May the Lord make your love increase and overflow for each other and for everyone else, just as ours does for you. May he strengthen your hearts so that you will be blameless and holy in the presence of our God and Father when our Lord Jesus comes with all his holy ones. As for other matters, brothers and sisters, we instructed you how to live in order to please God, as in fact you are living. Now we ask you and urge you in the Lord Jesus to do this more and more. For you know what instructions we gave you by the authority of the Lord Jesus. It is God’s will that you should be sanctified: that you should avoid sexual immorality; that each of you should learn to control your own body in a way that is holy and honorable, not in passionate lust like the pagans, who do not know God; and that in this matter no one should wrong or take advantage of a brother or sister. The Lord will punish all those who commit such sins, as we told you and warned you before. For God did not call us to be impure, but to live a holy life. Therefore, anyone who rejects this instruction does not reject a human being but God, the very God who gives you his Holy Spirit.1 Thessalonians 3:12-4:8
God calls believers away from their sinful lives to a new lives dedicated to pleasing him. The Christian life, however, is rarely simple. We are caught between the desire to please God which is our supreme goal, and the temptations of our former sinful life. The process by which God purifies us is called “sanctification.” But what does sanctification look like? Are we required to do anything? If we are, what are we supposed to do? Join us as we learn from Paul’s instruction to the church at Thessalonica.
