The tribulation draws primarily from Daniel's prophecy of seventy weeks (Daniel 9:24-27), where the final 'week' of seven years represents a period of unprecedented distress. Jesus referenced this in His Olivet Discourse (Matthew 24), warning that the tribulation would surpass any suffering the world has known. Revelation chapters 6 through 18 describe the unfolding judgments in three sequences: seven seals, seven trumpets, and seven bowls of wrath. Christians disagree on the relationship between the church and the tribulation. Premillennialists generally expect a literal future tribulation, while amillennialists often see these prophecies as describing ongoing persecution throughout church history. The pre-tribulation view holds that believers will be raptured before this period begins, while post-tribulationists believe the church endures it under God's protection. Regardless of one's view on timing, the tribulation passages emphasize God's sovereignty over history, the ultimate defeat of evil, and the call to faithfulness even amid suffering.
