Jesus saves but what does he saves us from?
Jesus brings us back into the presence of God just like he did for Abraham, Isaac, Jacob, and the other prophets. Do you know not realize that those who lived on Earth continues in a physical form? When Jesus was transfigured on the mount, Moses and Elijah like angels were there, were they not? This is evidence of them minimum that the righteous will exist eternally in the next life with God.
Also, do you not know that first for references of Angel in Hebrew in the Old Testament literally translates to Children of the Most High God? If Moses and Elijah became like Angels or the Children of God then what of others who follow Jesus Christ with all their hearts? Does it not say in Romans that we will become joint-heirs with Christ? Also, what does it say in Revelations with happen to all the righteous on the day of final judgement? Others may answer these questions, but alteast Mormons try to answer these questions with good explanation found within their theology.
You have a serious lack of understanding on the Bible and Angels.
Angels were created seperately and have no decendants.
As for their appearance, all the redeemed have a new Body, but NOWHERE is there a mention of God the father having a physical form, or that he had a beginning
None of what you mentioned had anything to do with the false doctrine of me, you, Jesus and Satan being literally brothers.
