Jesus is YHWH(Jehovah)
In Jesus’ day, it was assumed by Jews that there was only one God—Jehovah (YHWH).
[1] Isaiah 44:6 condenses this Jewish understanding when it says, “Thus saith the Lord [Jehovah] the King of Israel, and his redeemer the Lord [Jehovah] of Hosts; I am the first, and I am the last; and beside me there is no God.” But the New Testament added a new dimension when it ascribed divinity to Jesus (see John 1:1, 14; 20:28) or when it recorded that persons worshiped Jesus (see Matthew 2:2, 11; 28:17).
Christian theologians since the Council of Nicea have understood these passages through the doctrine of the Trinity, which states that there are three persons in the Godhead who are of one essence or of one nature. In this light, the mystery of God revealed in the incarnation of Jesus, according to traditional Christian thought, is that the Father (Jehovah) has a Son (Jesus). Thus, whatever can be said of Jehovah can also be said of His Son, who is a member of the Godhead, who is one with His Father, and who shares the nature of the Father.
