What is to be finished when the seventh trumpet is about to sound?

Answer

"But in the days of the voice of the seventh angel, when he is about to sound, then is finished the mystery
of God, according to the good tidings which He declared to His servants the prophets." Rev. 10:7, R.V.
NOTE-The mystery of God is the gospel. Eph. 3: 3-6; Gal. 1: 11, 12. When this trumpet is about
to sound, therefore, the gospel will close, and the end will come. The "time of trouble," of Dan. 12: 1, and
the seven last plagues and the battle of Armageddon, spoken of in Revelation 16, will take place when this
trumpet begins to sound.
