We also read:
"And there shall be no more curse: but the throne of God and of the Lamb shall be in it; and his servants shall serve him: And they shall see his face; and his name shall be in their foreheads" (Rev.22:3-4).
There is only ONE on the throne of God and of the Lamb---
"they shall see His face."
And the One on the throne of God and of the Lamb says that He is God and He also says that He is
"Alpha and Omega" and the
"beginning and the end":
"And he that sat upon the throne said, Behold, I make all things new. And he said unto me, Write: for these words are true and faithful. And he said unto me, It is done. I am Alpha and Omega, the beginning and the end. I will give unto him that is athirst of the fountain of the water of life freely. He that overcometh shall inherit all things; and I will be his God, and he shall be my son" (Rev.21:5-7).
Since there can only be One Alpha and Omega and only One Who is the beginning and the end that means that the Lord Jesus is the God:
"And, behold, I come quickly; and my reward is with me, to give every man according as his work shall be. I am Alpha and Omega, the beginning and the end, the first and the last" (Rev.22:12-13).
It is the Lord Jesus who is said to be coming quickly:
"He which testifieth these things saith, Surely I come quickly. Amen. Even so, come, Lord Jesus" (Rev.22:12-13).
Therefore, we can know that the Lord Jesus is Jehovah, the Only One who can be described as being the
"Alpha and Omega, the beginning and the end."
The reference to the "Father" in this verse is not speaking of the First Person of the Godhead but instead Jehovah the Father:
"But now, O LORD, thou art our father; we are the clay, and thou our potter; and we all are the work of thy hand" (Isa.64:8).
The Lord Jesus cannot be excluded from being the Potter since
"by Him were all things created" (Col.1:16).
Therefore, the Lord Jesus is the LORD, Jehovah.
