In Revelation 10:7 what is the “mystery of God” that was finished by the 7th trumpet?

Question

Rev 10:7 KJV - 7 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.

Is the singular "mystery of God" referring to the OT (IE: Psalm 25:14) or the gospels ("gospel of the kingdom")? Or to Paul's "new creation"? Or are they all the same mystery?

Also, what does it mean that the mystery of God is "finished"?

Note:

A look at the Greek of the passage:

Answer 1

Revelation 10:5-7 (DRB) And the angel, whom I saw standing upon the sea and upon the earth, lifted up his hand to heaven, 6 And he swore by him that liveth for ever and ever, who created heaven, and the things which are therein; and the earth, and the things which are in it; and the sea, and the things which are therein: That time shall be no longer. 7 But in the days of the voice of the seventh angel, when he shall begin to sound the trumpet, the mystery of God shall be finished, as he hath declared by his servants the prophets.

What is spoken of as being heralded by the seventh trumpet appears to refer to the universal or general judgement, and the consummation of all things.

A few lines later we read what apparently confirms such:

Revelation 11:15-18: (DRB) And the seventh angel sounded the trumpet: and there were great voices in heaven, saying: The kingdom of this world is become our Lord's and his Christ's, and he shall reign for ever and ever. Amen. 16 And the four and twenty ancients, who sit on their seats in the sight of God, fell on their faces and adored God, saying: 17 We give thee thanks, O Lord God Almighty, who art, and who wast, and who art to come: because thou hast taken to thee thy great power, and thou hast reigned. 18 And the nations were angry, and thy wrath is come, and the time of the dead, that they should be judged, and that thou shouldest render reward to thy servants the prophets and the saints, and to them that fear thy name, little and great, and shouldest destroy them who have corrupted the earth.

It must refer to the Redemption in general as looked at as the whole story of human history, and as complete—"finished"—at its end.

Answer 2

Colossians makes reference to this:

Colossians 1:24-27

I now rejoice in my sufferings for you, and fill up in my flesh what is lacking in the afflictions of Christ, for the sake of His body, which is the church, of which I became a minister according to the stewardship from God which was given to me for you, to fulfill the word of God, the mystery which has been hidden from ages and from generations, but now has been revealed to His saints. To them God willed to make known what are the riches of the glory of this mystery among the Gentiles: which is Christ in you, the hope of glory.

There is a competing mystery referenced in scripture also, which is called the mystery of iniquity, or the mystery of lawlessness, which is in reference to the "sinful kingdom" of the Antichrist power. (See 2 Thessalonians 2:7 and Revelation 17:5)

The Bible presents us with two competing spiritual kingdoms or paths.

Romans 6:16

Do you not know that to whom you present yourselves slaves to obey, you are that one’s slaves whom you obey, whether of sin leading to death, or of obedience leading to righteousness?

Both of these are also likewise represented as leaven which pervades the being and influences the entire person.

Thus, the mystery of lawlessness is the principle of sin in the heart, and the mystery of God is the antithesis to this: namely, the leaven of the Spirit which produces righteousness in the heart.

And so, when the seventh trumpet sounds, the leaven is finished working, and it's time to take the bread out of the oven. The spreading and multiplying of righteousness has finished, and there is nothing more to be done.
