Revelation 11:15 The seventh angel sounded his trumpet, and there were loud voices in heaven, which said:

“The kingdom of the world has become
the kingdom of our Lord and of his Messiah,
and he will reign for ever and ever.”

The seventh trumpet is the final judgement to come upon the earth. Christ sets up His kingdom, and rewards his faithful people. They receive a home in Heaven, a crown of life and live with Jesus forever. Satan and his angels and all who have chosen to reject the kingdom of Christ, and those who have persecuted the saints, will receive their final reward as well. God will “destroy” them in the lake of fire intended for Satan and his angels.

Then the seventh angel sounded: The seventh seal brought forth a profound silence (Revelation 8:1); the seventh trumpet initiates joy at the inevitable resolution. There can't be a more glorious proclamation than this: The kingdoms of this world have become the kingdoms of our Lord and of His Christ, and He shall reign forever and ever!

Have become the kingdoms of our Lord: In the ancient Greek grammar, the verb tense of have become indicates an absolute certainty about Jesus' coming and reign, even before the fact is accomplished.

How can there be such joy, when the King is not reigning completely yet? At the headquarters at a successful political campaign on election night, there is joy, even though it will be a while until their candidate is actually installed into office. The joy anticipates a certain result

Jesus is going to be King of the World again.
