Charles H. Spurgeon on Psalms 78:14

In the daytime also he led them with a cloud. HE did it all. He alone. He brought them into the wilderness, and he led them through it; it is not the Lord's manner to begin a work, and then cease from it while it is incomplete. The cloud both led and shadowed the tribes. It was by day a vast sun screen, rendering the fierce heat of the sun and the glare of the desert sand bearable. And all the night with a light of fire. So constant was the care of the Great Shepherd that all night and every night the token of his presence was with his people. That cloud which was a shade by day was as a sun by night. Even thus the grace which cools and calms our joys, soothes and solaces our sorrows. What a mercy to have a light of fire with us amid the lonely horrors of the wilderness of affliction. Our God has been all this to us, and shall we prove unfaithful to him? We have felt him to be both shade and light, according as our changing circumstances have required.

"He hath been our joy in woe,

Cheered our heart when it was low,

And, with warnings softly sad,

Calmed our heart when it was glad."

May this frequently renewed experience knit our hearts to him in firmest bonds.
