The revelation of Jesus Christ, which God gave Him to show to His bond-servants, the things which must soon take place; and He sent and communicated it by His angel to His bond-servant John....This revelation [apokalupsis] is "about" Jesus rather than "from" Jesus. The genitive in the Greek hints at this. Also, I think it should be noted that John uses both His earthly name and His title name. This likely encapsulates His humanity and divinity and who He is and what He's done.
John uses "bond-servants" [doulos] or "slaves" to remind those in the seven churches that the way they live in the last days should be as contrite servants and not prideful heirs, especially in the midst of persecution [1.9].
"Must" [dei] is small, but significant. It is a reminder of God's absolute control over future events before the return of His Son.
The words "to show" [deiknumi] and "communicated" [semaino] are both words that imply more than mere description. They suggest demonstration, indication, and the use of pictures and/or symbols [even in 1.20 John begins to explain some of his imagery]. No one should take this and interpret Revelation to mean whatever was on CNN last night, but should seek to understand why OT prophets/writers used the symbols they did and further, why John picks up on them here in the Apocalypse.
