After a short ministry in Thessalonica, Paul was forced to leave (Acts 17:1-10). Probably less than a year later, Paul heard that the believers there were being persecuted. Paul wrote to reassure them that their faith and sufferings were not in vain. This is one of his earliest letters.
Salutation (verse 1)
Verse 1 presents the authors and the audience: “Paul, Silas and Timothy, to the church of the Thessalonians in God the Father and the Lord Jesus Christ: Grace and peace to you.”
