"And all the congregation of the children of Israel journeyed from the wilderness of Sin, after their journeys, according to the commandment of the Lord, and pitched in Rephidim: and there was no water for the people to drink. Wherefore the people did chide with Moses, and said, 'Give us water that we may drink.' And Moses said unto them, 'Why chide ye with me? Wherefore do ye tempt the Lord?'" (Chap. xvii. 1, 2.) Did we not know something of the humiliating evil of our own hearts, we should be quite at a loss to account for Israel's marvelous insensibility to all the Lord's goodness, faithfulness, and mighty acts. They had just seen bread descending from heaven to feed six hundred thousand people in the wilderness; and now they are "ready to stone" Moses for bringing them out into the wilderness to kill them with thirst. Nothing can exceed the desperate unbelief and wickedness of the human heart save the superabounding grace of God. In that grace alone can any one find relief under the growing sense of his evil nature which circumstances tend to make manifest. Had Israel been transported directly from Egypt to Canaan, they would not have made such sad exhibitions of what the human heart is, and, as a consequence, they would not have proved such admirable ensamples or types for us; but their forty years' wandering in the desert furnishes us with a volume of warning, admonition, and instruction, fruitful beyond conception. From it we learn, amongst many other things, the unvarying tendency of the heart to distrust God. Any thing, in short, for it but God. It would rather lean upon a cobweb of human resources than upon the arm of an omnipotent, all-wise, and infinitely gracious God; and the smallest cloud is more than sufficient to hide from its view the light of His blessed countenance. Well, therefore, may it be termed "an evil heart of unbelief," which will ever show itself ready to "depart from the living God."
