No where in the New Testament / Christian Greek Scriptures as JW`s like to call it are the followers of Jesus christ called upon to be witnesses of Jehovah God ,nowhere not one scripture .
However their are something like 20 or more scriptures in the Christian Greek Scriptures / NT that specifically call upon Christians to bear witness to, for or about Jesus Christ ,and not Jehovah.
And the NWT of the Christian Greek Scriptures that they base their text on does not contain the four Hebrew letters the Tetragrammaton nor does it contain any four Greek letters representing god`s name .
The Kingdom Interlinear Translation of the Greek Scriptures revised by Westcott and Hort (1948 reprint) a literal word for word translation into English.1969 edition printed by the WTB&TS .And nowhere does the name / word Jehovah exist there.
