How the name came about

Accepting the Responsibility
What an honor it is to bear the name of the only true God, the Sovereign of the universe! But with that name goes responsibility. It is a responsibility that other religious groups do not want. As Brother Rutherford said in his discourse: “Happy are they that can take a name that nobody under the sun wants except those who are wholly and unreservedly devoted to Jehovah.” Yet, how fitting it is that Jehovah’s servants bear God’s personal name, that they make it known, and that it be prominently associated with the proclamation of his purpose!
Any group or individuals that speak in the name of Jehovah put themselves under obligation to convey his word truthfully. (Jer. 23:26-28)

When he was eighty-eight years old A. H. Macmillan attended the “Fruitage of the Spirit” Assembly of Jehovah’s Witnesses in the same city. There, on August 1, 1964, Brother Macmillan made these interesting comments on how the adopting of that name came about:
“It was my privilege to be here in Columbus in 1931 when we received . . . the new title or name . . . I was amongst the five that were to make a comment on what we thought about the idea of accepting that name, and I told them this briefly: I thought that it was a splendid idea because that title there told the world what we were doing and what our business was. Prior to this we were called Bible Students. Why? Because that’s what we were. And then when other nations began to study with us, we were called International Bible Students. But now we are witnesses for Jehovah God, and that title there tells the public just what we are and what we’re doing. . . .
“In fact, it was God Almighty, I believe, that led to that, for Brother Rutherford told me himself that he woke up one night when he was preparing for that convention and he said, ‘What in the world did I suggest an international convention for when I have no special speech or message for them? Why bring them all here?’ And then he began to think about it, and Isaiah 43 came to his mind. He got up at two o’clock in the morning and wrote in shorthand, at his own desk, an outline of the discourse he was going to give about the Kingdom, the hope of the world, and about the new name. And all that was uttered by him at that time was prepared that night, or that morning at two o’clock. And [there is] no doubt in my mind—not then nor now—that the Lord guided him in that, and that is the name Jehovah wants us to bear and we’re very happy and very glad to have it.”
So there you have it, yes it's easy to see the Lords hand behind J.F Rutherfords endeavours.Thank you Jesus!
