There is no divine name. Jesus NEVER addressed his God by a personal name. He primarily addressed him as "Father."
Neither did his disciples address The Most High God by a personal name.
It was his Fathers REPUTATION (Good name) that Jesus focused upon, not a PERSONAL name.
Names such as Jehovah or Yahweh are not in the Bible and Jesus never spoke such names. They were added.
In the three languages of the Bible: Hebrew, Aramaic and Greek there is no letter J.
There is no letter J in Latin either.
In fact, if one looks at the original King James Bible of 1611 you will not see the letter J in any name.
At Psalms 83:18 for example you see:
That men may knowe, that thou, whose name alone is IEHOVAH: art the most High ouer all the earth.
And this is not fully correct because their are no vowels in the Hebrew language. Thus it would be IHVH.
With regards Jesus his name is wrong to. He would not have been called Jesus but something like Iesus (Isis). See John 1:17 in the same Bible.
The bottom line is that Jesus (Iesus) NEVER used a personal name. The WTBTS added the name to the Greek Scriptures because THEY felt it should be their. THEY decided for everyone else that the name would be Jehovah. (Again no J in the Hebrew language).
Like ancient Israel, we do not know God's personal name. Why? Because it is a PERFECT name and we are IMPERFECT creatures.
All we know is that he is a good God. He has a good reputation (name).
His name has not been revealed to us yet.
At Revelation 3:12 Jesus even says that he WILL THEN "write upon him the name of my God ..."
When that name is revealed, what a name it will be! It will be a "proven" and tested name. No one will be able to deny that it is God's name. What a glorious name it will be!
Sadly, the WTBTS and others have move presumptuously and gave us a name. It is a false name!
The WTBTS and others have not allowed God to reveal himself to us.
When God said to Adam when he was hiding from him, "Who told you that you were naked?" He would say to the many, "Who told you that my name is Jehovah? I have not revealed my perfect name to you and neither has my son."
