I want you to notice, in the beautiful verses which speak of "light," that God does not at first tell us anything about Himself. He speaks to us of what He did when in the beginning He created the heaven and the earth, and of what He said at the time when the earth lay in darkness, buried beneath the waters. In the midst of the silence and darkness a voice was heard, the voice of God, "And God said, Let there be light: and there was light." This we read in the first page of God's Book; but it is very near its end that God makes it known that the One who made the light, the One at whose word light came from darkness, is Himself Light. It is His very Nature. "God is light." Now we learn from God's Word that there are two kinds of light, and two kinds of darkness; let us talk a little about this. We can well understand one kind of darkness, because we can see it: and we know it is caused by the absence of light. It grows dark when the sun, which makes our day, has set to us, and the night has come to wrap us round, as it were, in a curtain of shade that we may sleep quietly. It is dark too, not only by night, but all the day long in the deep caverns where the miner must carry his lamp to light up those dismal places where the sun never shines. This darkness, like that which rested upon the face of the deep before God spoke that word which brought the light, is caused by there being no light, and as soon as the light comes the darkness goes. The other kind of darkness we cannot see: it has to do, not with places, but with people, and we read about it very often in the Bible. It is that dreadful kind of darkness which has come through sin, and has settled down upon the heart of every one of us. This darkness God sees, and He speaks about it in His Word. We find it hard to believe that our hearts are all dark when God looks at them; that He finds no love to Himself there; no bright spot anywhere; but God, who is Light, as He looks straight down to the depths of those hearts, and sees us through and through, has told us the truth about ourselves, as He sees us. You do not like darkness better than light; the night better than the day, do you? I remember how sorry I used to be when night came, and how fond I was of saying to myself a verse I had learnt, as I lay awake in the early morning and watched the dawning light-- "I saw the glorious sun arise Far o'er yon mountain grey, And as he rode upon the skies The darkness went away; And all around me was so bright I wished it would be always light!" Yes, we naturally love the light which is so cheerful, and shows us so plainly all the beautiful things around us. But that other kind of light which shines from God into our hearts, do we like it?
