Revelation 1: 5 - 8
5 and from Jesus Christ the faithful witness, the first-born of the dead, and the ruler of kings on earth. To him who loves us and has freed us from our sins by his blood
6 and made us a kingdom, priests to his God and Father, to him be glory and dominion for ever and ever. Amen.
7 Behold, he is coming with the clouds, and every eye will see him, every one who pierced him; and all tribes of the earth will wail on account of him. Even so. Amen.
8 "I am the Alpha and the Omega," says the Lord God, who is and who was and who is to come, the Almighty.
