A question like that always throws me for a loop because the bulk of Scripture answers your question.
He's the King now, He rules forever and His Kingdom will never end, He's seated on the throne now in fulfillment of prophecy, He's also seated upon the throne of our hearts, He said His Kingdom is now, told Pilate that He is the King, received the Kingdom in its fullness upon resurrection, gave us the keys to the Kingdom (how could He do that, if they weren't His to give?), gave us the Kingdom, rebuilt the tabernacle of David so that all of mankind can seek the Lord, He's King of King and Lord of Lords ... and yes, we rule and reign with Him ... we are kings and priests unto God ... NOW.
I might add one verse of interest (I can provide scripture for everything above, but you should recognize each one by the text between the commas if you know the Word, which I know you and Bookie especially do) ... most dispensationalists would agree that Revelation 2-3 were written to "the churches" we live in today and they super-spiritualize those verses so that THEIR church could be the lukewarm church, etc. So Revelation 3:21 says "to him who overcomes, I will grant to him to sit down with Me on My throne, as I also overcame and sat down with My Father on His throne" ... He's already seated on the throne. He's not up there playing tiddleywinks.
Also consider that Zechariah 6:12-13 says that Jesus will build the temple of the Lord (that would be us, now) and He will bear the honour and sit and RULE on His throne...
"But of the Son He says, Your throne, O God, is forever and ever, and the righteous scepter is the scepter of His Kingdom" (Heb 1:8) (tons of OT prophecy to back that up)...
Why is the world in such a disastrous mess, then? Because most of the church has been taught that we're not supposed to be doing the ruling-and-reigning thing ...
He must reign (NOW) until He has put all enemies under His feet. Who must reign? Jesus. Who puts them under His feet? Jesus. Who does He use to do that with? Us. The Kingdom is at hand. We are kings and priests unto God with the authority to rule and reign with Him, right here, right now, making earth be as Heaven within our sphere of influence. Now.
That's not hyper-spiritual ... it's co-labouring.
