Jesus said: "You are the light of the world." Matt. 5:14. Paul said: "... For Satan himself is transformed into an angel of light."
God said: "I form the light and create darkness: I make peace and create evil: I the Lord do these things." Is. 45:7
And to think in the beginning where all was in darkness, God said: "Let there be light: and there was light." Genesis 1:3 and in Genesis 1:4 "God saw the light and it was good."
Strange, isn't it, that God Himself was no part of bright light. He Himself had to get out of darkness by creating the good light! Poch Suzara
