14 Do all things without complaining and disputing, 15 that you may become blameless and harmless, children of God without fault in the midst of a crooked and perverse generation, among whom you shine as lights in the world, 16 holding fast the word of life, so that I may rejoice in the day of Christ that I have not run in vain or labored in vain (Philippians 2:14–16, NKJV).
Just as the influence of light removes darkness, Christians diffuse sin’s darkness when we “do all things without complaining and disputing” (v. 14). We are to live in peaceful unity, maintaining the mind of Christ (Phil. 2:1-8). By doing so, we avoid “complaining” (grumbling, murmuring against others, James 5:9) and “disputing” (arguing over words that ruin the hearers instead of strengthening them, 2 Tim. 2:14; 1 Tim. 1:3-4). Like the first century saints, we live in the middle of a generation that is immoral, “crooked” (warped), and “perverse” (distorted, corrupt). By contrast, children of God are “lights in the world,” refusing to participate in sin with the world (v. 15). We are to be (1) Blameless (free of censure, 1 Thess. 3:13), (2) Harmless (“unmixed,” guiltless, Rom. 16:19), and (3) Without fault (unblemished, blameless, not needing a reprimand, 2 Pet. 3:14). Christians are lights in this dark, sinful world. Do not extinguish your light (influence) by becoming part of the problem, sinning with the world. Like the Philippians, we will be victors when Christ returns if we hold “fast the word of life” delivered by the apostles of Christ (v. 16; 1 John 5:3-4).
