Hi this question has been asked and answered by me in a post dated 7/8/21 titled: Pastor Jimmy Evans says that the Temple Institute already has things in order to rebuild in Jerusalem and soon there will be a rapture of the church. How soon do you see us being raptured?
In adding information about a trumpet blast there are several and I feel the one you are referring to actual announces something:
Revelation 11:15
Easy-to-Read Version
The Seventh Trumpet Blast
15 The seventh angel blew his trumpet. Then there were loud voices in heaven. The voices said,
“The kingdom (Government) of the world has now become the kingdom (Government) of our Lord and of his Messiah.
And he will rule forever and ever.”
