John 8:12 (ESV)
12 Again Jesus spoke to them, saying, �I am the light of the world. Whoever follows me will not walk in darkness, but will have the light of life.�

There is a sun that illuminates the world and takes away the darkness. There is also the Son of God that illuminates the lives of people and takes away the darkness they walk in. The visible light of the world is the sun, and Christ is the Sun of righteousness.

I am the light of the world, the founder of the Christian religion said. What a stupendous phrase! And how particularly marvelous today, when one is conscious of so much darkness in the world! Let your light shine before men, he exhorted us. You know, sometimes ... someone asks me what I most want, what I should most like to do in the little that remains of my life, and I always nowadays truthfully answer--and it is truthful--"I should like my light to shine, even if only very fitfully, like a match struck in a dark, cavernous night and then flickering out." [Malcolm Muggeridge in Jesus Rediscovered. Christianity Today, Vol. 41, no. 11]

Many of us become so wrapped up in our own issues, problems and daily routine that we forget there are those wandering lost in a dark world. There are many who do not know the love, mercy, and grace of God. They don�t understand the concept of salvation that brings them eternal life with God in heaven.

Jesus Christ said He is the light of the world. Jesus Christ came to reconcile man with God by providing light on the word of God that man could clearly see.
