"The eye is the lamp of the body. If your eyes are healthy, your whole body will be full of light. But if your eyes are unhealthy, your whole body will be full of darkness. If then the light within you is darkness, how great is that darkness." - Matt 6:22
I once read that whatever enters our system through our senses creates an image in our minds, setting into motion a series of thoughts. These thought trigger emotions, which spark-off actions, resulting in a series of consequences. The "war of images" has never been more profound than in our day and age, leaving most of us feeling very vulnerable and at the mercy of anything that the digital world throws at us.
I do not think it insignificant that the very next verse calls us to make a decision; "No one can serve two masters. Either you will hate the one and love the other..." At some point in our lives we all need to decide what we truly love and what we truly hate. In which direction will we allow our minds to be lured? When it comes to deciding what is nourishing to the soul and what sets us up to discern God's will for our lives, the answer is more straight-forward than what our complex world-views would have us believe. The only question remaining is this one: "Do we really know what we love?"
