One summer I developed a problem with double vision. I went to the ophthalmologist and they did all kinds of tests and finally determined that I had what was called third nerve palsy. There was no treatment but they promised that most likely it would correct itself on its own. I ended up wearing an eye patch all summer long just so I could see without the double vision. I was so glad when it finally went away and my normal single vision was restored.
Jesus spoke about a similar problem that many people have. I would call it spiritual double vision. In Matthew 6:22-24 He speaks to us these words: “The light of the body is the eye: if therefore thine eye be single, thy whole body shall be full of light. But if thine eye be evil, thy whole body shall be full of darkness. If therefore the light that is in thee be darkness, how great is that darkness! No man can serve two masters: for either he will hate the one, and love the other; or else he will hold to the one, and despise the other. Ye cannot serve God and mammon”.
God's Word often uses the eye to represent the attitudes of the mind. If our eye is properly focused on God and doing His will, the body can function properly in its movements. But if our eye is out of focus and seeing double, it results in unsteady movements. We can’t make progress while trying to look in two directions at the same time. Jesus told us that we cannot serve God and money. Many people have double vision. They can’t make up their minds if they want to live a life of obedience to Christ or if they want to pursue the pleasures of the world. James tells us that a double minded man is unstable in all his ways.
My bout of double vision only lasted a summer. But many people live their whole lives with one eye on God and one eye on the world. If that is your problem go to the Great Ophthalmologist and ask Him to heal your spiritual double vision.
