Jesus Christ is Jehovah, the God of Abraham, and Isaac, and Jacob.
God in the Old Testament said He will be the one to save Israel from their sins to have a spiritual relationship with Him, and said there is no other Savior beside Him.
In the Old Testament God said He will speak to the Jews, and reveal a new name to them.
Jesus said to Philip that if he has seen Him he has seen the Father, for the words He speaks are not His own, but the Father that dwells in Him, He does the works.
Jesus is the name that is above all names, not only in this world, but in the world to come, which Jesus is above the name of Jehovah.
God's name represents His character in dealing with people, so the names known to us that God has is only a revelation of what God wants us to know of Him for what he wants for us in blessing towards us.
So the name of Jehovah, and Jesus, only represent God's character in relation to humans, and would not represent God in all His attributes as God for He can only know that.
For to actually know the name of God to represent God in His fulness of wisdom, and power, and all His attributes, could never be known to us, and would not be revealed to us, for we could never know all that is God in all His fulness as God.
So Jesus can be above the name Jehovah, for Jehovah is not the name of God to represent Him in His fulness, but only a name to reveal what He has given us in blessings from Him.
We could never know all what God knows, and never have all His power, and could not be omnipresent, so we could know God's name in the fulness of Him.
Which the Bible says that Jesus has a name that no man knows, and we could never know that name.
The name of Jehovah was not revealed to the Jews until God was ready to take the Jews out of Egypt, which the name represents physical deliverance, and physical blessings.
The name Jesus was not revealed to the Jews until God was ready to give salvation, which the name represents spiritual deliverance, and spiritual blessings.
So the name Jesus is above the name Jehovah for the blessings and gifts from God are far greater than what the name Jehovah offered.
Jesus would have to be the God of Abraham, and Isaac, and Jacob, if it is above the name Jehovah.
Solomon said how can God dwell in a temple made with hands when the heaven and the heaven of heavens cannot contain God, and He said My name will be there.
