Under which name must Christians be saved? Well according to WTS it is Jehovah. This is written in Joel 2: 32 (read NWT). 32 And it must occur that everyone who calls on the name of Jehovah will get away safe; for in Mount Zion and in Jerusalem there will prove to be the escaped ones, just as Jehovah has said, and in among the survivors, whom Jehovah is calling.” But this contradicts Acts 4: 12, I posted also the previous verses so you can see the verse is talking about Jesus. Then Peter, filled with holy spirit, said to them:
“Rulers of the people and older men, 9 if we are this day being examined, on the basis of a good deed to an ailing man, as to by whom this man has been made well, 10 let it be known to all of YOU and to all the people of Israel, that in the name of Jesus Christ the Naz·a·rene´, whom YOU impaled but whom God raised up from the dead, by this one does this man stand here sound in front of YOU . 11 This is ‘the stone that was treated by YOU builders as of no account that has become the head of the corner.’ 12 Furthermore, there is no salvation in anyone else, for there is not another name under heaven that has been given among men by which we must get saved.”
But if you read another Bible translation f.x New American Standard Bible, then the scripture from OT are consistent with Acts 4:12 in NT.
Off course when the WTS talks about Jehovah as the saviour, then they never mention Acts 4:12. The NT shows many times that Jesus is the saviour.
