When my two nieces were younger, they’d coax me into a game after dinner. They’d turn off all the lights in the house, and we’d shuffle through the darkness, clutching each other and laughing. They enjoyed scaring themselves by choosing to walk in the dark, knowing they could turn on the light anytime.

In his letter to the early believers in Jesus, the apostle John talked about choosing to walk in a different kind of darkness. First John 1:6 refers to sin as “darkness.” Walking in darkness isn’t a momentary lapse, but a choice to keep engaging in wrongdoing. John reminds us that our holy God “is light” and “in him there is no darkness” (v. 5). So when we claim a relationship with Him yet willfully continue sinning, “we lie and do not live out the truth” (v. 6). Jesus, the light of the world, came so that “whoever follows [Him] will never walk in darkness but will have the light of life” (John 8:12 ).

By God’s grace, after we’ve wandered in spiritual darkness and we turn to Him in repentance, we can walk in His light again—in His ways and purposes. He will “forgive us our sins and purify us from all unrighteousness” (1 John 1:9). Only when we live in obedience to God can we enjoy the full blessing of relationship with Him and with other believers (v. 7).
