Jesus talks about the heart and then talks about the eye.
22 “The eye is the lamp of the body; so if your eye is clear [spiritually perceptive], your whole body will be full of light [benefiting from God’s precepts]. 23 But if your eye is bad [spiritually blind], your whole body will be full of darkness [devoid of God’s precepts]. So if the [very] light inside you [your inner self, your heart, your conscience] is darkness, how great and terrible is that darkness! Matthew 6:22-23
I really think the Amplified Version, by including meanings within the text, does a great job of defining the meaning of this verse.
I can’t help but think about this study being a part of “correcting the vision” of our eyes. We’ve come to a place where we are fixing our eyes upon man: preachers, teachers, presidents, congressmen, actors, and even fictional characters instead of on Jesus. The point to this whole study is to get back to basics – refocus our vision – and only look at what Jesus had to say.
Are you letting a little more light in? I sure am.
As a little added study on it though:
Robertson’s Word Pictures adds:
We see double and confuse our vision. We keep one eye on the hoarded treasures of earth and roll the other proudly up to heaven. Seeing double is double-mindedness as is shown in Mat_6:24.
Albert Barnes illustrates with:
The sentiment stated in the preceding verses – the duty of fixing the affections on heavenly things – Jesus proceeds to illustrate by a reference to the “eye.” When the eye is directed steadily toward an object, and is in health, or is single, everything is clear and plain. If it vibrates, flies to different objects, is fixed on no one singly, or is diseased, nothing is seen clearly. Everything is dim and confused. The man, therefore, is unsteady. The eye regulates the motion of the body. To have an object distinctly in view is necessary in order to correct and regulate action. Rope-dancers, that they may steady themselves, fix the eye on some object on the wall, and look steadily at that. If they should look down on the rope or the people, they might become dizzy and fall. A man crossing a stream on a log, if he will look across at some object steadily, will be in little danger. If he looks down on the dashing and rolling waters, he will become dizzy, and fall. So Jesus says, in order that the conduct may be right, it is important to fix the affections on heaven. Having the affections there – having the eye of faith single, steady, unwavering – all the conduct will be correspondent.
