2 Cor 4:6, Jn 1:4-5,9-12, Jn 3:19, Jn 8:12, Jn 12:46
God has given us the light of knowing God, Jesus Christ. (Genesis 1:3, 2 Corinthians 4:6)
Genesis 1:3 And God said, Let there be light: and there was light.
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.
Jesus is the true light of God who came into the world. (John 1:4-5, 9-12, John 3:19, John 8:12, John 12:46)
John 1:4 In him was life; and the life was the light of men. 5 And the light shineth in darkness; and the darkness comprehended it not. 9 That was the true Light, which lighteth every man that cometh into the world. 10 He was in the world, and the world was made by him, and the world knew him not. 11 He came unto his own, and his own received him not. 12 But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name:
John 3:19 And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil.
John 8:12 Then spake Jesus again unto them, saying, I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life.
John 12:46 I am come a light into the world, that whosoever believeth on me should not abide in darkness.
