In him was life, and that life was the light of men. The light shines in the darkness, but the darkness has not overcome it.
(John 1:4-5, New International Version)
Life! Not just living, but true, genuine life. Life that gives us light that darkness cannot steal away. That's why God sent Jesus! Thankfully that light still shines and all of Satan's horses and all of Satan's men cannot put their deepest darkest darkness together again! Hallelujah!
