God Keeps His Promises -- A Lesson from the Book of Joshua

"And the LORD gave unto Israel all the land which he sware to give unto their fathers; and they possessed it, and dwelt therein. And the LORD gave them rest round about, according to all that he sware unto their fathers: and there stood not a man of all their enemies before them; the LORD delivered all their enemies into their hand. There failed not ought of any good thing which the LORD had spoken unto the house of Israel; all came to pass." --Joshua 21:43-45.

The performance makes the promise appear very true and the promise makes the performance appear very kind.

I. God had promised to give the seed of Abraham the land of Canaan for a possession, and now at last he performed this promise (v. 43): They possessed it, and dwelt therein. Though they had often forfeited the benefit of that promise, and God had long delayed the performance of it, yet at last all difficulties were conquered, and Canaan was their own. And the promise of the heavenly Canaan is as sure to all God's spiritual Israel, for it is the promise of him that cannot lie.

II. God had promised to give them rest in that land, and now they had rest round about, rest from the fatigues of their travel through the wilderness (which tedious march, perhaps, was long in their bones), rest from their wars in Canaan, and the insults which their enemies there had at first offered them. They now dwelt, not only in habitations of their own, but those quiet and peaceable ones; though there were Canaanites that remained, yet none that had either strength or spirit to attack them, nor so much as give them an alarm. This rest continued till they by their own sin and folly put thorns into their own beds and their own eyes.

III. God had promised to give them victory and success in their wars, and this promise likewise was fulfilled: There stood not a man before them, v. 44. They had the better in every battle, and which way soever they turned their forces they prospered. It is true there were Canaanites now remaining in many parts of the land, and such as afterwards made head against them, and became very formidable. But, 1. As to the present remains of the Canaanites, they were no contradiction to the promise, for God had said he would not drive them out all at once, but by little and little, Exod. xxiii. 30. They had now as much in their full possession as they had occasion for and as they had hands to manage, so that the Canaanites only kept possession of some of the less cultivated parts of the country against the beasts of the field, till Israel, in process of time, should become numerous enough to replenish them. 2. As to the after prevalency of the Canaanites, that was purely the effect of Israel's cowardice and slothfulness, and the punishment of their sinful inclination to the idolatries and other abominations of the heathen, whom the Lord would have cast out before them but that they harboured and indulged them. So that the foundation of God stands sure. Israel's experience of God's fidelity is here upon record, and is an acquittance under their hands to the honour of God, the vindication of his promise which had been so often distrusted, and the encouragement of all believers to the end of the world: There failed not any good thing, no, nor aught of any good thing (so full is it expressed), which the Lord had spoken unto the house of Israel, but in due time all came to pass, v. 45. Such an acknowledgment as this, here subscribed by Joshua in the name of all Israel, we afterwards find made by Solomon, and all Israel did in effect say Amen to it, 1 Kings viii. 56. The inviolable truth of God's promise, and the performance of it to the utmost, are what all the saints have been ready to bear their testimony to; and, if in any thing the performance has seemed to come short, they have been as ready to own that they themselves must bear all the blame.
