this is about Jesus earthly Ministry and has nothing to do with His eternal Kingdom.
Revelation 11:15 is very clear about Jesus Kingdom and Rule:
"The kingdoms of the world have become our Lord's and his Christ’s and He shall Reign for ever and ever."
The Greek is very important here, the Greek verb, βασιλευσει, is in the singular number, which can either mean, Jesus shall Reign for ever and ever"; or, "Our Lord", which is "The Father", Reigns jointly with Jesus Christ. In any case, Jesus' Kingdom and Reign is Eternal, and co-equal with the Father!
