Paul wrote two letters to the church at Thessalonica, a major port city of Macedonia in the 1st century AD. These letters were probably sent by Paul in AD 50 or AD 51, while he was staying in the city of Corinth during his second missionary journey (Acts 16-18). This was during the reign of the Roman emperor Claudius. In these two letters Paul is generally upbeat. In the first he notes the good report about the church that he had received from Timothy, and he also speaks of the coming of the Day of the Lord, a theme to which he returns in the second letter. The theme chosen for this study, “Excel Still More,” comes from 1 Thess 4:1, and seems to encapsulate Paul’s overall message to the Thessalonian church.
