“Your eye is a lamp that provides light for your body. When your eye is good, your whole body is filled with light. But when your eye is bad, your whole body is filled with darkness. And if the light you think you have is actually darkness, how deep that darkness is!” Matthew 6:22-23
The eye receives the light and through that light the activities of the body are directed.
What directs our moral and spiritual actions? Answer: our heart, our spirit, our conscience, our desires, our intentions, and our motives.
When our heart receives the light of God and the light of His Word, our eye is single, sound and healthy, and our actions are acceptable to God.
“Thine eye shall be single.” (KJV) The word “single” here means sound, wholesome, and healthy. The single or sound eye refers to purity of intention or selflessness in our motives.
With purity of motive our actions or the intentions of our activities will be full of light. With selfishness in our motive and insincerity in our intentions, we are termed to have an “evil eye” and our actions will be works of darkness.
“If therefore thine eye be single, thy whole body shall be full of light.”
When the eye is directed singly and steadily towards an object and is sound and healthy, everything is clear and plain. If the eye is not sound or healthy everything is dim or dark.
The eye regulates the motion and direction of the body. Walking through this world, it is important to fix our “eye”, our heart and affections on God in order to conduct ourselves righteously. Our conduct will be steadily righteous and acceptable to God when our motives are pure and we seek only the glory of God and the salvation of souls in all our actions.
Having our eye of faith single and unwavering “setting our affection on things above, not on things on the earth”, “setting our face like a flint” fixed on the glory of God, our actions and conduct will be approved of God.
All that is needful to direct our soul and conduct is that the eye of faith be fixed on God. Our motive must be pure and focused on God’s glory then will our life be holy and acceptable to God.
The eye that is full of light is a life lived by faith in the eternal promises of God. We may not be able to see the physical manifestation of those things, but we believe by faith in the truth that one day we will be with Jesus.
When our focus is on earthly temporal things, our sight is all blurred and messed up.
