The revelation began with the Father and then proceeded from the Father to the Son then from the Son through an angel to His bond-servant John and finally, from John to the the seven churches that were in Asia Minor which is now Turkey. The revelation of Jesus Christ means the revelation (unveiling) is by or from Christ.
How did John receive the revelation? John was probably incarcerated on the island called Patmos because of his testimony of Jesus. He was in the Spirit on the Lord’s day when he heard a loud voice behind him, saying, “Write in a book what you see, and send it to the seven churches" (1:9-11).
The churches were listed as a circular postal circuit that a person delivering a letter might travel starting from the coastal city of Ephesus, then to Smyrna and Pergamum to the north, then in a southeastern direction to Thyatira, Sardis, Philadelphia and finally Laodicea (1:11).
When John turned around, he saw a vision of someone like a son of man (1:13) ... Jesus Christ, the Living One who was once dead but now alive for ever and ever (1:18). He had seven stars in his right hand and was walking among seven golden lampstand (1:16,12-13).
John was so overwhelmed with fear by what he saw, he fell down at Christ's feet like a dead man. Jesus placed His right hand on John and presented Himself as the resurrected One (once dead but now alive) and the One with authority over the state of death and Hades, the place of the dead (1:17-18).
Jesus is coming with the clouds ... (1) every eye will see Him and (2) all the peoples of the earth will mourn because of him (1:7). He was crucified and died for you and me. What will be your feelings at His coming? Are you ready to meet him? If not, how can you prepare for His coming?
