Revelation 1:1 The Revelation of Jesus Christ, which God gave unto him, to shew unto his servants things which must shortly come to pass; and he sent and signified it by his angel unto his servant John:

This book is the unveiling of future events leading to the Second Coming of Christ ushering in the transition from time to eternity, here, spoken of, as the Revelation of Jesus Christ. Jesus, is He Whom the Godhead has appointed to reveal the truth concerning the future of mankind. The message is given from God through Jesus Christ, conveyed by His angel unto John, the Apostle of Christ, to His servants.

Who are His servants? The receipients of the letter who hear the words of this prophecy, and keep those things which are written therein (v3). The Lord pronounced them “blessed”. These events must shortly come to pass.
