That Christ is the Light, and the True Light, is a truth dear to every Christian. He coming into the world manifests every man. Rich or poor, simple or sage, false or faithful, not one escapes His all-searching light. Nor is there the least circumstance in the course of every day, any more than in what pertains to God, and truth, and morals, not for this life only but for eternity, that He does not set in the light of God. Only through Him do we see fully what God is, Satan, man, the sinner, the saint, heaven, hell, everything.
The disciples, as the Lord told them in Matt. 5:14, are the light of the world, as they are also the salt of the earth (13). They could be neither apart from Christ. It is He who thus assimilates them to Himself; the latter in His character of righteousness, the former in the quality of His grace, as already explained in Series xi. 4. In receiving Him by faith they receive a new nature, being born of God; hence there is both righteousness and love in their ways.
But here there is a further though connected truth of great value.
“The lamp of the body is the eye; if therefore thine eye be single, thy whole body will be light; but if thine eye be wicked, thy whole body will be dark. If therefore the light that is in thee is darkness, how great the darkness”
It is a question not of the light, which is perfect but of “the eye.” Spiritual condition has an immense deal to do with the disciples seeing aright. Our recipiency and discernment, our actual judgment and our practice, depend on the state of our affections. The Lord presents the ready and effectual test. “If therefore thine eye be single, thy whole body will be light; but if thine eye be wicked, thy whole body will be dark.”
Christ truly the object before one gives singleness of eye; and where He is simply and exclusively the “one thing” before the soul, the whole body is light. Difficulties vanish. The will of God becomes quite clear. I am surprised and ashamed to have had doubts here and uncertainty there. I recognize to my humiliation that I had been asleep in my ways and had to rise up from among the dead, and then only have Christ shining upon me.
Prayer alone does not ensure singleness of eye, nor yet suffices searching the word accompanied by prayer. There may be a fleshly film that dims the eye. We are too apt to think ourselves of importance for God when it is all of grace that He uses us in this way or that. We fail to appreciate our Lord’s waiting on His Father, without taking a single step till He gets the word. Yet it is to His obedience that we are sanctified by the Spirit.
We are not like Jews with every point great or small religiously and in ordinary life, in peace or in war, personal, domestic, or social, all ruled by the statutes and ordinances, prohibitions and injunctions of law. Christ brought in the fuller and deeper obedience of a Son, and makes it by grace the believer’s by the gift of life eternal and eternal redemption, with the Holy Spirit indwelling as power and personally also in us. But though thus blessed, there are still the three great enemies, the flesh, the world, and the devil, in the face of which we are responsible to please God as His children. We need therefore to pray, as the apostle did for the Colossians, to be filled with the right knowledge of His will, in all wisdom and spiritual understanding, to walk worthily of the Lord unto all well-pleasing, bearing fruit in every good work, and growing by the right knowledge of God (Col. 1:9, 10).
For this we need the eye single and the whole body light. How is this to be? The Lord tells us in John 15:7: “If ye abide in Me, and My words abide in you, ye shall ask what ye will, and it shall be done to you.” Habitual dependence on Him with confidence in His love is to abide in Him: without this all else is vain. But where we abide by grace, His words are needed to direct: for who is sufficient otherwise? and His Spirit is given to guide us thus. Only thus are we sure that we have His mind; for thus the eye is single and the whole body light. Then when we ask, we have our petition. O that so it may be and that we may be content with nothing less!
What is the issue, where other objects are allowed? The alternative is, “If thine eye be wicked, thy whole body will be dark.” How solemn the sentence, and how true! “If therefore the light that is in thee be darkness, how great the darkness!” O look to God that it be not so with you, a disciple of the Lord!
See too the impossibility of the Light yours, of the eye single, save by genuine repentance toward God and faith in our Lord Jesus. Doubt yourself, not God; and receive Him who in His grace came to receive you by faith, if you have not already done so.
