Our office and work is most honorable, in that we are set by Christ to be lights or luminaries in the spiritual world. Light is the most glorious thing in the material world, and there are, it may be, no parts of the natural world that have so great an image of the goodness of God, as the lights or luminaries of heaven; and especially the sun, who is constantly communicating his benign influence to enlighten, quicken, and refresh the world by his beams; which is probably the reason that the worship of the sun was (as is supposed) the first idolatry that mankind fell into.
