Jesus announced that he was the light of the world. He was this at many levels.
He lived a life that threw healing light on the darkness of hopelessness and illness.
His light of truth-speaking exposed the hypocrisy of religious traditions in his day. Traditions which allowed, for instance, a donkey to be released from its stall on the sabbath for a drink of water, but condemned freeing a sick woman from a long-standing illness on the sabbath.
His light of insight into what life is really about, still blinds materialism with its encouragement to love your enemies, be honest, pure, fair, generous; not to judge.
Fast forward to contemporary culture with its poor still struggling to survive. A man shares a simple and brilliant (pun intended) solution to literally shine light into the homes of people who cannot afford electricity.
I think Jesus would be pleased.
