Eyes let in the light

Luke
Today I read about the story of how the eye is like a lamp, and when the eye lets in good light, the whole body is good, and when it lets in darkness, the whole body is dark (Luke 11:34).  Some commentaries try to liken the eye of the body to the eye of understanding.  To some degree, that is okay.  But I think we could just let the eye be the eye in this story.  For example, when you look on good things in life, and revel in nature, you can be drawn to God because you see the work of his hands.  When you read the bible, you're letting in light.   These sorts of visual activities bring light into the body.  But when you watch trash on TV, or see bad movies, or read inappropriate things, or go see inappropriate things, you're letting darkness in.  So we must make sure we let our eyes rest on the things of God, and that leads to bringing in more and more light to our understanding.  It's a tough thing to keep our eyes pure today, but we've got to rise to the challenge.
