We have been told to let the light within us shine. God transforms one's soul, each with different gifts and abilities. All we need to do is say here I am Lord. When you live a life based on the light that's within you, it’s impossible for darkness to extinguish that light. If one considers the flashlight that goes dim and needs new batteries to give it new life. Your light shines because your prayers connect you to a power source which is Heavenly.
