“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.”
Here Jesus identifies as the Alpha and the Omega, the beginning and the ending, which was and is and is to come.
Jesus Christ is the eternal God, with no beginning and no end, the end all be all of all and, as such, is the Almighty, Sovereign Lord. Jesus here makes a clear claim to Deity. He says, “I am. I am God.” And he does so four times in the book of Revelation.
“Saying, I am Alpha and Omega, the first and the last: and, What thou seest, write in a book, and send it unto the seven churches which are in Asia; unto Ephesus, and unto Smyrna, and unto Pergamos, and unto Thyatira, and unto Sardis, and unto Philadelphia, and unto Laodicea.” Revelation 1:11
“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.” Revelation 21:6
“I am Alpha and Omega, the beginning and the end, the first and the last.” Revelation 22:13
The Critical Text has a bastardized verse 11, in that it is missing Christ’s divine self-ascription. That said, the point stands. Jesus is the one and only God. He is eternal. Though he became a man, he has no beginning, for he has ever been God. Neither Muslims nor Jehovah’s Witnesses want to admit that Christ claims divinity. Revelation stands as a firm monument against their heresy. Mormons teach that there is more than one God. But Revelation stands as a firm monument against their heresy as well. God is the Alpha and the Omega. The Alpha and Omega is Christ. Christ is God; and, besides him, there is no God. “Thus saith the Lord the King of Israel, and his redeemer the Lord of hosts; I am the first, and I am the last; and beside me there is no God” (Is 44:6).
In awe before the eternal, almighty Christ, let all mortal flesh keep silence. And when you open your mouth, make sure it is to extol the greatness of the King.
