Seems to me you are trying to put human reason to something that Holy Scripture says different. Jesus SON OF GOD! Romans 9:20 read it and just simply accept it.
1 John 4:15 New American Standard Bible (NASB)
15 Whoever confesses that Jesus is the Son of God, God abides in him, and he in God.
Romans 9:20 New American Standard Bible (NASB)
20 On the contrary, who are you, O man, who answers back to God? The thing molded will not say to the molder, Why did you make me like this, will it?
Philippians 2:7 New American Standard Bible (NASB)
7 but [a]emptied Himself, taking the form of a bond-servant, and being made in the likeness of men.
Footnotes:
(a)Philippians 2:7 I.e. laid aside His privileges
By your own admission you deny God as a man Jesus Christ which is the only UN-forgivable sin. Don’t try to understand it just accept it.
