Then Jesus spoke to them again, saying, “I am the light of the world. He who follows Me shall not walk in darkness, but have the light of life.” John 8:12
It is fun to see people switch on their phones’ flashlights and then hold up their phones at a concert or sporting event. A more biblical display of the power of light happens at Christmas Eve candlelight services. One candle lights another, then another, then another—until slowly the darkness in the auditorium is pushed back as the light spreads.
Darkness cannot prevent light from shining. Even the smallest light can enlighten a dark place—like a single candle in the depths of a pitch-black cave. In the beginning, Genesis tells us, “darkness was on the face of the deep” (1:2). That physical darkness was dispelled by the creation of the heavenly lights (Genesis 1:14-18). The apostle John builds on that theme to talk about the dispelling of spiritual darkness when Jesus came into the world. Jesus said He was the Light of the world, then told us we are as well (Matthew 5:14-16).
Your light matters in a dark world—shining alone and in concert with others. The darkness can never overcome the light of Christ in you.
Never doubt in the dark what God told you in the light. V. Raymond Edman
