The Unquenchable Light of Real Jesus

Lost in an underground cave system (way lost, way underground)...where's the light?  Falsey accused of stealing on the job and about to be fired...where's the light?  And which would you expect to share the power of that light: a "street preacher" or a "ratty tatty old woman" selling flowers she picked along the street (roses, dandelions, whatever).  Imagine her singing - and living - "This Little Light of Mine"!
