1 Thessalonians 4:1, 12

Finally, believers, we ask and admonish you in the Lord Jesus, that you follow the instruction that you received from us about how you ought to walk and please God (just as you are actually doing) and that you excel even more and more [pursuing a life of purpose and living in a way that expresses gratitude to God for your salvation].

so 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].
