1 Thessalonians 4:9-12
New American Standard Bible (NASB)
9 Now as to the love of the brethren, you have no need for anyone to write to you, for you yourselves are taught by God to love one another; 10 for indeed you do practice it toward all the brethren who are in all Macedonia. But we urge you, brethren, to excel still more, 11 and to make it your ambition to lead a quiet life and attend to your own business and work with your hands, just as we commanded you, 12 so that you will[a]behave properly toward outsiders and [b]not be in any need.
How often do we complain about coworkers or about an injustice that has been done towards us by our boss? What about feeling like we deserve a break, others don't work as hard as us, gossip in the name of asking for advice, or search facebook statuses looking for the next piece of good gossip err sorry "information" or "keeping in touch". Do we start sentences with "did you hear about....." If you find yourself saying "I probably shouldn't tell you this but..." but nothing, shut it (and trust me I fail at this). To me all these things are what is talked about in II Thessalonians 3:6 (look it up), it says stay away from people who live an unruly/undisciplined life, 3:11 actually uses the word "busybodies" in the NASB.
We do all kinds of things to set are selves apart from the world, but what about living a quiet life(Prov 17:28 Even a fool is considered wise when he shuts his mouth)? Verse 11 says make it your ambition to lead a quiet life and then verse 12 says people who don't know Jesus (outsiders) will be watching, so what are they seeing (Col 4:5)?
2 Thessalonians 3:13
New American Standard Bible (NASB)
13 But as for you, brethren, do not grow weary of doing good.
Make it your ambition....
