I know who Jesus is, and who he said that are his. HE said they that endure till the end, the same shall be saved. Paul said that he didn't want to preach the word of God, and end up a cast away. What do you think a castaway is? It's rejected.

The word 'and' that you kept bolding is 'even' the throne of God 'even' that is, the Lamb. God (Spirit) bought the church with his own blood, again this is a first-person pronoun. It's not referring to anyone else.
But a spirit doesn't have blood, so he made a body from the foundation of the world Jesus Christ, the one who created all things. The name above every name in heaven and earth. That's not modelism, it's what the bible says.
That would be a singular pronoun, or equal to one.
Same word used for the Devil AND Satan, there are not two of him are there. And by the way he is also one spirit that doesn't operate without a body.
This is my last post there's nothing more to say.
