"Then spake Jesus again unto them, saying, I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life."
Referring back to "yesterday's" scripture... Christ is who saves us from that dark and dreary waste. He is the tree... and when we follow him, we not only have light, but happiness as well. Light to illuminate the path, and happiness waiting for us at the tree. :) We don't have to have darkness in our lives... we just have to let the light in. Another side thought... does light *give* us life? is it part of what we are made of? :)
