Matt. 6:22,23 ¶ The eye is the lamp of the body. So, if your eye is healthy, your whole body will be full of light, but if your eye is bad, your whole body will be full of darkness. If then the light in you is darkness, how great is the darkness!
I love the teaching of Jesus, so simple a child can understand His words yet so profound that the scholars stumble over His message. In today’s verse Jesus is in the middle of a teaching on the Lord’s provision. He reminds His followers about the Father’s love for all of His creatures and how He lavishes His provision daily on all of His creation. He said that if the Father provides for His creatures how much more will He provide for His sons and daughters. So what do our eyes have to do with anything? This is the point, He is talking about spiritual vision and the focus of our love. If our affection and vision is focused on the things of this world our life is filled with darkness. If our affection is on Him, our whole being is filled with light. As a result we know our God will provide for us. Secondly, we will love His kingdom and want to invest our lives and our resources in His work. Here is how Albert Barnes describes this passage.
“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 singly and steadily towards 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 to correct and regulate action. 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.”
So that is just the way Jesus is, simple yet deeply profound. So, what is your “eye” fixed on? What is the object of your joy and affection? Answer those questions and you will find the condition of your soul.
