Rev 1:8

8 “I am the Alpha and the Omega, the Beginning and the End,” says the Lord God, “who is and who was and who is to come, the Almighty.” 

I am the Alpha and the Omega – have we really heard God’s voice here (John 5:37)? The Spirit of Christ, as the Word, is speaking for the invisible God, as He did in the Old Testament. Zechariah prophesied, “In that Day, it shall be the LORD one (ECHAD) and His name one.” Christ and God again form “one unit” as they did in the Old Testament, ie Yihvah our ELOHIM (I), Yihvah (and the Father), ECHAD (are one).

The meaning of “Alpha and the Omega” and “the First and the Last” is that God was “the LORD” before Christ became “the Lord,” and God is now “the LORD” again. Paul said “when all things are submitted to Christ then Christ will submit to God.” (1 Cor 15:28)

Says the Lord God – this is the first time that God has been called the Lord, since Christ’s resurrection, except when calling God “the Lord of creation.” In the Book of Revelation, God is the only Lord after the Lord’s Day.

the Almighty – in Exod 6:3, Yihvah ELOHIM (Christ as the ELOHIM) told the people of Israel, “I appeared to Abraham, and Isaac, and Jacob as “God Almighty” but by my name Yihvah (He WILL BE) I was not known to them.” “El Shaddai” meaning “God Almighty” appeared 6 times in the Old Testament, and will appear 6 times in the Book of Revelation.
