(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.
There are certain crucial statements in the book of Revelation that really nail down the whole purpose of these visions and Revelation 10:7 is one of those key statements. An interpretation of the book that does not harmonize with the key statements will need to be discarded, and a fresh look of the book through the eyes of key statements is necessary. I am speaking by experience. When I once thought I understood the book, my understanding did not stand up to scriptures like this one. I once had ideas that Revelation dealt with the fall of the Roman Empire (5th century), the final Day of Judgment and Heaven. I should have been more careful and respected God’s word. When God said that this book contains the events that would take place shortly (1:1, 22:6), I should have trusted in that fact. Revelation is not the final package that wraps up the whole world and its history (as many still believe), it is about the events which would finish the mystery of God (10:7). Verse 7 explains that what he had shown to his prophets would be completed. Here there are two important things to understand: (1) the mystery of God, and (2) what God had declared to the prophets. Both of those are interchangeable. The mystery of God is salvation through Christ which had been revealed in the first century (Colossians 1:26-28). Prior to that time even the prophets counted it a mystery (1 Peter 10-11). But it was those prophets that still declared to God’s people in the Old Testament the coming salvation. The word “declared” used here in 10:7 is the Greek word “euaggelizo,” which translates into the English word “evangelism.” The prophets preached the good news (or gospel) to those under the old covenant. And we can certainly see those things in the books of the prophets today. However, there is more to the preaching of the prophets and, therefore, the mystery of God. A quick look through Isaiah, Ezekiel, Joel, Daniel, and others, will reveal that the prophets warned the Jewish people of their coming destruction. At the writing of Revelation, such a destruction had yet to be fulfilled, but, according to 1:1 and 22:6, it would occur very soon.
In Luke 21, Jesus said: (20) “And when ye shall see Jerusalem compassed with armies, then know that the desolation thereof is nigh. (21) Then let them which are in Judaea flee to the mountains; and let them which are in the midst of it depart out; and let not them that are in the countries enter thereinto. (22) For these be the days of vengeance, that all things which are written may be fulfilled.”
As Jesus, like Daniel and others, spoke of the destruction of Jerusalem, he noted “these be the days of vengeance, that all things which are written may be fulfilled.” God taking vengeance on his unfaithful people was the final theme of the prophets, after which, all things that had been written in the Old Testament would be completely fulfilled. This verse (Revelation 10:7), speaks in perfect unison to the statements of Jesus. Other places in Revelation also refer to this: 6:10, 11:18, 16:6, 18:20, 18:24, and 19:2. This is a book about God’s vengeance on his unfaithful people who had rejected their Messiah, and God’s avenging of his faithful who they had slain in the process (Luke 13:33-35, Luke 11:50-51, Acts 13:27). How does the fall of the Roman Empire relate to that? It doesn’t; not in reference to the timeframe nor the theme of the book. This book was to bring comfort to the Lord’s faithful in the first century that Christ will help them and reward them, they need not fear. Christ will conquer.
