Is here not (for I do not presume to decide) an allusion to the descent of the Holy Ghost, after the return of Jesus to glory? And may we not without violence to the several expressions here set forth, trace the footsteps of that gracious descent, when, by sending forth his preachers, the arrows of conviction in the sinner's heart are manifested, and the illuminating influence of the Holy Spirit, converting, confirming, and establishing his people in the truth as it is in Jesus, may not unaptly be compared to the lightenings shot forth? Surely, in all instances of the display of grace upon the sinner's heart, in turning them from darkness to light, something similar to the great work the Lord wrought at the Red Sea, is manifested in spirituals, as there in things of nature. The channels of the deeps of sin are seen, and the new and living way, which the Lord opens in the blood and righteousness of Christ for his ransomed to pass over, are no less marvelous, than when the Lord led Israel through the deep, as through a wilderness. Exodus 14:22; Hebrews 10:19-20, etc.

Psalms 18:9-15
9 He bowed the heavens also, and came down: and darkness was under his feet.
10 And he rode upon a cherub, and did fly: yea, he did fly upon the wings of the wind.
11 He made darkness his secret place; his pavilion round about him were dark waters and thick clouds of the skies.
12 At the brightness that was before him his thick clouds passed, hail stones and coals of fire.
13 The LORD also thundered in the heavens, and the Highest gave his voice; hail stones and coals of fire.
14 Yea, he sent out his arrows, and scattered them; and he shot out lightnings, and discomfited them.
15 Then the channels of waters were seen, and the foundations of the world were discovered at thy rebuke, O LORD, at the blast of the breath of thy nostrils.
