Finally, brothers and sisters, whatever is true, whatever is noble, whatever is right, whatever is pure, whatever is lovely, whatever is admirable—if anything is excellent or praiseworthy—think about such things. Whatever you have learned or received or heard from me, or seen in me—put it into practice. And the God of peace will be with you.
Taken in context, Paul’s words here call us to a mindset that is uplifting, turning our attention to what in itself is wholesome and good. This has nothing at all to do with “the power of positive thinking,” or even “possibility thinking.” Nor does it have to do with shining our light into the darkness of this world. That will more or less naturally happen wherever we go as the light of the world in Christ. But yes, inevitably as we see the better way, we’ll see that the less better ways, or what we once thought to be good, or good enough must go. So it’s not like one has their head in the sand, either.
Sometimes Christians along with others see it as their moral duty to focus on all that’s wrong, the mess of the world with the goal of exposing and rooting it out, or at least taking a stand against it. There is surely a time to speak and a time to keep silent (Ecclesiastes 3:7b). But one can become completely absorbed in that, totally occupied with it, so that there’s no time to do what we’re called to do in the passage above. I liked what I heard Dallas Willard say online in a talk, that only after one has worked hard all day, and is collapsing should they turn their attention to the news. That might be an overstatement to make a point. It’s not like we’re to ignore what’s unpleasant. But neither should that be our focus. Instead we’re to concentrate on what’s uplifting and helpful to us. Then hopefully that same spirit and practice can help others as we continue to be helped. In and through Jesus.
