The sermon unfolds the seven seal judgments of Revelation, focusing on the fifth and sixth seals to reveal the escalating divine judgment during the tribulation period. It emphasizes the martyrdom of believers whose souls are seen under the altar, their cry for justice, and God's direction for them to rest until the full number of martyrs is completed, underscoring the cost of faith in a hostile world. The sixth seal then depicts cosmic upheaval—earthquakes, darkened celestial bodies, and the heavens rolling up—culminating in universal terror among the unrepentant, who acknowledge God's wrath yet refuse to turn from their sin. Drawing from prophetic texts in Isaiah, Jeremiah, Amos, and Zephaniah, the preacher underscores that this day of the LORD is a time of judgment, where pride is humbled and mankind is filled with fear. He underscores that the only hope to escape that time is to be cleansed by the Lamb's blood now. This shows the urgent need for evangelism today to help many be ready for Christ's return.
