1 Thessalonians 4:9-12

9Now concerning brotherly love, you have no need for anyone to write you, for you have been [personally] taught by God to love one another [that is, to have an unselfish concern for others and to do things for their benefit].

10For indeed you already do practice it toward all the believers throughout Macedonia [by actively displaying your love and concern for them]. But we urge you, brothers and sisters, that you excel [in this matter] more and more,

11and to make it your ambition to live quietly and peacefully, and to mind your own affairs and work with your hands, just as we directed you,

12so that you will behave properly toward outsiders [exhibiting good character, personal integrity, and moral courage worthy of the respect of the outside world], and be dependent on no one and in need of nothing [be self-supporting].
