What the Bible says about Sounding of the Seventh Trump
(From Forerunner Commentary)
This provides the time that this will take place—when God goes forth. This is the time of the end, and we may be able to pinpoint this to "the day of the Lord," the sounding of the seventh trump, the pouring out of the seven last plagues of God.
