I have been searching pro and anti arguments for trinity, and found out there are anti-trinitarians who believe Jesus did not preexist before his human life. And I am thinking, it kind of makes sense.
What if Yahweh created a second Adam. He would have really been the only begotten son of God, and His firstborn.
And this would have been proof for satan that it is possible that a perfect human being can remain loyal to God, that His creation was not flawed.
If an angel came from heaven to be "incarnated" or "transferred" in a human body, that would have not proved that real humans were capable of being loyal.
But if a second Adam (Jesus) was created, wow, there was no guarantee of the outcome. That would show that God had trust in His human creation, despite everything, and that He really took a risk with Jesus.
Plus, If we think about it, in the old testament there were so many times when the second child was put before the first one. Jacob before Esau, Abel before Cain, Ephraim before Manaseh. This must have been prophetic.
And Jesus was the perfect man who was loyal to God till the end, unlike Adam. - this showed Satan that a man can be loyal and also offered the necessary sacrifice that was needed for others to be saved.
And God rewarded Jesus by not only resurrecting him, but by making him a new glorified creation. ( I also believe that the jw story that God made Christ's body dissapear and then made him appear in different human bodies to the disciples is just weird)
My personal opinion is that God created a new type of being that somehow can travel between earth ad heaven, Jesus was the first one and the other christians will be transformed in the same type of being at the rapture. And eventually I think all people in the everlasting Kingdom will be (after the 1000 years). - Speaking of "making all things new"! I think this also has to do with the sacret secret (revealed only after Acts and of which Paul says that if Satan knew, he would not have crucified Jesus) that the jw's are not getting at all - the new creation seams to them so amazing that they think it is limited in number - 144000. They are so wrong! All true christians will be like that.
So if from the first Adam we are linked by flash and he transmits us death, to the second Adam, Jesus, we can be linked by FAITH and he transmits us everlasting life! - Romans 10:9,10 and Titus 3:5 ; 2 Corinthians 5:17
I am still researching this subject. What do you think?
