Matthew 6:22-23 (KJV) 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!
This is true in both the physical and spiritual realm, but the Lord Jesus is speaking of spiritual matters. The subject is the same as before – treasures. To fix the eye on something is to desire it. Good spiritual eyes see things as they are and desire the glory of God, the things of the kingdom of light, and the eternal rewards He gives to those who serve Him. Bad spiritual eyes do not see things as they really are, and desire the things of time, the things related to sin, self, and darkness. They see no glory of Christ and no value in salvation.
The direction in which the eyes of our mind and heart look determines whether we will be filled with God’s light or the darkness of sin. There are only two possible kinds of vision – that which is set on the things of this world, or that which is set on the things of heaven. God will hold us responsible for where we keep our eyes.
What we see has such a great impact on our inner being. And what we choose to look at, even more so. When our eyes feed our lust and greed, the darkness of envy grows within us. But when we look with wonder at God’s handiwork, or with compassion on God’s children, His light fills us and radiates from us.
