Yhwh rebelled against his father but was redeemed. Satan rebelled against his father yhwh but will be redeemed.

There's no one before YHWH, outside of him is nothing.

No one existed before your mother.

Book of Enoch says the fallen angels A.K.A. satan, will never be redeemed. God has already passed judgement of death and then eternity in hell against them.

I suspect the beast of Revelation might try to claim he's a new man, he's been saved, God has redeemed him, but that will be a lie. He's doomed. Don't fall for it.

BTW, the word, "satan," has many uses and meanings. It can denote an evil person, a group of evil people, evil itself among other things. Don't get hung up on this idea that Satan is one single solitary person and that his name is Satan.

You might be happy right now, but your name isn't Happy. It's Bob or Tina or Jack or whatever your name is.
