1 Thessalonians 3:12-4:2
New International Version - UK
12 May the Lord make your love increase and overflow for each other and for everyone else, just as ours does for you. 13 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.
Living to please God
4 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. 2 For you know what instructions we gave you by the authority of the Lord Jesus.
