Conventional wisdom tells us that nothing is certain except death and taxes, but for most of us that is not enough. Wouldn't you like to be just as sure about where you stand with God? That's what the Thessalonians were looking for, and Paul's letters to them can help you find that assurance as well.
In the year A.D. 50, Paul entered Thessalonica while on his second missionary journey. He preached there for three weeks and was able to establish a church. However, a group of jealous Jews interpreted Paul's message to mean that he was proclaiming another ruler in opposition to the Roman emperor, and he was forced to leave town (Acts 17:1-10).
Because of Paul's concern for this young church, he sent his coworker, Timothy, to learn how the Thessalonians were doing. Timothy reported that the Christians' faith remained strong but that they continued to be persecuted by those who had banished Paul. Timothy also brought back questions which Paul had not had time to answer during his short stay.
First Thessalonians was Paul's first attempt at offering encouragement and answering questions—in fact it was probably the first of Paul's epistles. It was written from Corinth only a few months after Paul had left Thessalonica.
In 1 Thessalonians Paul offers encouragement in four major areas: (1) How can I be sure that I will be with Jesus after death? (2) How can I be sure that Jesus is coming again? (3) How can I be sure that Jesus hasn't forgotten me when I am suffering persecution? (4) How can I be sure that my life is pleasing to God?
Through your study of these letters, it is my hope that you will become sure of your faith and of your salvation and that, as a result, you will be able to "encourage each other with these words"(1Th 4:18).
