"The nature of the 7th trumpet

 shows that "time is no more, and that the mystery of God is finished, 

Rev. 10:6-7

"And sware by him that liveth for ever and ever, who created heaven, and the things that therein are, and the earth, and the things that therein are, and the sea, and the things which are therein, that there should be time no longer:

But in the days of the voice of the seventh angel, when he shall begin to sound, the mystery of God should be finished, as he hath declared to his servants the prophets."

At the 7th trumpet, Jesus rules and reigns forevermore, He has taken His great power and reigned,and He rewards the righteous, and judges the wicked. Both Jesus and Paul declare that when Jesus comes, His reward is with Him, and He rewards everyone according to their works, 

Revelation 22:12 

"And, behold, I come quickly; and my reward is with me, to give every man according as his work shall be.

1 Timothy 4 

4 The Spirit clearly says that in later times some will abandon the faith and follow deceiving spirits and things taught by demons."
