The searcher points out that their are about 30 scriptures in the New Testament that admonish followers of JC ,to wtness about him and for him .
Their is not one (1 ) scripture in the New Testament that admonish followers of JC to witness about Jehovah
Jesus never used the name Jehovah , nor did any of the Apostles ,and not one of his Disciples.
The KI ,word for word translation of the Christian Greek Scriptures ,published by the WTB&TS ,does not have the Tetragrammaton representing the name Jehovah anywhere in it , therefore that name Jehovah does not belong in the New Testament.
It`s an unauthorised addition to the Bible
If knowing and using the personal name of God was of such importance , you would think that Jesus ,the Apostles ,and his Disciples would have made a big issue abut it ,they never used this name once ,none of them
As for Isa.43:10-12 , the Israelites never identified themselves as Jehovahs Witnesses in the 100`s of years before JC ,and that scripture was directed specifically to them , and JC never rebuked them for not identyfing themseves as JW`s.
