Revelation was written to assure the recipients of the ultimate triumph of Christ over all who rise up against Him and His saints. Most will agree to this, The book was written in symbolism and because of that, many have over interpreted the book. People see more in the book than what it says.
It maybe because of these God warned us in Rev. 22:18-19 not to add or takeaway from the prophecy of this book. God knew that the symbols would be hard but give us a little help to our understanding of the book. Look at the verses I call the understanding keys to the book. Rev. 1:3 “Blessed is he who reads and those who hear the words of this prophecy, and keep those things which are written in it; for the time is near.” Rev. 22:6 “Then he said to me, “These words are faithful and true.” And The Lord God of the holy prophets sent His angel to show His servents the thing which must shortly take place.” Then we see the warning in Rev.22:10 And he said to me,“Do not seal the words of the prophecy of this book, for the time is at hand.”
Some of the symbolism we can understand because the answer is given in the book itself. Like the lamp stands are the churches 1:20.
I do not understand all the symbols of the book, for me it is like the strokes of a artist bush I may not understand or know what they are but I can know what the final picture is and enjoy the beauty, In the book of Revelation We can enjoy knowing that Jesus Christ and His saints are going to overcome. If I trust and obey I can and will be with Him in Heaven. How about You?
One point to keep in mind the Revelation will not teach us something that does not agree with the other books of the Testament of Christ
