"'I am the Alpha and the Omega,' says the Lord God, 'who was, and is, and is to come, the Almighty.'" (Rev. 1:8)
Later in Revelation (see Chapter 22, starting vs. 12) he repeats the phrase and adds (vs. 16) "I, Jesus, have sent my angel..."
It can't be any clearer as to the true identity of Jesus. Those religious groups that claim he was just a man, not God, have not read these verses. It's astonishing that the God of the universe would have come to earth and paid the price Himself for our sin, so that we might live with Him throughout eternity. None of us deserve it, but praise God He was willing to do it!
