Who is the Alpha and Omega in Revelation 21:6?
The Alpha and Omega in Revelation 21:6 is Christ, the Lord Jesus. The passage states that only one person of the Godhead says this, and He is identified as Christ, who refers to Himself as the beginning and the end.
Les explains that Revelation 21:6 records the words, "It is done. I am Alpha and Omega." He notes there is only one person of the Godhead who says that, and identifies Him as Christ. Les then states that the Lord Jesus here again refers to Himself as the beginning and the end. This follows the surrounding description of God dwelling with men, wiping away all tears, ending death, sorrow, crying, and pain, and making all things new.
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.
