John 1:15 "In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things came into being through him, and without him not one thing came into being. What has come into being in him was life, and the life was the light of all people. The light shines in the darkness, and the darkness did not overcome it."
Psalm 119:105 "Your word is a lamp before my feet and a light for my journey."
The light is Jesus and the Bible is the story of Jesus. If you wish to know Him better than read His story. It will change your life.
