And this is made still more plain and certain by the next word in the text: “Christ shall _give_ thee light:” not sell thee light, or allow thee to find light after great struggles, and weary years of study: but, _give_ thee light. Give it thee of His free grace and generosity. We might have expected that, merely from remembering to whom the light belongs. The mere fact that light belongs to the Lord Jesus Christ, who is the express likeness of His Father, might have made us sure that He would give His light freely to the unthankful and to the evil, just as His Father makes His sun to shine alike on the evil and on the good. Therefore this text does not leave us to find out the good news for ourselves. It declares to us plainly that He will give it us, as freely as He gives us all things richly to enjoy. But, someone will say: You surely cannot mean that we shall have understanding without study? You cannot mean that we are to become wise without careful thought, or that we are to understand books without learning to read? Of course not, my friends. The text does not say: “Christ will give thee eyes; Christ will give thee sense:” but, “Christ will give thee light.” . . . Do you not see the difference? Of what use would your eyes be without light? And of what use would light be if your eyes were shut, and you asleep? In darkness you cannot see. Your eyes are there, as good as ever; the world is there, as fair as ever: but you cannot see it, because there is no light. You can only feel it, by groping about with your hands, and laying hold of whatsoever happens to be nearest you. And do you think that though your bodily eyes cannot see, unless God puts His light in the sky, to shine on everything, and show it you, yet your minds and souls can see without any light from God? Not so, my friends. What the sun is to this earth, that the Lord Jesus Christ, the Word of God, is to the spirit—that is, the reason and conscience—of every man who comes into the world. Now, the good news of holy baptism is, that the light is here; that God’s Spirit is with us, to teach us the truth about everything, that we may see it in its true light, as it is, as God sees it; that the day-spring from on high has visited us, to give light to those who sit in darkness and in the shadow of death, to guide our feet into the way of peace; and that we are children of the light and of the day. But what if those who sit in darkness like the darkness; and wilfully shut their eyes tight that they may not see the day-spring from on high, and the light which God has sent into the world? Then the light will not profit them, but they will walk on still in darkness, not knowing whither they are going.
