Fresh mercies should put us in mind of former mercies. If God bring his people into a wilderness, he will be sure to go before them in it, and to bring them out of it. He provided for them, both in the wilderness and in Canaan.
The daily manna seems here meant. And it looks to the spiritual provision for God's Israel. The Spirit of grace and the gospel of grace are the plentiful rain, with which God confirms his inheritance, and from which their fruit is found.
Christ shall come as showers that water the earth. The account of Israel's victories is to be applied to the victories over death and hell, by the exalted Redeemer, for those that are his. Israel in Egypt among the kilns appeared wretched, but possessed of Canaan, during the reigns of David and Solomon, appeared glorious.
Thus the slaves of Satan, when converted to Christ, when justified and sanctified by him, look honourable. When they reach heaven, all remains of their sinful state disappear, they shall be as the wings of the dove, covered with silver, and her feathers as gold.
Full salvation will render those white as snow, who were vile and loathsome through the guilt and defilement of sin.
