It’s the 8th chapter in A Godward Heart, and it’s centered in Luke 11:33-36 where Jesus uses the phrase “. . . less the light in you be darkness . . .” Curious.
Be Careful, Lest the Light in You be Darkness
Luke 11:33-36
“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. 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. Therefore be careful lest the light in you be darkness. 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.”
So Doctor Piper comments:
“Be careful!” he said. This is the only imperative in the text. Be careful what you see! Be careful what you regard as bright and attractive and compelling. If it is not Christ, you will be filled with darkness, no matter how bright it seems for a season. Candles seem bright until the sun comes out. Then they are useless . . .”
Christ is the glory we were made to see. His light alone will fill us and give the light of life and meaning to every part of our lives. And when that happens, we ourselves will shine and give off the rays of Christ. ‘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’ (v. 36).”
A Godward Heart, 31.
Let’s commit ourselves to having “healthy eyes” that the world might see the light of Christ in us every time they look at us. And let us “be careful” just as Jesus commanded us lest the light that He gives us becomes a darkness to promote ourselves rather than the Christ who redeems us.
