How does experience confirm this? Even after God hath opened the eyes of our understanding, if we seek or desire any thing else than God, how soon is our foolish heart darkened? Then clouds again rest upon our souls. Doubts and fears again overwhelm us. We are tossed to and fro, and know not what to do, or which is the path wherein we should go. But when we desire and seek nothing but God, clouds and doubts vanish away. We _who were sometime darkness, are now light in the_ Lord. The night now shineth as the day; and we find, _the path of the upright is light_. God sheweth us the path wherein we should go, and _maketh plain the way before our face_. 4. The second thing which we may here understand by _light_, is holiness. While thou seeketh God in all things, thou shalt find him in all, the fountain of all holiness, continually filling thee with his own likeness, with justice, mercy and truth. While thou lookest unto _Jesus_ and him alone, thou shalt be filled with the mind that was in him. Thy soul shall be renewed day by day, after the image of him that created it. If the eye of thy mind be not removed from him, if thou endurest _seeing him that is invisible_, and seeking nothing else in heaven or earth, then as thou beholdest the glory of the Lord, _thou shalt be transformed into the same image, from glory to glory, by the Spirit of the_ Lord. And it is also matter of daily experience, that _by grace we are_ thus _saved thro’ faith_. It is by faith that the eye of the mind is opened, to see the light of the glorious love of God. And as long as it is steadily fixed thereon, on God in _Christ_, reconciling the world unto himself, we are more and more filled with the love of God and man, with meekness, gentleness, long-suffering; with all the fruits of holiness, which are thro’ _Christ Jesus_, to the glory of God the Father. 5. This light which fills him who has a single eye, implies, thirdly, happiness as well as holiness. Surely _light is sweet, and a pleasant thing it is to see the sun_. But how much more to see the Sun of Righteousness, continually shining upon the soul? And if there be any consolation in _Christ_, if any comfort of love, if any peace that passeth all understanding, if any rejoicing in hope of the glory of God, they all belong to him whose eye is single. Thus is his _whole body full of light_. He walketh in the light as God is in the light, rejoicing evermore, praying without ceasing, and in every thing giving thanks, _enjoying_ whatever is the will of God concerning him in _Christ Jesus_. 6. _But if thine eye be evil, thy whole body shall be full of darkness. If thine eye be evil_: We see there is no medium between a single and an evil eye. If the eye be not single, then it is evil. If the intention, in whatever we do, be not singly to God, if we seek any thing else, then our _mind and conscience are defiled_.
