You ought also to consider the end why I have communicated of my light unto you; it is in part the same with that of men: when they light up a candle in a room, which is to show light to all those that are in the room, they do not use to light it up to hide it under a vessel, or a bushel; so I have not communicated my truths or my grace unto you merely for your own use, but for others use. It is said of John, (by our Saviour), he was a burning and shining light: so is every true minister of the gospel, yea, and every true Christian; not only a burning light, burning with love to God, and zeal for God, and love to and zeal for the souls of others; but also a shining light, communicating his light to others, both by instruction and a holy conversation. Others pretended candles were never of God's lighting.
