Disciples are light and should let good works point others to the Father.

Matthew 5:14–16

¹⁴Ye are the light of the world. A city that is set on an hill cannot be hid.

¹⁵Neither 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.

¹⁶Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven.
