"God is light, and in him is no darkness at all"

There are more than 200 references to the word 'light' in the Bible.

Light was the first of God's creations, according to the book of Genesis.

  And God said, let there be light, and there was light. (Old Testament, Genesis, i,3.)
God saw that the light was good, and he separated the light from the darkness. (Old Testament, Genesis, i,4.)
  To the land of deepest night, of deep shadow and disorder, where even the light is like

  darkness. (Job 10.22.)
  What is the way to the abode of light? And where does darkness reside? (Job 38.19.)

Light was identified throughout the New Testament with the nature of God, himself.

  The word is light that the darkness cannot extinguish, and this light illuminates every

  man [...] We are the children of light, who have put aside the world of darkness.
