A big takeaway from our teaching time this morning in Revelation 10 is the seven thunders, which John was told not to write down for us to know what they were. As followers of Christ Jesus, we don’t always have all the information we may think we need or want, but Deuteronomy 29:29 reminds us “The secret things belong to the Lord our God, but the things that are revealed belong to us and to our children forever, that we may do all the words of this law” (ESV).

Also, here are the notes that I said I would share, from David Guzik’s Commentary on Revelation, regarding the “mystery of God”…

“The mystery of God would be finished: What mystery? One important aspect of this mystery is that it has been declared to His servants the prophets.

In Biblical vocabulary, a mystery isn’t something no one knows. A mystery is something no one could know unless it was revealed to him. If you could know it by intuition or personal investigation, it isn’t a mystery, because mysteries must be revealed. Therefore, something can be known and still be a mystery in the Biblical sense.

The mystery of God: It’s hard to say what this precise mystery of God is, because the phrase – or its equivalent – is used for a many different aspects of God’s plan.

• The ultimate conversion of the Jewish people is called a mystery  (Romans 11:25)
• God’s purpose for the church is called a mystery (Ephesians 3:3-11)
• The bringing in of the fullness of the Gentiles is called a mystery (Romans 11:25)
• The living presence of Jesus in the believer is called the mystery of God (Colossians 1:27-2:3)
• The gospel itself is called the mystery of Christ (Colossians 4:3)

The mystery of God: In this context, the mystery of God probably refers to the unfolding of His resolution of all things, the finishing of His plan of the ages.

“The mystery of God which is declared as subject to fulfillment is unfolded therefore in the Old Testament in the many passages which speak of the establishment of the kingdom of God on earth.” (Walvoord)

Possibly, the mystery also regards the great question “Why does God allow Satan and man to rebel and go their own way?” The idea may be that this question, this unanswered mystery, is coming to an end under rule of Jesus. God is beginning the end, the resolution of all things, the gathering together (resolution, summing up) of all things in one in Jesus (Ephesians 1:10).”
