I certainly wouldn't treat Jesus' testimony as "drivel".
In order to have a legitimate Kingdom there must be the right to rule, which Jesus has; there must be a domain... ie, subjects, which Jesus has; and there must be an exercise of that rule, which Jesus is not doing.
Hmmm...Guess what - Jesus is ruling right now, and even better, Christians are ruling with him! That's what the Bible has to say - I leave it up to your great knowledge of the Scriptures, for surely you must have found some verses that tell you Jesus in not in charge of his subjects?
If Jesus Christ reigned right now, His followers would actually follow Him and His enemies would not only fear Him, but would bow down and acknowledge Him as Lord, to the glory of God, The Father.
Jesus is now reigning and His followers really follow Him! They take up the cross and follow Jesus because He is the "head", i.e., the ruler of His "called out assembly" of saints. As for His enemies, when He comes again, they will be destroyed along with this world, just as II Pet. 3:1-18 tells us. Paul said similar things in II Thess. 1:3-10 and 2:1-12
Utter nonsense. I have taught 1st graders in Sunday School who would laugh at this silly statement and then refute it with a simple question, "if we are ruling with Him, why don't the bad people do what we say?" We WILL rule with Him, to be sure. But what we are doing right now isn't "ruling."
Clean up your theology... it is leaving a mess all over the place.
