Revelation 1:4, 8

John, to the seven churches that are in [the province of] Asia: Grace [be granted] to you and peace [inner calm and spiritual well-being], from Him Who is [existing forever] and Who was [continually existing in the past] and Who is to come, and from the seven Spirits that are before His throne, [Is 11:2]

“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]
