Is it true that Jesus is claiming to be YHWH with these verses. Let us examine.
Do we assume that Jesus claimed to be YHWH as others already have because YHWH claimed to be the Alpha and Omega in Isaiah 44;6?
Do we assume that Jesus, by using this title is claiming that this was also thus - He is eternally Jehovah from the first to last?.
Do we assume that in Rev 22:13, there is an expanded meaning, "I am the Alpha and the Omega, the First and the Last, the Beginning and the End."? - lest there be any doubt!
It is doubtful if Jesus really claimed to be YHWH of the OT because then that would mean that he is the Father. If one believes that Jesus is not the Father and the Father is not Jesus but assumes that Jesus is the YHWH of the OT, how is it that the prophets and apostles of God do not believe and teach that Jesus is the God of the OT. On the contrary, Jesus never claimed to be the God of the OT as Mark 12:26-27 show. Jesus could have said "have ye not read in the book of Moses in the place concerning the burning bush, how I spake to him saying.." and Acts 3:13 show that Jesus was not the God of the patriarchs.
Mark 12:26-27 ASV
But as touching the dead, that they are raised; have ye not read in the book of Moses, in the place concerning the Bush, how God spake unto him, saying, I am the God of Abraham, and the God of Isaac, and the God of Jacob? He is not the God of the dead, but of the living: ye do greatly err.
Acts 3-13-15 ASV
The God of Abraham, and of Isaac, and of Jacob, the God of our fathers, hath glorified his Servant Jesus; whom ye delivered up, and denied before the face of Pilate, when he had determined to release him. But ye denied the Holy and Righteous One, and asked for a murderer to be granted unto you, and killed the Prince of life; whom God raised from the dead; whereof we are witnesses.
Studying Isaiah 44: one will find that the speaker Isaiah 44: is not Jesus. Isaiah 44:24 will show that it is YHWH. If Jesus is God from the beginning, how is it that he was not involved or mentioned by the prophets and patriarchs in the Old Testament in their dealings with their God in the Old Testament.
Examining the verse in question the word "first" here was translated from the word "protos' and not "alpha" as shown on Bible hub. The context also reveals that Jesus died. This makes it clear that this verse cannot be used as a reference to God because God has never died. Acts 3:13-15 further reinforces that Jesus was never God from the beginning as the apostles and their forefathers taught. On the contrary, Jesus was God's servant and it was his God who resurrected him.
First
πρῶτος (prōtos)
Adjective - Nominative Masculine Singular
Strong's 4413: First, before, principal, most important. Contracted superlative of pro; foremost.
Going by the title confusion trick used by some, if the first and the last is YHWH, then Revelation 1:18 show YHWH was dead. However, this is impossible according to the scriptures. Habakkuk 1:12; 1 Timothy 6:16.
When the title Alpha and Omega refers to God. He is where creation begins and ends. Isaiah 48:12-13. Isaiah 41:4
Habakkuk 1:12 ASV
Art not thou from everlasting, O Jehovah my God, my Holy One? we shall not die. O Jehovah, thou hast ordained him for judgment; and thou, O Rock, hast established him for correction
1 Timothy 6:16 ASV
who only hath immortality, dwelling in light unapproachable; whom no man hath seen, nor can see: to whom be honor and power eternal. Amen.
Isaiah 48:12-13 ASV
Hearken unto me, O Jacob, and Israel my called: I am he; I am the first, I also am the last Yea, my hand hath laid the foundation of the earth, and my right hand hath spread out the heavens: when I call unto them, they stand up together
So, was it the eternal, immortal and Almighty God who declared "and the Living one; and I was dead, and behold, I am alive for evermore, and I have the keys of death and of Hades" or was it someone who is not the immortal, eternal and Almighty God?
