“And he gave a great shout like the roar of a lion. And when he shouted, the seven thunders answered. When the seven thunders spoke, I was about to write. But I heard a voice from heaven saying, “Keep secret what the seven thunders said, and do not write it down.” Revelation 10:3-4
The angel “cried out with a loud voice, as when a lion roars.” His loud cry reflects the power and authority of God. The Old Testament prophets also connect a loud, lion like roaring voice with judgment. “Now prophesy all these things, and say to them, “The Lord will roar against his own land from his holy dwelling in heaven. He will shout like those who tread grapes; he will shout against everyone on earth.” (Jeremiah 25:30) “This is what he saw and heard: “The Lord’s voice will roar from Zion and thunder from Jerusalem! The lush pastures of the shepherds will dry up; the grass on Mount Carmel will wither and die.” (Amos 1:2)
The seven peals of thunder did not merely make a loud noise, but communicated information that John was about to write. In obedience to God’s commands, John had already written much of what he saw in his visions. Later in Revelation, John would once again be commanded to write what he saw in his visions. But before John could record the message of the seven peals of thunder, he heard a voice from heaven saying, “Seal up the things which the seven peals of thunder have spoken and do not write them.” Whether the voice was that of the Father, Jesus Christ, or an angel is not revealed. The command, however, clearly originated with God. The reason John was forbidden to record the message is not revealed. It may be that the judgment is simply too terrifying to be recorded. Any speculation as to the specific content of their message is pointless. If God had wanted it to be known, He would not have forbidden John to write it. They are the only words in the book of Revelation that are sealed. God will judge sin. Make no mistake if we don’t repent of our sins and start living for God, we will pay for our sin. The book of Revelation is a book of judgement, but it is also a book of victory. If we endure to the end, we will be victorious.
