If someone can’t mind their own business, it may be due to a small mind and not any business of their own.
Gossip and laziness are closely related. Lazy people love to talk about others and stick their noses into other people’s business. And if you run across someone who talks a lot about others (one of those “Can you keep a secret?” types), it’s likely that person isn’t very productive with his or her time.
Christians can get (and deserve) a bad reputation by being lazy gossips. Do you want to improve the perception of Christians and bring honor to God in the process? Then work hard, keep to your own business, and never get tired of doing good. This isn’t just good advice. It is what God wants you to do.
Yet we hear that some of you are living idle lives, refusing the work and wasting time meddling in other people’s business. In the name of the Lord Jesus Christ, we appeal to such people–no, we command them: Settle down and get to work. 2 Thessalonians 3:11-12
