The Thessalonian church was suffering, grieving, and confused about the Day of the Lord. They feared that believers who died would miss Christ's return and that judgment might fall on them when Jesus came. Paul writes 1 Thessalonians 4-5 to rebuild their hope by giving them a true understanding of Christ's return. He teaches that Jesus will return once, pubicly and victoriously, raising the dead in Christ, reuniting body and sol, and gathering all believers together. The Day of the Lord is not a threat to God's people because they are children of the light, destined not for wrath but for salvation. Therefore, Christians must live awake and sober, rembmering their identity, encouraging and building one another up, and caring for the weak and fainthearted. The final destination of Christian hope is life with Jesus forever, where every tear is wiped away and all suffering ends. The return of Jesus gives believers unshakable hope for today and until the day He returns.
