It's easy to see that we live "in the midst of a crooked and perverse generation" (Phil. 2:15). We are continually reminded that we live in a fallen world by our own sinful tendencies, by newspaper headlines that report horrifying crimes, and by a society that is growing accustomed to gross immorality.

Against this backdrop of darkness, followers of Jesus are told to be "lights in the world" (Phil. 2:15). Yet our conduct often reflects a dim and distorted image of Him. That's why Paul warned us against "complaining and disputing" (v.14) and urged us to put our salvation to work with reverence for God (vv.12-13).

We may wonder why the apostle didn't mention something more scandalous than complaining. But relatively few of us are guilty of "headline" sins, while all of us have been guilty of the smugness, pride, and self-centeredness that erupts in murmuring and quarreling. And these "lesser" sins can be just as destructive.

Paul knew that we need to be spiritually alert to evil and nip it in the bud. By heeding these exhortations we will "become blameless and harmless, children of God without fault" (v.15). Then we will be sure to shine as lights in this dark world.  — Herbert Vander Lugt
