Revelation 1:8, 11

“I am the Alpha and the Omega [the Beginning and the End],” says the Lord God, “Who is [existing forever] and Who was [continually existing in the past] and Who is to come, the Almighty [the Omnipotent, the Ruler of all].” [Is 9:6]

saying, “Write on a scroll what you see [in this revelation], and send it to the seven churches—to Ephesus and to Smyrna and to Pergamum and to Thyatira and to Sardis and to Philadelphia and to Laodicea.”
