Consequently, when they find the Canaanite still in the land, and see the cities great and walled up to Heaven, they are utterly discouraged, and think they must have gone wrong in some way, and that this cannot be the true land after all. Then, next they make the mistake of looking upon temptation as sin, and of blaming themselves for what in reality is the fault of the enemy only.
Strong temptations are generally a sign of great grace, rather than of little grace.
But afterwards, when they learned better how to trust Him, He permitted their enemies to attack them. Then also in their wilderness journey they met with but few enemies and fought but few battles, compared to those in the land, where they found seven great nations and thirty-one kings to be conquered, besides walled cities to be taken, and giants to be overcome. They could not have fought with the Canaanites, or the Hittites, and the Amorites, and the Perizzites, and the Hivites, and the Jebusites, until they had gone into the land where these enemies were. And the very power of your temptations, dear Christian, therefore, may perhaps be one of the strongest proofs that you really are in the land you have been seeking to enter, because they are temptations peculiar to that land. The second mistake is not quite so easy to deal with.
