This Little Light of Mine....and Luke, the Physician????

The other day Jenna was singing "this little light of mine" she kept on singing it over and over again when suddenly she just stopped and said "mommy, if I let my light shine this much, won't it run out of batteries?"
We are still reading through the Bible and we told Josh we would still be back in Luke soon. We mentioned that he was a physician or a doctor and he said "a doctor?" I said, sure, don't you think they needed doctors back then? "no," he said. Well, what would they do without a doctor? "back then they just died". (another moment that you had to be there....very serious, but I died laughing)
