When we compare the descriptions of Himself Jesus gives John to write in the letters to the seven churches (ekklesias), with the observations and mentions John makes of his initial experience in the Spirit with the ascended Christ, we notice how readily they match, along with some other passages for the sixth and seventh letters.
Rev 2:1
(1) Unto the angel of the church of Ephesus write; These things says He that holds the seven stars in his right hand, who walks in the midst of the seven golden candlesticks;
Rev 2:8
(8) And unto the angel of the church in Smyrna write; These things says the first and the last, which was dead, and is alive;
Rev 2:12
(12) "And to the angel of the church in Pergamos write, 'These things says He who has the sharp two-edged sword:
Rev 2:18
(18) "And to the angel of the church in Thyatira write, 'These things says the Son of God, who has eyes like a flame of fire, and His feet like fine brass:
Rev 3:1
(1) "And to the angel of the church in Sardis write, 'These things says He who has the seven Spirits of God and the seven stars: "
Rev 3:7
(7) "And to the angel of the church in Philadelphia write, 'These things says He who is holy, He who is true, he that has the key of David, he that opens, and no man shuts; and shuts, and no man opens;
Rev 3:14
(14) And unto the angel of the church of the Laodiceans write; These things says the Amen, the faithful and true witness, the beginning of the creation of God;
I hope you have enjoyed these matching passages as much as I have, especially in contemplating the differences between Christ as John observed and experienced Him whilst He was on earth, and as we read of Him after He ascended.
