“… and they will in the future reign forever and ever.” This speaks of our ETERNITY THEN. Rule begins in the Millennial Kingdom and will continue forever and ever in the new heaven and earth. It is a trustworthy statement, if we died with Him, we will also in the future live with Him; if we now endure, we will also in the future choose to reign with Him.
Faithful and true defines Yahweh and every word He has breathed. God who directs the spirit of the prophets sent His angel to show to His bondservants the things which now must soon choose to take place. Through revealing His thoughts, intentions, plans, desires, and action, Jesus wants His bride to fall ever more in love with him and be thoroughly convinced that He is worth waiting for, worth betting their lives upon.
