Light
Genesis 1:14-19
And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs…


I. ITS SPEED! Have you any idea of it? The mind becomes confused when we try to imagine it. For instance, whence, think you, came the bright rays which this very morning lighted up your room with their dazzling brightness? Ah! they had travelled very far before they reached you, even all the distance between the sun and the earth. If a man could take the same journey, travelling at the rate of ninety-five miles a day, he would take a million of days, or nearly three thousand years to do it. And yet, how long do you think those bright rays have been in travelling this morning from the sun to your window? Only eight minutes and thirteen seconds.

II. But if you wonder at the speed of light, what will you say when you think of its ABUNDANCE? This is, if possible, still more wonderful. Who can even imagine the immense and immeasurable torrents of light which from age to age have gushed forth from the sun in every direction, constantly filling with their ceaseless waves the whole extent of planetary space? I do not speak thoughtlessly when I tell you of the ceaseless flow of these waves of light, for they gush forth from the sun by night as well as by day. Some young people fancy that when it is night with us, it is then night in the universe; but this is a childish fancy, for, on the contrary, there is perpetual day in the wide universe of space.

III. ITS BRILLIANT COLOURS. The rays of light which come to us directly from the sun, are, you know, of a dazzling white. If you shut carefully all the shutters in your room, so as to make it perfectly dark, and if you allow a single ray of light to enter through a small hole, you will see it mark on the opposite wall a beautiful circle of white light. But do you know what would happen to this ray if you were to place before the hole a prism of finely polished glass? When the great Newton tried this experiment for the first time, he tells us that he started with joy. The sight that he saw, and that you would see, would be this: The prism would decompose and divide the beautiful white ray into seven rays, still more beautiful, of bright-coloured light, which would paint themselves each separately on the wall, in the following order: violet, indigo, blue, green, yellow, orange, red. These brilliant-coloured rays, of which each white ray is made up, are reflected in various ways, according to the nature and composition of different bodies, and thus they give their varied and manifold tints to all objects in nature.
