ’s body who was wounded as if dead and rises to rule.
I know what you’re trying to say, but there’s no evidence in the Bible Satan ever inhabited anyone in the past except Judas (John 13:27) and he didn’t have to wait for Judas to die. This tells us two things. First, Satan could inhabit any unbeliever he chooses. And second, he apparently doesn’t feel the need for a physical body most of the time, since the only other person he inhabits will be the anti-Christ (Rev. 13:1-2).
