Revelation 20:6 says, “Blessed and holy is he who has part in the first resurrection. Over such the second death has no power, but they shall be priests of God and of Christ, and shall reign with Him a thousand years.”

22:7 says, “Behold I am coming quickly! Blessed is he who keeps the words of the prophecy of this book.”

22:14 says, “Blessed are those who do His commandments, that they may have the right to the tree of life, and may enter through the gates into the city.”

The Greek word for revelation means an unveiling or disclosing of a reality that previously has not been perceived. Revelation 1:1 says, “The Revelation of Jesus Christ, which God gave Him to show His servants—things which must shortly take place…” 

The word ‘shortly’ has a different meaning than what we might mean today. The use in this book is that they can take place at any time ~suddenly.
