Maybe by just pointing out the obvious.
Jehovah`s Witnesses claim to be Bible based in Scripture.
Philipians 2:9- 10 says God gave Jesus a name that is above every other name and that every knee should bend of those in heaven on earth and those under the ground.
{That obviously excludes the name Jehovah that is not found in the Christian Greek Scriptures and neither is the Tetragrammaton or its Greek equivalent.
Also ,at Acts 11: "it was first in Antioch that the disciples were by divine providence called Christians "
Note : "by divine providence" and "they were to be called Christians"
Not Jehovah`s Witnesses.
And even after Isa,43 : 10- 12 ,the Jews never ever identified themselves as Jehovah`s witnesses even though that scripture was meant for them primarily.
Secondly: Jesus never identified his followers as Jehovah`s Witnesses
In conclusion Acts and Phillipians clearly show that Jesus is the one name to put your trust and hope in as that is the name GOD gave to Christians to put faith in.
