S – “…but in the days when the seventh angel will blow his trumpet, then the mystery of God will be completed, as he announced to his servants the prophets.”

Revelations 10:7 CSB

O – Commentary:

Announcement was made that the seventh … trumpet would bring about the accomplishment of the mystery of God. This mystery had been previously announced to God’s prophets. The reference, therefore, is not to hidden truth but to the fulfillment of many Old Testament passages which refer to the glorious return of the Son of God and the establishment of His kingdom of righteousness and peace on the earth. While God’s purposes are not necessarily revealed in current events where Satan is allowed power and manifestation, the time will come when Satan no longer will be in power and the predictions of the Old Testament prophets will be fulfilled. Then all will know the Lord and the truth about Him (Jer. 31:34). Here again is evidence that the seventh trumpet introduces the seven bowl judgments of God’s wrath described in Revelation 16.

 “Revelation,” in The Bible Knowledge Commentary: An Exposition of the Scriptures

A –  The connection between the Old Testament and the New Testament is amazing.  God revealed the mystery of the Messiah and the Kingdom of Heaven being established.  All of it points to God being known in fullness and in truth.

R – Heavenly Father, we stand in awe of you – you are the one, true God.  Continue to reveal your mysteries to us.  We want to know you in fullness and truth.  We want to draw closer to who you are so we can reflect that to others in our relationships with them.
