Now, we are called to follow Him; and in so doing, we have the assurance of His own word that we shall not walk in darkness, but shall have the light of life. Precious words!--"_the light of life_." Who can sound their living depths? who can duly estimate their worth? "The darkness is past, and the true light now shineth," and it is for us to walk in the full blaze of the light that shines along the pathway of the Son of God. Is there any uncertainty, any perplexity, any ground for hesitation here? Clearly not. How could there be if we are following Him? It is utterly impossible to combine the two ideas. And be it remarked here that it is not by any means a question of having a literal text of Scripture for every movement or every act. For example, I cannot expect to get a text of Scripture, or a voice from heaven, to tell me to go to London or to Edinburgh; or how long I am to stay when I go. How, then, it may be asked, am I to know where I ought to go, or how long I am to stay? The answer is, Wait on God, in singleness of eye and sincerity of heart, and He will make your path as plain as a sunbeam. This was what Jesus did; and if we follow Him, we shall not walk in darkness. "I will guide thee with Mine eye" is a most precious promise; but in order to profit by it, we must be near enough to Him to catch the movement of His eye, and intimate enough with Him to understand its meaning. Thus it is, in all the details of our daily life. It would answer a thousand questions, and solve a thousand difficulties, if we did but wait for divine guidance, and never attempt to move without it. If I have not gotten light to move, it is my plain duty to be still. We should never move in uncertainty. It often happens that we harass ourselves about moving or acting, when God would have us to be still and do nothing. We go and ask God about it, but get no answer; we betake ourselves to friends for advice and counsel, but they cannot help us, for it is entirely a question between our own souls and the Lord. Thus we are plunged in doubt and anxiety. And why? Simply because the eye is not single; we are not following Jesus, "the light of the world." We may set it down as a fixed principle, a precious axiom in the divine life, that if we are following Jesus, we shall have the light of life. He has said it, and that is enough for faith.
