The Jehovah's Witnesses have never caught on to the fact that Jehovah was the pre-existent Jesus.
Whether you believe in the fall of man and the Garden of Eden or not, the entire idea behind the fall is that once Adam and Eve fell, they needed a mediator. Having cut themselves off from Elohim (Gods), the mediator had already been chosen — and that mediator was Jehovah, the God of Israel who was born into mortality as Jesus of Nazareth. That's why He spoke as Jehovah in the Old Testament and to John in the book of Revelation. Thus He had the same titles and the same authority, and in the New Testament it reads: “Then the eleven disciples went away into Galilee, into a mountain where Jesus had appointed them. And when they saw him, they worshipped him: but some doubted. And Jesus came and spake unto them, saying, ‘All power is given unto me in heaven and in Earth. Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you always, even unto the end of the world. Amen.’” (Matthew 28)
At the time Jesus said this, He had been crucified and resurrected. Now He had all power in heaven and Earth. No angel could attain this kind of power, intelligence and glory, for Jesus now had fulfilled His destiny. The scriptures state that Jehovah is the judge of mankind and all nations. And John confirmed that “The Father judgeth no man, but has committed all judgment to the Son.” (John 5:22) Thus, Jehovah and Jesus are one and the same. This becomes even more apparent in the book of Revelation: “I am Alpha and Omega, the beginning and the ending, saith the Lord, which is, and which was, and which is to come, the Almighty.” (Revelation 1:8) Here He is called “the Lord” and the “Almighty.” And throughout the book He is clearly associated with the God of the Old Testament.
Now hear the words of the prophet Zechariah, who writes that when Jehovah comes with power and glory during the battle of Armageddon: “And they shall look upon me whom they have pierced, and they shall mourn for him, as one mourneth for his only son, and shall be in bitterness for him, as one that is in bitterness for his firstborn.” Then he writes: “In that day shall there be a great mourning in Jerusalem, as the mourning of Hadadrimmon in the valley of Megiddon.” (Zechariah 12). Then in Revelation, John writes: “Behold, [Jesus] cometh with clouds; and every eye shall see him, and they also which pierced him: and all kindreds of the earth shall wail because of him.” (Revelation 1)
Clearly, Jehovah and Jesus are the same. In the Old Testament, Jehovah will come and 1) the Jews will see Him who their fathers “pierced” and 2) [the Jews] shall “mourn for him as one mourns for his only son.” And they shall be “in bitterness for him as one that is in bitterness for his firstborn.” How the Jews could miss this is remarkable; how the Jehovah’s Witnesses could miss it is even more remarkable!
In Revelation, Jesus comes with the clouds and 1) all shall see him; and they also which “pierced” him, and 2) “and all kindreds of the earth shall “wail because of him.” So in both references, the Jews will all see him and in both they will mourn for him. There’s no way that Jehovah and Jesus could be two different entities. And when Jehovah comes, Zechariah notes that the grief shall be as if for “his only son,” and “shall be in bitterness for him, as…for his firstborn.” This prophecy’s references to an only son and a firstborn are distinctly messianic. The point is, when Jehovah returns and His feet stand upon the Mount of Olives, He will be the Son of God…his Firstborn.
Then shall the Lord go forth, and fight against those nations, as when he fought in the day of battle. And his feet shall stand in that day upon the mount of Olives, which is before Jerusalem on the east, and the mount of Olives shall cleave in the midst thereof toward the east and toward the west, and there shall be a very great valley; and half of the mountain shall remove toward the north, and half of it toward the south. And ye shall flee to the valley of the mountains…. (Zechariah 14:3-5)
In this prophecy, the “Lord” is clearly Jehovah, who will enter the fray on the side of the Jews. When the Jews see the wounds in his hands and feet, they will instantly realize who He is and that’s what will cause the grief and the lamentation amongst them. The entire Jewish nation will convert to Christianity in a day, but all the Earth will know that Jehovah and Jesus are one and the same.
Ummm...by the way, why do JW angels all have wings?
