What does 1 Thessalonians 4:1 mean?
The term "finally" in this verse introduces the final section of 1 Thessalonians. Here, Paul presents his final instructions and information. This section runs through chapters 4 and 5. Prior passages were mostly a description of the Thessalonian believers' spiritual growth and their excellent reputation.Here, Paul gives his readers an urgent reminder about what he had once told them in person. He stresses the importance of this teaching by citing Jesus as the authority for his words. Paul taught the Thessalonians how to walk and lead a life that pleases God. They were heeding his instructions, but needed to continue doing so. Paul's message is meant to both encourage and motivate.
The Christian life is not a single step which instantly brings a believer to spiritual maturity. Rather, it is a lifelong walk. The Bible describes how Christians are supposed to follow this path. Romans 13:13 commands us to "walk properly as in the daytime." Galatians 5:16 and 25 exhort us to "walk by the Spirit." Ephesians 5:2 commands us to "walk in love." Ephesians 5:8 tells us to "walk as children of light." We are to walk in Christ (Colossians 2:6). And Colossians 4:5 instructs us to "walk in wisdom toward outsiders." These kinds of walks last until we see Jesus face to face.
