Paul wrote this letter to the believers in the city of Thessalonica. He wrote it after the Jews in the city forced him to leave. In this letter he said he considered his visit to them a success, even though he was forced to leave.
Paul also responded to the news that Timothy told him about the Thessalonian believers. He encouraged the believers to live in a way that honors God. He wanted them to be ready for Jesus Christ when he comes again.

## Part 2: Important Religious and Cultural Concepts ##
Paul wrote a lot in this letter about Jesus' eventual return to Earth. When Jesus returns, he will judge all mankind. He will also rule over creation as king. And he will cause there to be peace everywhere.
Paul made clear that those who die before Christ's return will come back to life and be with Jesus. They will not remain dead forever. Paul wrote this to encourage those who worried that those who died would miss the great day when Jesus returns.
Paul meant to express the idea of very a close union with Christ and the believers. Please see the introduction to the Book of Romans for more details about this kind of expression.
