Indeed, it is clear Who is Coming back in Revelation chapter 1 and that is “the Alpha and Omega” which is the Same in Isaiah 44, and there it is clearly YHWH, and in Revelation 1 it is clearly Jesus Christ, therefore YHWH is the God of Israel, and therefore Jesus Christ is YHWH.
Behold, I am coming quickly, and My reward is with Me, to render to every man according to what he has done. "I am the Alpha and the Omega, the first and the last, the beginning and the end." Blessed are those who wash their robes, so that they may have the right to the tree of life, and may enter by the gates into the city.
FRiend, I've granted that is a valid interpretation, and have requested forbearance and respect for those Christians who interpret it differently.
