Jehovah's Witnesses believe that the New World translators "restored" God's name to it's orginal place." But, in all honesty, it was a far stretch for the WTS to put "Jehovah" into the New Testament. If you have access to a NWT reference Bible, here are some things that you should look into: Every time "Jehovah" is inserted into the New Testament, at the bottom of your Reference Bible, you will see J#'s. There are a few appendixes in the back that you should read to begin to understand what that means.
What are these j-versions?
From 1385 A.D. onwards, the New Testament Greek manuscripts started to be translated into certain Hebrew versions with the inclusion of YHWH. It is essential to understand that these have no connection whatsoever with the Hebrew Scriptures or Old Testament manuscripts and were not translated until well over one thousand years after Jesus death.
Basically, those are the ONLY sources out of thousands of manuscripts that the WTS could find to justify replacing "Lord" with "Jehovah." In fact, the interesting thing about those documents, is that, not only are they much later copies translated into Hebrew, but they are actually TRINITARIAN-biased! These documents use the divine name for BOTH God the Father, and for the Son! Yet, the NW translators only borrowed from these documents where they felt is was appropriate (ie: when the J-versions could be used to support the WT pre-conceived ideas).
My point being that, just because the NWT says "Jehovah" doesn't mean that God the Father is REALLY the subject of that passage.
This has allowed the NWT "translators" to obscure the Deity of Jesus. As an example, lets look an the context of the Revelation 1:7-8...... I will still use the NWT, only omitting "Jehovah."
"I am the Alpha and the Omega," says ???, "the One who is and who was and WHO IS COMING, the Almighty."
So who is speaking???
Let’s look at Revelation 22:12-13:
“‘Look! I am coming quickly, and the reward I give is with me, to render to each one as his work is. I am the Al′pha and the O·me′ga, the first and the last, the beginning and the end.’”
Jesus is coming. (Mat 24:30, Mat 26:64, Mar 13:2, Luk 21:2, Rev 1:7, Rev 22:20)
He has His reward with Him. (Isaiah 62:11)
He is the First and the Last. (Rev 1:17,18)
All the evidence points to the speaker in this passage being Jesus, making Him “the Alpha and Omega, the beginning and the end, the first and the last.”
There is only one FIRST and one LAST, and from Isaiah, it is clear that the “First and the Last” is God Almighty!
Thus saith the LORD the King of Israel, and his redeemer the LORD of hosts; I am the first, and I am the last; and beside me there is no God. (Isa 44:6 KJV)
The more you dig, the clearer it becomes that Jesus is not “a” god, but God Almighty, YHWH.
