The revelation of Jesus Christ that God gave Him to show His slaves what must quickly take place. He sent it and signified it through His angel to His slave John,

John:

To the seven churches in Asia.

Grace and peace to you from the One who is, who was, and who is coming; from the seven spirits before His throne;

I, John, your brother and partner in the tribulation, kingdom, and endurance that are in Jesus, was on the island called Patmos because of God’s word and the testimony about Jesus.

I, John, am the one who heard and saw these things. When I heard and saw them, I fell down to worship at the feet of the angel who had shown them to me.
