      [T]he Sun of Righteouſneſs [Jesus Christ], when, on the nations of thoſe who are ſaved, he ariſes with healing under his wings, ſhall ſcatter by his brightneſs, every cloud which ſat around them. To the diſtant influence of this powerful luminary on the heart, its regeneration is at preſent owing. But, when every intervening object is removed, and the Chriſtian placed in the light of his countenance, all imperfection flies away.

The author showed the progress of lighthouse luminaries from wood and coal fires to the introduction of tallow candles, fatty oils, mineral oils, coal gas, and electricity.
