Cloudy Vision

I have been struggling with cloudy vision for the past week. It is not because my vision is bad, but because there is a defect in the anti-glare coating on my glasses that has fogged them. It is difficult to read, to drive and to do daily functions that require vision.
This has made me think about my spiritual vision. What do we do to cloud our spiritual vision? We look at our problems, our lack of finances, our "wants", the faults of others, and other temporal things. When our eyes are set on these things our spiritual sight becomes cloudy and we don't see things as they really are. We become discontent or depressed or angry and can't see any solution to our problems.
We need to look up and see the Lord. He has all things in His hands. He knows all about our lives. He has all of the solutions to life's problems. God is able to give us a clear vision for our lives if we will just set our eyes on Him. He is all we need. When we focus on Christ, everything else becomes clear.
