The story of Chanukah centers around the eternal flame in the Temple, the light that was never to go out, and how, once the Jews were able to return to their ruined and desecrated Temple, they were able to find a bit of consecrated oil to re-light that flame. That oil burned and burned, far longer than seemed possible, and the flame that had gone out offered the possibility of eternity once more.
When have you found the ability or resources to keep a light burning when it seemed inevitable that it would go out?
