Charles H. Spurgeon on Psalms 57:10

For thy mercy is great unto the heavens. Right up from man's lowliness to heaven's loftiness mercy reaches. Imagination fails to guess the height of heaven, and even thus the riches of mercy exceed our highest thoughts. The psalmist, as he sits at the cave's mouth and looks up to the firmament, rejoices that God's goodness is more vast and more sublime than even the vaulted skies. And thy truth unto the clouds. Upon the cloud he sets the seal of his truth, the rainbow, which ratifies his covenant; in the cloud he hides his rain and snow, which prove his truth by bringing to us seedtime and harvest, cold and heat. Creation is great, but the Creator greater far. Heaven cannot contain him; above clouds and stars his goodness far exceeds.
