The Trinity is God The Father, God the Son and God the Spirit. All three have no beginning and no end. He is our father too just not in the sense that you’re describing.

Plenty of the Host of Heaven followed Lucifer, I suppose because they agree with your thinking; that God’s plan is abhorrant. But they will be on the wrong side of history and you too if you think you can exist (have eternal joy) without the deity of God. You can believe you’re good and follow moral rules as best you can while creating no victims.... because.... morality; but you’re judging things on mortal standards.

Our souls are eternal, God created them but he’s not a respector of persons and he doesn’t want slaves.

I know that to follow him or go to hell isn’t much of a choice but he’s weeding out the tares and that’s what sinners are, tares to be discarded at the harvest.

Admit you’re a sinner, have faith in Christ that he will wipe our slates clean and be accepted by God I To heaven. Otherwise be a tare and be discarded to hell because no unclean thing can enter into heaven.
