2 Thes 3 is an exhortation to the faithful brethren of Thessalonica. Paul says the Lord continues to direct their hearts in the love of God and into the steadfastness of Christ. He directs them to "keep away from those who lead an unruly life " and not to associate with those who do not obey Paul's instruction. He exhorts such persons in the Lord Jesus and encourages the brethren to admonish them as brothers.
