Alpha is the first letter of the Greek alphabet and Omega is the last letter. In Revelation 1:8 Jesus says; "I am the Alpha and the Omega, the Beginning and the End, says the Lord, who is and who was and who is to come, the Almighty." Jesus is here declaring himself to be everything from A to Z and in complete control of history. When he returns for his Second Coming, he will do so with all power and majesty in contrast to his first coming as a humble servant. All the Christian world awaits and joins the voice of the apostle John in Revelation 22:20; "Amen. Even so, come, Lord Jesus!"
