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.
