33 “No one lights a lamp and then hides it or puts it under a basket. Instead, a lamp is placed on a stand, where its light can be seen by all who enter the house. 34 Your eye is a lamp that provides light for your body. When your eye is good, your whole body is filled with light. But when it is bad, your body is filled with darkness. 35 Make sure that the light you think you have is not actually darkness. 36 If you are filled with light, with no dark corners, then your whole life will be radiant, as though a floodlight were filling you with light.”
The lamp is Christ; the eye represents spiritual understanding and insight. Evil desires make the eye less sensitive and blot out the light of Christ's presence. If you have a hard time seeing God at work in the world and in your life, check your vision. Are any sinful desires blinding you to Christ? (LASB 10/30/12).
