God is resplendently reflected in the souls of His chosen ones, and these pure souls, these images of God, like the transparent glass, shine forth like gold in the sun, like diamonds of the purest water, but they shine for God and the angels, not revealing their brightness to men, although at times, by God's ordering, they do shine even for them, by the light of their faith, their virtues, when necessary, similar to a candle put on a candlestick in a room, and lighting the room with all those who are in it. (cf. Mt. 5:15).
John of Kronstadt
