1 Thessalonians

First Thessalonians is a letter from the apostle Paul, together with Silvanus (Silas) and Timotheus (Timothy), to the church at Thessalonica, the capital of Macedonia. Paul had founded the church on his second missionary journey (Acts 17) but was driven out by persecution after only a short stay. Written from Corinth around A.D. 50-51, it is one of the earliest books of the New Testament. When Timothy returned with good news of the Thessalonians' faith and love, Paul wrote this warm letter of thanksgiving and instruction.

The first half of the letter looks back: the gospel came to Thessalonica in power, the believers turned from idols to serve the living God, and their faith became an example to all Macedonia and Achaia. Paul defends the gentleness and integrity of his ministry among them, comparing himself to a nursing mother and an exhorting father. The second half looks forward, urging holiness and brotherly love, and answering an anxious question about believers who had died: the Lord himself shall descend from heaven, the dead in Christ shall rise first, and the living shall be caught up together with them.

First Thessalonians matters because it gives the church its clearest early teaching on the return of Christ, framing that hope not as speculation but as comfort. Its closing commands, rejoice evermore, pray without ceasing, in every thing give thanks, remain a pattern for daily Christian life.
