The first Epistle to the Thessalonians is a letter of simplicity, gentleness and affection. It was written by Paul from Corinth shortly after his departure from Thessalonica in early A.D 51 (Acts 18:5; 1 Thessalonians 3:6). It was probably among the earliest of Paul’s inspired writings. Thessalonica was a Roman free city and the capital of the province of Macedonia. It was a port city and was on the main east-west Roman highway. Today this city is known by the name, Salonika. Paul visited Thessalonica on his second missionary journey and preached the gospel in the synagogue for three successive Sabbaths (Acts 17:1-9). It was during his visit that the light of the gospel reached this pagan city. Paul used every opportunity to reach people with the gospel of Christ. Thus the church was established. When Paul proved that Jesus of Nazareth is the promised Messiah, the unbelieving Jews incited a riot in the city. Because of the violent persecution, Paul was sent away to Berea for his personal safety. Paul wanted to visit them again but Satan hindered him (1 Thessalonians 2:17-18). When Paul was in Athens, he sent Timothy to help this rapidly growing church (1 Thessalonians 3:1-6). It is evidently in response to Timothy’s reports that Paul wrote this letter. The purpose of writing this letter was to commend the church for their steadfast faith and love in the Lord (3:6). They became an example to all believers in Macedonia and Achaia (1 Thessalonians 1:7). In addition, Paul wanted to admonish them of the importance of personal holiness. He also warns the church of the danger of immoral practices of the heathens (1 Thessalonians 4:1-8). Also Paul wanted to instruct them concerning the Lord’s return and correct them about the erroneous ideas concerning the resurrection of the dead and the coming of Christ (1 Thessalonians 4:13-18). This epistle is a source of great comfort to all believers.
