Matthew 6:19-22

19. Lay not up for yourselves treasures upon earth, where moth and rust doth corrupt, and where thieves break through and steal:
20. But lay up for yourselves treasures in heaven, where neither moth nor rust doth corrupt, and where thieves do not break through nor steal:
21. For where your treasure is, there will your heart be also.
22. The light of the body is the eye: if therefore thine eye be single, thy whole body shall be full of light.

Matthew 5:14-16

14. Ye are the light of the world. A city that is set on a hill cannot be hid.
15. Neither do men light a candle, and put it under a bushel, but on a candlestick; and it giveth light unto all that are in the house.
16. Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven.

1 Peter 2:9

9. But ye are a chosen generation, a royal priesthood, an holy nation, a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvelous light:

John 1:4-5 & 9-14

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:
13. Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.
14. And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father) full of grace and truth.
