What Are The Seven Thunders & Who Will Reveal Them?

Will a group of men reveal the Seven Thunders, or were they already revealed through God's Provided one-man program?

Update: Should've added this quote as well.

147 When, the “thundered.” Remember, a loud clapping noise of a Thunder is a Voice of God. That’s what the Bible says, see, “a clap of Thunder.” They thought it was a thunder, but It was God. He understood It, for It was revealed to Him. See? It was a Thunder.
