Psalms 119:105 Your word is a lamp to my feet And a light to my path.
John 8:12 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."
The Bible teaches that God is light, and in Him is no darkness at all. The ancient lamp, with its olive oil and wick, teaches us a valuable truth. There is something that exists called "darkness" and when there is no light we cannot see where we are going. But when there is "light" we can see the way ahead of us and know the direction that we are going.
God is light and His Word is light, He reveals Himself through His Holy Spirit and we can see the way that He has prepared for us.
