John 3:19-21, 8:12; 1 John 1:5-7
Before a person believes in Jesus, he is like a man walking in the dark. He stumbles and often falls into sin, because he has no light to guide him. When we trust in the Lord Jesus, we become like a man walking on a straight road on a sunny day! Jesus said, "I am the Light of the world. If a man follows Me, he will not walk in darkness." God gives His Holy Spirit to help and teach all believers His way of life.
