Genesis 1:3-4 And God said, Let there be light: and there was light. And God saw the light, that it was good: and God divided the light from the darkness.
2 Corinthians 4:6 For God, who commanded the light to shine out of darkness, hath shined in our hearts, to give the light of the knowledge of the glory of God in the face of Jesus Christ.
Ephesians 5:8 For ye were sometimes darkness, but now are ye light in the Lord: walk as children of light:
1 John 1:5, 7 This then is the message which we have heard of him, and declare unto you, that God is light, and in him is no darkness at all. … But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin.
