Hi cgaviria,
I perceive you are studying, and seeking the truth, and not so concerned what man thinks.
It is more then easy to prove Jesus could not be God, but not easy to believe, as I'm sure you have found as well sharing the word.
What I would like to show though, is that Jesus had his beginnings at birth, and not before he was born, as before the foundation of the world, because there is no place where it is said Jesus created heaven and earth, but he is before the new creation, the foundation of, the beginning of, the firstborn [from the dead] over all creation. He is before all things because all things consist in him, for he is high priest, chief king, in the kingdom of many priest and kings, this list could go on, for nothing could be without him towards the new creation, and the ages to come. - I am referring to Heb. 1:2 “by whom also he made the worlds (165. aión – ages)” As it also speaks in Eph 2:6-7 ...and made us sit together in the heavenly places in Christ Jesus, that in the ages to come..., and compare to Col 1:15-18 For by (1722. en – in) Him all things were created. We have this age, then age of 1,000 years, end of which all enemies are put under his feet, and then when he hands over the Kingdom to his God and Father.
Psalm 22 is speaking of Christ, and you will notice it is the spirit of Christ speaking, I'm referring to words on a page, not a person. This is the Psalm which we know speaks of Christ where it says, Jesus speaking “My God, my God, why have you forsaken me”[Psalm 22:1].
...then... “they shake the head, saying, he trusted in the LORD, let Him rescue him; let Him deliver him, since He delights in him!” [Psalm 22:7,8].
Now if you will notice the next two verses 9 and 10 it says, “But You are He who took me out of the womb; You made me trust while on my mother's breasts. I was cast upon You from birth. From my mother's womb You have been my God.” [Psalm 22:9, 10]
From the womb God has been Christ's God, not before. John 1:14 ...the word (3056. logos - a word, being the expression of a thought; expressing the thoughts of the Father through the Spirit) became flesh, not a person became flesh, and 1 John 1:1 the word (3056. logos) of life, which they handled and seen.
Then Isaiah 45, you will notice also speaks of Christ. This is what verses 4 and 5 have to say “For Jacob My servant’s sake, and Israel My elect, I have even called you by your name; I have named you [compare with Luke 1:31 “...and shall call his name Jesus.”; or Matt 1:21], though you have not known Me. 5 I am the Lord, and there is no other; there is no God besides Me. I will gird you, though you have not known Me.” - God put a hedge around him, that he may prosper, then allowed the hedge to be removed, taking all from him, then allowing him to suffer greatly.
This states when God named Jesus, Jesus did not know God before this time.
Angels, or spirits are immortal, they cannot die, Jesus died. Jesus had the fallen nature of his mother, for he was tempted, but had the character of his Father, being holy being born of the holy spirit; this is how he overcame the flesh, temptation. He did not receive the nature of his Father until after his resurrection (Heb 1:3-4) when he received immortality, and destroying sin in the flesh, now no longer tempted by sin in the flesh.
God's Spirit is His power and His word [compare Luke 1:35 and John 1:14; Ephesians 6:17 – in the Greek “word (neuter) - 4487. rhéma - a spoken word” points to “Spirit (neuter),” not to “sword (feminine)”, so in other words it could read, “...and the sword of the word...”].
Sometimes to understand the New Testament, we must turn to the Old Testament. The Berean Jews searched the Old Testament scriptures to see if what the apostle taught were true. So, what the apostles taught must be in the O/T, as Paul declared in Acts 26:22-23.
