Revelation 1:4-8 (ESV Strong's)
4 John to the seven churches that are in Asia:
Grace to you and peace from him who is and who was and who is to come, and from the seven spirits who are before his throne, 5 and from Jesus Christ the faithful witness, the firstborn 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 forever and ever. Amen. 7 Behold, he is coming with the clouds, and every eye will see him, even those 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.”
In this passage we receive a greeting from the Three Persons of the one God, the Almighty who is the beginning and the end of man, and His Spirit who brings us this message. We’ve seen Him in the form of a man whose blood was spilled on our behalf, cleansing us from sin and making the Church a kingdom of priests. This is the kingdom of heaven which is manifest by His presence with and in us.
