Matthew 6:22
I beg to differ.  The eye is the LENS of the body.   Our eyes enable us to see, focus, distinguish.  Light comes to us through our eyes.  Lamp vs Lens.  Both And?  Is there a difference?  If so, is the difference important?  Either way the more OPEN our eyes to the WORD and the WORLD, the more wholly, holy, and healthy we are living.
