Charles H. Spurgeon on Psalms 78:16

The supply of water was as plenteous in quantity as it was miraculous in origin. Torrents, not driblets came from the rocks. Streams followed the camp; the supply was not for an hour or a day. This was a marvel of goodness. If we contemplate the abounding of divine grace we shall be lost in admiration. Mighty rivers of love have flowed for us in the wilderness. Alas, great God! our return has not been commensurate therewith, but far otherwise.
