Keep my eyes from what is false:

by your word give me life.

This is the prayer of one tempted to seek life and truth with the eyes rather than from the Word.  We live in an age dominated by images and the lustful eye.  We seek pleasures with our eyes, we seek truth in image, we glorify the physically beautiful.  The lust of our hearts is manifest by the gluttony of sight - our perverse desire to possess by seeing.  "The desire of the eyes comes not from the Father but from the world.  The love of the Father is not in those who love the world." (1 John 2.15-16)  The concupiscence of sight diminishes our capacity to receive the Word: it seeks knowledge from visual, exterior sources rather than instruction from the indwelling God.  As a result, the 'hypertrophy of visual curiosity' diminishes our most fundamental capacity: to contemplate. (Josef Pieper)

Many in our day covet physical health.  Yet how many speak of the health of the eyes as indicating a spiritual condition?  Jesus did precisely this when he said "if your eye is healthy your body will be full of light; if it is unhealthy your body will be full of darkness." (Matthew 6.22-23)  Perhaps the most common manifestation of an unhealthy eye is one which gazes lustfully on one who is not one's spouse.  But even more pervasive and insidious is the countless hours spent daily before the "great blinking eye" of the television.  One of the many problems of living in this age of visual curiosity is that we begin to measure spiritual realities with the yardstick of external stimuli.
