1 Thessalonians 3:12-4:2 New Revised Standard Version Catholic Edition (NRSVCE)
12 And may the Lord make you increase and abound in love for one another and for all, just as we abound in love for you. 13 And may he so strengthen your hearts in holiness that you may be blameless before our God and Father at the coming of our Lord Jesus with all his saints.
A Life Pleasing to God
4 Finally, brothers and sisters,[a] we ask and urge you in the Lord Jesus that, as you learned from us how you ought to live and to please God (as, in fact, you are doing), you should do so more and more. 2 For you know what instructions we gave you through the Lord Jesus.
