One-fourth of the earth will be affected by the grim reapers - the four horsemen of the Apocalypse (Revelation 6:1-8).  This lesson on 6:9-17 is broken into two halves: I. True Refuge in the Rock (verses 9 to 11) and II. False Refuge in the Rocks (verses 12-17).  The true refuge is about slain Tribulation saints in Heaven and their response to the first four seal judgments: prayer.  The false refuge is by the ungodly on earth and their response to the first four seal judgments: fear.
