Revelation 1:8 “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.”
Verses 5 through 7 have John focusing his readership on Jesus Christ. From being the faithful witness, to the tribes of earth mourning because of Him at His triumphant return. Skipping ahead briefly to verse 9, we also find John speaking about the kingdom of Christ and his subsequent exile because of his witness regarding Jesus.
