Luke 11:33-36 ESV “No one after lighting a lamp puts it in a cellar or under a basket, but on a stand, so that those who enter may see the light. (34) Your eye is the lamp of your body. When your eye is healthy, your whole body is full of light, but when it is bad, your body is full of darkness. (35) Therefore be careful lest the light in you be darkness. (36) If then your whole body is full of light, having no part dark, it will be wholly bright, as when a lamp with its rays gives you light.”
These verses have always been hard to understand, even though we all sang “this little light of mine, I’m gonna let it shine” in Sunday School as children. That happens often by the way – children being taught songs and memory verses and so on without being helped to understand the meaning. And I maintain that children can indeed be taught quite deeper truths than we think. But then, that is another subject.
Jesus said “your eye is the lamp of your body.” You have to have a good eye or your body is going to wander around in the dark stubbing toes and so on.
Then Jesus moved to the real point here. He said, “therefore be careful lest the light in you be darkness.” What did He mean? I can tell you.
