“…Aspire to lead a quiet life, to mind your own business, and to work with your own hands, as we commanded you, that you may walk properly toward those who are outside, and that you may lack nothing” (1 Thess 4:11-12).
You can’t build a good testimony from what you are going to do. So, says the apostle, don’t look for glory; don’t meddle in other’s work; and don’t be slipshod in your own. That equals success.
