Matthew 5:14-16 14 Ye are the light of the world. A city that is set on an 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.
Luke 1:78-79 78 Through the tender mercy of our God; whereby the dayspring from on high hath visited us,
79 To give light to them that sit in darkness and in the shadow of death, to guide our feet into the way of peace.
John 3:20-21 20 For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved.
21 But he that doeth truth cometh to the light, that his deeds may be made manifest, that they are wrought in God.
