Does the NT clearly identify that the God spoken of by Jesus Christ and Christians is the same Jehovah mentioned in the pre-Christian Scriptures?
Did Jesus identify Jehovah (God in pre-Christian Scriptures) as his own GOD that he speaks of many times?
Did Christian writers identify Jehovah as their God and Jesus' God?
Paul says in Romans 10 that if you confess Jesus is LORD and believe God raised Him from the dead you shall be saved. What does it mean to confess Jesus is Lord? Let’s examine just a couple of passages from Paul and John.
These O.T. passages about YHWH are applied to Christ in the N.T.
Isa 6:1-7
I saw the Lord sitting on a throne, lofty and exalted, with the train of His robe filling the temple.
2Seraphim stood above Him, each having six wings: with two he covered his face, and with two he covered his feet, and with two he flew. And one called out to another and said,
"Holy, Holy, Holy, is the Lord of hosts,
The whole earth is full of His glory."
4And the foundations of the thresholds trembled at the voice of him who called out, while the temple was filling with smoke.
5Then I said,
"Woe is me, for I am ruined!
Because I am a man of unclean lips,
And I live among a people of unclean lips;
For my eyes have seen the King, the Lord of hosts."
6Then one of the seraphim flew to me with a burning coal in his hand, which he had taken from the altar with tongs.
7He touched my mouth
with it and said, "Behold, this has touched your lips; and your iniquity is taken away and your sin is forgiven."
John 12:41-42
These things Isaiah said because he saw His glory, and he spoke of Him. We see that the Apostle John said that Isaiah saw the glory of Jesus in Isaiah 6 for this was the one and only time Isaiah was in the presence of Yahweh.
In Romans 10:9-10, we see that Christians will confess that Jesus is Lord. The context through verse 13 clearly shows that Jesus is the
Lord which all men must call on in order to be saved. Paul quotes from
Joel 2:32 to make his point.Everyone who calls on the name of the Lord will be saved (verse 13). If you read
Joel 2:32 one can see that Paul quoted from this verse.
When we look at the OT passage salvation comes to those who call on the name of YHWH ie...the Divine name of Israel for God. Paul declares it is Jesus upon whom we must call on in order to be saved.
In Philippians 2:9-11, we read that Jesus has a name that is above every name that at His name every knee should bow and that every tongue will confess that Jesus Christ is Lord. Paul bases his statements on
Isaiah 45:23, where we read (By myself I have sworn, my mouth has uttered in all integrity a word that will not be revoked:
Before Me every knee will bow; by Me every tongue will swear .In the context this is clearly YHWH speaking of Himself. He is the Lord who says there is no God apart from Me in verse 21.Paul does not hesitate in saying that every knee will bow to Jesus and every tongue will confess Jesus is YHWH.
It is an indisputable fact that Paul said God bestowed the Name “Yahweh” on Jesus because in
Philippians 2: 9-11 he was quoting
Isaiah 45: 21-24.
This is what Yahweh told Isaiah:
“And there is no other God besides Me, a righteous God and a Savior; there is none except Me. Turn to Me, and be saved, all the ends of the earth; for I am God, and there is no other. 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, they will say of Me, ‘Only in Yahweh are righteousness and strength.’ Men will come to Him and all who were angry with Him shall be put to shame.”
Isaiah 43: 11- Yahweh said that He is our only Savior- Even I Am Yahweh and there is no other Savior besides Me. This verse is very clear as to its meaning.
We see that Yahweh is the Name God bestowed on Jesus and it is Yahweh which is the Name that is above every name and it is Yahweh to which every knee will bow. There is no mistaking that Paul declares in his epistles that Jesus is the Yahweh of the Hebrew Scriptures. Jesus is our Lord Yahweh in the New Testament as well as our Savior. These were the specific names that were Gods alone in the Old Testament.
hope this helps !!!
