The correct answer is "Thessalonians." In Paul's letter to the Thessalonians, he wrote about the end of the world and the coming of Jesus Christ to gather his followers. Paul explained that everyone, both the living and the dead, will share in Christ's Resurrection at the time of his Second Coming. This means that those who have already died and those who are still alive will all come back to life and be with Jesus forever. This event is a central belief in Christianity and is seen as a time of judgment and reward for people's actions during their lives.
