Matthew 1:23 confirms that the prophecy in Isaiah 7:10-14 was fulfilled in Jesus because Jesus is "Immanuel” which is translated as “God with us." Thus, Isaiah 9:6 is a prophecy predicting that the name of the child born and son given would be called the same name as the "Mighty God" and "Eternal Father” (John 17:11, Philippians 2:9, Heb. 1:4). This is why the prophet Jeremiah wrote that the Son "shall be called (future tense), Yahweh our righteousness" (Jer. 23:5-6 – An alleged God the Son should have always been called Yahweh). And this is why Psalm 118:14 says, "Yahweh is my strength and my song, He also has BECOME MY SALVATION."
When we read the entire chapter of Psalm 118 in context, we find that Yahweh became our salvation as Jesus.
"This is the gate of Yahweh (Jesus is the door); the righteous will enter through it. I shall give thanks to You, for YOU HAVE BECOME MY SALVATION. The stone which the builders rejected has become the chief cornerstone. This is Yahweh's doing. It is marvelous in our eyes (Psalm 118:20-23)."
Jesus cited Psalm 118:23 (in Matthew 21:42, Mark 12:10-11, and Luke 20:17) referencing himself which proves that Jesus is Yahweh who has become our salvation by His own Holy Spirit who descended upon the virgin to become the Christ child (Luke 1:35). Thus Jesus proved that He is Yahweh God incarnate as the Messiah when he said, “Have you not even read this scripture: The stone which the builders rejected, this became the chief corner stone; this came about from the LORD, and it is marvelous in our eyes? And they were seeking to seize him, and yet they feared the people …” Mark 12:10-12 NASB
The Pharisees not only perceived that Jesus had spoken the previous parable against them, but they were obviously familiar with the context of Psalm 118 which says that Yahweh would become our salvation. Thus, when Jesus cited Psalm 118 about himself, the Pharisees became enraged at Jesus and sought to kill him because they assumed that he had also spoken blasphemy by claiming to be Yahweh Himself. Therefore the Pharisees could not accept the fact that Jesus is Yahweh who became our salvation as “God with us” as a true man.
The Name of Jesus in Hebrew means YAHWEH SAVES
Philippians 2:10-11 informs us that all of humanity will one day bow to Jesus and confess him as LORD. But Isaiah 45:23 shows that the Father is the speaker (cited in Philippians 2:10-11) who says that all of humanity will bow and swear to Him (the context prove the Father) as LORD (YAHWEH).
Philippians 2:9-11, "God highly exalted him, and bestowed on Him the name which is ABOVE EVERY NAME [Yahweh is the only Name above every Name], 10 so that at the name of Jesus [Yahweh Saves] EVERY KNEE WILL BOW, of those who are in heaven and on earth and under the earth, 11 and that EVERY TONGUE WILL CONFESS that Jesus Christ is Lord [Yahweh is translated as Kurios throughout the Greek Septuagint], to the glory of God the Father."
Notice that the context of Isaiah 45:21-23 shows that Yahweh God is the speaker Who says,
“Declare and set forth your case; Indeed, let them consult together. Who has announced this from of old? Who has long since declared it? Is it not I, the LORD [YHWH]? And there is no other God besides Me, A righteous God and a Savior; There is none except Me. 22 “Turn to Me and be saved, all the ends of the earth; For I am God, and there is no other. 23 “I have sworn by Myself, The word has gone forth from My mouth in righteousness And will not turn back, That TO Me EVERY KNEE WILL BOW, EVERY TONGUE WILL SWEAR allegiance."
Anyone who compares the context of Isaiah 45:23 with Philippians 2:9-11 should clearly see that to bow the knee to Jesus and to confess him as Lord (the context proves at the end of this age) is to bow the knee to the Father and confess that the Father is Lord. Hence, all bowing and confession to Jesus as Lord (at the end of this age) is all “to the glory of God the Father” alone rather than to the glory of two other alleged coequal members of a Trinity (Isaiah 45:14-15 says that men “will bow” to the Messiah saying, “surely God is in you, there is none else, there is no other God. Truly you are a God who hides Himself, O God of Israel the Savior”; Zechariah 14:9 “And Yahweh shall be King over all the earth; in that day there shall be One Yahweh and His Name One”). This is not what we would expect if the Son is a coequally distinct true God Person beside the Father. For why would bowing the knee to Jesus and confessing him as LORD be “to the glory of God the Father?” If the Son is a coequally distinct true God Person, then the Son should also have His own divine glory and dignity rather than just the Father.
The words of Isaiah 45:23 in context prove that Yahweh God the Father is the speaker who says, "The word (Jesus is the word/logos in John 1:1, 14) has gone forth from My Mouth (the Father's mouth) in righteousness and will not turn back, That TO ME EVERY KNEE WILL BOW, EVERY TONGUE WILL SWEAR ALLEGIANCE."
The context of Isaiah 45:23 proves that the Father is the speaker who said that His word (the Father’s word is Jesus – John 1:1, 14; Rev. 19:13) “has gone forth” from His “mouth” (i.e. the Father’s mouth). Since the Son of God is clearly the word that has gone out of the Father’s mouth, it is nonsensical to believe that a timelessly coequal true God Person could have gone forth from the Father’s anthropomorphic mouth while being timeless and coequal. Therefore the Son of God existed as the logos of God the Father (as the Father’s expressed thought) that was later made flesh to become the Christ child.
Since Philippians 2:10-11 cites Isaiah 45:23, we know that to bow and confess Jesus as LORD is to bow and swear "TO ME" [TO THE FATHER]. John 14:24 proves that Jesus is the Father's word (logos) who "has gone forth from" the Father's "mouth", so when every knee bows and confesses Jesus Christ as LORD, we know that all are bowing and confessing Jesus Christ as YAHWEH because the deity in Jesus ("God with us" as a man) is the deity of the Father who gets all of "the glory". For if Jesus was a coequally distinct divine person, then the scripture would say, "to the glory of the Son and the Father." The Father gets all the glory because the Son is "the brightness of His (the Father's) glory and the express image of His (the Father's) Person" as a fully complete human person (Heb. 1:3).
Furthermore, how could the Son as the Son have always existed as an alleged Yahweh God the Son Person while the Name of Yahweh was “bestowed on Him” at a specific point in time? Can God as a true God Person be “given” or “bestowed” the Name Yahweh while always eternally existing as a timeless and coequal true God Person, distinct from the Father? Therefore the Trinitarian idea of a timeless God the Son cannot harmonize with Philippians 2:9 and other scriptures which state that the Son was given the Father’s Name in time (Yahweh Saves – John 5:43; John 17:11; Jer. 23:6).
Hebrews 2:14-17 proves that the "He" who "partook of flesh and blood" is Yahweh who has become our salvation by being made as a fully complete human son in order to save us. Hence, the Father’s own Name (Yahweh) was given to the Son when the angel gave the Son’s name to Joseph (Matthew 1:21). Therefore the Holy Spirit of the only true God miraculously became a man within the virgin in order to “save His people from their sins” (Matthew 1:20-23, Luke 1:35, 1 Tim. 3:16).
