In this sermon From No Light To No Night, The Bible refers to a life of righteousness and godliness as a life of LIGHT. The Bible often uses things of the world to represent something, like waters to represent people. The WORD created all things, and here we see that the WORD is Jesus Christ. That WORD was the light of all men. You must come to Jesus, for He is the WORD of God saying, "Let there be light." When God said, "Let there be light" He was saying, "Let there be a Saviour, called Jesus Christ."  He shone in darkness. After He shone, It was as if he said "Let there be fresh water". Since waters, or people, were separated.
