Charles H. Spurgeon on Psalms 19:6

"His going forth is from the end of the heaven, and his circuit unto the ends of it." He bears his light to the boundaries of the solar heavens, traversing the zodiac with steady motion, denying his light to none who dwell within his range. "And there is nothing hid from the heat thereof." Above, beneath, around, the heat of the sun exercises an influence. The bowels of the earth are stored with the ancient produce of the solar rays, and even yet earth's inmost caverns feel their power. Where light is shut out, yet heat and other more subtle influences find their way.

There is no doubt a parallel intended to be drawn between the heaven of grace and the heaven of nature. God's way of grace is sublime and broad, and full of his glory; in all its displays it is to be admired and studied with diligence; both its lights and its shades are instructive; it has been proclaimed, in a measure, to every people, and in due time shall be yet more completely published to the ends of the earth. Jesus, like a sun, dwells in the midst of revelation, tabernacling among men in all his brightness; rejoicing, as the Bridegroom of his church, to reveal himself to men; and, like a champion, to win unto himself renown. He makes a circuit of mercy, blessing the remotest corners of the earth; and there are no seeking souls, however degraded and depraved, who shall be denied the comfortable warmth and benediction of his love —even death shall feel the power of his presence, and resign the bodies of the saints, and this fallen earth shall be restored to its pristine glory.

In the three following verses (7, 8, 9) we have a brief but instructive hexapla containing six descriptive titles of the word, six characteristic qualities mentioned and six divine effects declared. Names, nature, and effect are well set forth.
