"Your eye is the lamp of your body. If your eye is healthy, your whole body is full of light; but if it is not healthy, your body is full of darkness" (Luke 11:34).
I think as I reflect on this passage today, it reminds me of many other passages that focus on overall wholesome holiness for the physical and spiritual body. "Be holy for I am holy" (1 Pet.1:15) taken from Leviticus 11:44 just after God explains what foods are clean for consumption and unclean for consumption. Peter uses this passage in Leviticus to describe how believers should be holy in their conduct and to not conform to "former lusts." The eye is a very special and powerful organ; it can cause us to sin, however it is not the only organ of course involved in the various sins of this world. Jesus says that "if your right eye causes you to sin, pluck it out and cast it from you; for it is more profitable for you that one of your members perish, than for your whole body to be cast into hell" (Matt. 5:29). Jesus also talks of cutting off the right hand as well, which should make everyone sit up straight in their chairs. Why would Jesus suggest something so extreme? Jesus wouldn't in fact ask me to literally pluck out my eyes and cut off my hand? It is not the actual eye, but the thing that is causing my eye to sin. The cause is the thing that I must cut in order to have a more powerful and fulfilling relationship with God the Father.
The eye is powerful; we use it to see our world and the various things that are in our world either for good or for bad. It must be said that if we didn't have eyes, we wouldn't know what we would be missing, however, God gave us eyes to see our world. Could God have known that humans would use their eyes to lust, to greed, or to think evil thought? I believe that it would be harder to lust after something that we can't see, however, these thoughts begin with the heart whether we have eyes or not (Matt.15:19). I believe that in the beginning, God made Adam and Eve perfect. They didn't know that they were naked, therefore, they could not use their eyes to lust after each other. It was only until after they ate of the fruit of the tree of good and evil did they see that they were naked and felt ashamed. Why the shame unless it was not because of evil thoughts for one another? Therefore, we are capable of seeing with our eyes in a healthy manner because the first humans were capable before the fall. We can look at our world without desiring everything we see because God has given us His laws and Christ, the light of the world to help us overcome. We can use our eyes to say that something is evil or good, healthy spiritually or physically for our body. Our eye is the first organ to start an alarm system, such as "Hey, be careful." If our eyes are unhealthy or bad, our eyes won't give us that first warning before the sickness of sin moves onto another part of the body to make our body sicker and sicker. Our iniquities can separate us from God, so that He will not hear our prayers (Is.59:1-2). If our eyes are healthy, the whole body is healthy. It is the same for the body of Christ; if one member suffers, we all suffer (1 Cor.12:14-17). Every part of the body of Christ is important.
Therefore, are we using our first defence organ properly? Are we listening to what our eye has to tell us? Healthy eyes will make for a healthy body. The eye is the lamp of our body and it must "shine before men, so that they may see your good works and glorify your Father in heaven" (Matt. 5:16). The health of our body is dependent on our eyes. How does our body reflect the health of our eye? Does our body have self-inflicted marks? If our body does have self-inflicted marks, reflect on why you decided to place marks on your body. Does our body partake of ungodly activities or pleasures? Does our body have addictions that we cannot cut? Reflection on God’s word and prayer can help us to truly see the spiritual health of our bodies and lives. If we are willingly, God will open doors in order to help us escape our addictions, but first, let us first examine our eyes in order to determine the overall health of our body!
