Nowhere does the Bible mention that Christians should call themselves by the name that God gave to the people of Israel, which significantly does not appear once in the basic Greek text of the New Testament. We want to be witnesses of Jesus and simply be called Christians - as Jesus commanded and as it was also ordained by divine providence (Acts 1:8; 11:26).
A Christian is a follower of Jesus Christ.
Jesus Christ is a witness of his God and Father Jehovah. (John 20:17;16:27;17:7,8)
To follow Jesus would mean too also be a witness of Jehovah.
[ 5 and from Jesus Christ, “the Faithful Witness,” “the firstborn from the dead,” and “the Ruler of the kings of the earth.”]
[ 16 Jesus, in turn, answered them and said: “What I teach is not mine, but belongs to him who sent me. 17 If anyone desires to do His will, he will know whether the teaching is from God or I speak of my own originality. 18 Whoever speaks of his own originality is seeking his own glory; but whoever seeks the glory of the one who sent him, this one is true and there is no unrighteousness in him.]
[49 For I have not spoken of my own initiative, but the Father who sent me has himself given me a commandment about what to say and what to speak.]
[28 Jesus then said: “After you have lifted up the Son of man, then you will know that I am he and that I do nothing of my own initiative; but just as the Father taught me, I speak these things.]

What allowed these people to be JWs to begin with?
They said this:
We strongly recommend that you look up the biblical passages quoted and check for yourselves whether this is really the case (Acts 17:11).
Firstly, it must be noted: The critical examination of special teachings is not apostasy, but a Christian commandment (1 John 4:1, 1 Thess. 5:21).
These Scriptures have always been there and said the same. If they followed that from the beginning they would never have become JWs.
And here:
We therefore hereby declare that we no longer wish to be known as Jehovah's Witnesses.
We ask for written confirmation.
Why do they request from a fake/baseless religion to tell them what they are or not?
