Towards the end of the book of Revelation John hears somebody say: “Behold, I am coming soon, bringing my recompense with me, to repay each one for what he has done. I am the Alpha and the Omega, the first and the last, the beginning and the end” (Rev. 22:12–13). This is presumably Jesus speaking (cf. 22:16); and since God says nearly the same thing about himself in Revelation 21:6, it is inferred that John means to establish some sort of identity between Jesus and God. Richard Bauckham, for example, has said: “As a way of stating unambiguously that Jesus Christ belongs to the fullness of the eternal God, this surpasses anything in the NT” (R. Bauckham, The Theology of the Book of Revelation, 1993, 56-57).
