All prophecy has not yet been fulfilled!

Revelation 11:15 says, "Then the seventh angel sounded; and there were loud voices in heaven, saying, "The kingdom of the world has become the kingdom of our Lord and of His Christ; and He will reign forever and ever."
This passage speaks of what is still to come.  The seventh trumpet includes the 7 bowl, final judgments depicted in Rev. 16 and all the events leading up to the establishing of the millennial kingdom in Rev. 20.

1 Corinthians 15:52 says, "In a moment, in the twinkling of an eye, at the last trumpet; for the trumpet will sound, and the dead will be raised imperishable, and we will be changed."
This passage also speaks of what is still to come, the rapture of the church.  When the trumpet sounds all believers will be raptured.  1 Thess. 4:16-17 describes the rapture of the church even further.

1 Thessalonians 4:16-17 says, "For the Lord Himself will descend from heaven with a shout, with the voice ofthe archangel and with the trumpet of God, and the dead in Christ will rise first. 17 Then we who are alive and remain will be caught up together with them in the clouds to meet the Lord in the air, and so we shall always be with the Lord."
