What does John 3:20 mean?
Light is an important symbol in the Bible. Jesus is described as "the Light" in several passages (John 1:9, 19). Light reveals things, and some of what it uncovers we would rather keep a secret. Those who commit sin would prefer that sin stay hidden, and not be exposed.The Greek term here translated as "evil," or "wicked," is phaula, which also means "worthless," "base," or "no good." A life without God may seem satisfying for a while (Hebrews 11:25). But it's ultimately hopeless, worthless, and ends in disaster (Mark 8:36; Proverbs 8:35–36). This is not just a Christian opinion. Many atheists grudgingly subscribe to this idea, as well. They seek ways to avoid living as though life has no meaning but recognize that without God there is no sensible purpose to life. To live a life of purpose, rationally, a person must believe in purpose.
