my husband still believes the Bible is infallible.>>.Then my suggestion would be look up sites that show where the many bible Scriptures contradict each other ,and their are many .
That should undermine his faith in the Bible being infallible.unless he is a total hopeless lost cause .
But their is more you can do : The WTB&TS published a publication "The kingdom Interlinear Of The Christian Greek Scriptures" a word for word translation of the text the WT used for the N.W.T. of the Christian Greek Scriptures .
Nowhere in that translation in Greek does the Tetragrammaton the four Hebrew letters representing Gods name JHVH/YHWH in either Hebrew or Greek.
Therefore for the Watchtower to put the name Jehovah in the Christian Greek Scriptures is dishonest .
Also, nowhere in the Christian Greek Scriptures are Christians told to be witnesses of Jehovah ,nowhere.!.... however their are upwards of 20 times where Christians are to be witnesses of Jesus Christ in the Christian Greek Scriptures.
And more pointedly the Bible states that "in the name Jesus every knee should bend (in worship ) of those in heaven and those on earth and those under the ground"
Notice ! not in Jehovah`s name but in Jesus name every knee should bend in worship and that God exalted him to a superior position and kindly gave him ( Jesus ) the name that is above every other name .( including the name Jehovah ) Phil.2 :9-11
