The tribulation will be a time of great trouble for the wicked, because of God’s judgments. It will also be a time of great persecution for the believers—or saints—because of the Antichrist’s persecution (Revelation 13:7). Daniel saw the Antichrist “waging war against the saints and defeating them” (Daniel 7:21). Of course, the saints’ eternal salvation is secure: Daniel also saw that “the Ancient of Days came and pronounced judgment in favor of the saints of the Most High, and the time came when they possessed the kingdom” (Daniel 7:22; cf. Revelation 14:12–13).
The tribulation saints will hear the gospel from several possible sources. The first is the Bible; there will be many copies of the Bible left in the world, and when God’s judgments begin to fall, many people will likely react by finding a Bible to see if prophecies are being fulfilled. Many of the tribulation saints will also have heard the gospel from the two witnesses (Revelation 11:1–13). The Bible says these two individuals “will prophesy for 1,260 days [three and a half years]” (verse 3) and perform great miracles (verse 6). And then there are the 144,000 Jewish missionaries who are redeemed and sealed by God during the tribulation (Revelation 7:1–8). Immediately following the description of their sealing in Revelation 7, we read of the multitudes of tribulation saints who are saved from every corner of the world (verses 9–17).
The tribulation saints will serve their Lord Jesus Christ in the midst of desperate surroundings. Faithful to the end, many of these believers will die for their faith. But in their death, they overcome; “They overcame [Satan] by the blood of the Lamb and by the word of their testimony; they did not love their lives so much as to shrink from death” (Revelation 12:11). And God will reward them: “He who sits on the throne will spread his tent over them. Never again will they hunger; never again will they thirst. The sun will not beat upon them, nor any scorching heat. For the Lamb at the center of the throne will be their shepherd; he will lead them to springs of living water. And God will wipe away every tear from their eyes” (Revelation 7:15–17).
We praise the Lord that the great day of trouble will also be a great day of grace. Even as God is meting out His just punishment on an unbelieving world, He will be restoring Israel to faith and extending grace to all who believe, both Jew and Gentile. God has always been in the business of saving people, and that salvation will still be available during the tribulation. Don’t wait until then, however; receive Jesus now (John 1:12).
