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 within thee be darkness, how great is that darkness!

1.FROM those which are commonly termed religious actions, and which are real branches of true religion, where they springfrom a pure and holy intention, and are performed in a manner suitable thereto, our Lord proceeds to the actions of common life, and shews that the same purity of intention, is as indispensably required in our ordinary business, as in giving alms, or fasting, or prayer.

And without question the same purity of intention, “which makes our alms and devotions acceptable, must also make our labour or employment, a proper offering to God. If a man pursues his business, that he may raise himself to a state of figure and riches in the world, he is no longer serving God in his employment, and has no more title to a reward from God, than he who gives alms that he may be seen, or prays that he may be heard of men. For vain and earthly designs are no more allowable in our employments, than in our alms and devotions. They are not only evil when they mix with our good works,” with our religious actions, “but they have the same evil nature when they enter into the common business of our employments. If it were allowable to pursue them in our worldly employments, it would be allowable to pursue them in our devotions. But as our alms and devotions are not an acceptable service, but when they proceed from a pure intention, so our common employment cannot be reckoned a service to him, but when it is performed with the same piety of heart.”

2. This our blessed Lord declares in the liveliest manner, in those strong and comprehensive words which he explains, inforces and inlarges upon, throughout this whole chapter. 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. The eye is the intention: what the eye is to the body, the intention is to the soul. As the one guides all the motions of the body, so does the other those of the soul. This eye of the soul is then said to be single, when it looks at one thing only; when we have no other design, but to know God, and Jesus Christ whom he hath sent: to know him with suitable affections, loving him as he hath loved us: to please God in all things: to serve God (as we love him) with all our heart and mind and soul and strength: and to enjoy God in all and above all things, in time and in eternity.

3. If thine eye be thus single, thus fixed on God, thy whole body shall be full of light. Thy whole body,—All that is guided by the intention, as the body is by the eye. All thou art: all thou dost: thy desires, tempers, affections; thy thoughts and words and actions. The whole of these shall be full of light: full of true, divine knowledge. This is the first thing we may here understand by light. In his light thou shalt see light. He which of old commanded light to shine out of darkness, shall shine in thy heart. He shall enlightenthe eyes of thy understanding, with the knowledge of the glory of God. His Spirit shall reveal unto thee the deep things of God. The inspiration of the Holy One shall give thee understanding, and cause thee to know wisdom secretly. Yea, the anointing which thou receivest of him, shall abide in thee and teach thee of all things.

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 byday, 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, enjoyingwhatever is the will of God concerning him in Christ Jesus.
