Revelation 10:7

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.

In the days of the voice of the seventh angel ... These words appear to mean merely "when the seventh angel sounds." It is a stylized or idiomatic way of saying it. Certainly we reject the notion of Wordsworth to the effect that "This verse points to a brief respite, during which men may yet repent."[33]

Then is finished the mystery of God ... Lenski correctly described this mystery as:

God's scheme of redemption. The eschatological mystery of the world's history. The glorious completion of the divine kingdom. The glorious consummation of God's kingdom.[34]

The theology of mystery has been extensively discussed by this writer in his book entitled The Mystery of Redemption.

There is that about the gospel which is not accessible to the mind of men. (There is still a mystery, and it is not even finished yet.) Left to ourselves, we would never have worked out that God would save men as he does. It had to be revealed.[35]

According to the good tidings declared ... These words make certain the identification of the mystery here as the gospel of our Lord Jesus Christ, both the facts of its being called the "good tidings," and its being "declared" unto the prophets are proof of it. "The very word here rendered declared means preached the gospel."[36]

Prophets ... These are those men of both the Old Testament and the New Testament "through whom God spoke to his people."[37]
