About 2 generations ago you’d pull into a gas station and be greeted by an attendant who, among other things, would ask, "Check yer oil?" If you ended up being low they'd whip out a quart and top you off. Sounds a little quaint but brings to mind a crucial Christian issue. Jesus told a parable about 5 young ladies who should have checked their oil and regretted it later. It’s not about engine oil, but lamp oil. Finding one’s way in the dark required a lamp, and a lamp required oil. When the lamp runs out of oil, you are in the dark. Jesus uses oil as an analogy for faith. Have you checked your level lately?
