The Mind Is Everything. U R What U Think
The first of your assertion concerning early Christians is not correct. They did believe Jesus was God.God did not incarnate in original Christianity either....apostasy caused corrupt humans to adopt that belief (stolen from non-Abrahamic religions.) The God of Abraham does not need to personally pay the ransom for mankind for two reasons....
1) God is immortal and cannot die. Mere humans cannot kill God.
2) If God came to earth as a human, then he would not be the equivalent of Adam.....who was a creation of God. it would be an overpayment equivalent to paying a kidnapper 100 trillion dollars when he only demanded a million.

And that's not an accurate description of the second Adam at all.
1 Corinthians 15:“since death came through a man, the resurrection of the dead also comes through a man. For as in Adam all die, so in Christ all will be made alive” (verses 22-23)."
