When i think about light, i think about God. Just compare the three bible extracts below;
Genesis 1 (NIV)
1 In the beginning God created the heavens and the earth.
2 Now the earth was [a] formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters.
3 And God said, "Let there be light," and there was light. 4 God saw that the light was good, and He separated the light from the darkness. 5 God called the light "day," and the darkness he called "night." And there was evening, and there was morning—the first day.
ISAIAH 9.2
The people walking in darkness
have seen a great light;
on those living in the land of the shadow of death
a light has dawned.
John 9.3-5
3"Neither this man nor his parents sinned," said Jesus, "but this happened so that the work of God might be displayed in his life. 4As long as it is day, we must do the work of him who sent me. Night is coming, when no one can work. 5While I am in the world, I am the light of the world."
