The spies were to climb the heights visible in the north, and look forth towards the Great Sea and away to Moriah and Carmel. They were also to make their way cautiously into the land itself and examine it. Moses anticipates that all he has said in praise of Canaan will be made good by the report, and the people will be encouraged to enter at once on the final struggle. When the desert was around them, unfruitful, seemingly interminable, the Israelites might have been disposed to fear that journeying from Egypt they were leaving the fertility of the world farther and farther behind. Some may have thought that the Divine promise had misled and deceived them, and that Canaan was a dream. Even although they had now overpassed that dreary region covered with coarse gravel, black flints, and drifting sand, "the great and terrible wilderness," what hope was there that northward they should reach a land of olives, vineyards, and flowing streams? The report of the spies would answer this question.
Now in like manner the future state of existence may seem dim and unreal, scarcely credible, to many. Our life is like a series of marches hither and thither through the desert. Neither as individuals nor as communities do we seem to approach any state of blessedness and rest. Rather, as years go by, does the region become more inhospitable. Hopes once cherished are one after another disappointed. The stern mountains that overhung the track by which our forefathers went still frown upon us. It seems impossible to get beyond their shadow. And in a kind of despair some may be ready to say: There is no promised land. This waste, with its sere grass, its burning sand, its rugged hills, makes the whole of life. We shall die here in the wilderness like those who have been before us; and when our graves are dug and our bodies laid in them, our existence will have an end. But it is a thoughtless habit to doubt that of which we have no full experience. Here we have but begun to learn the possibilities of life and find a clue to its Divine mysteries. And even as to the Israelites in the wilderness there were not wanting signs that pointed to the fruitful and pleasant country beyond, so for us, even now, there are previsions of the higher world. Some shrubs and straggling vines grew in sheltered hollows among the hills. Here and there a scanty crop of maize was reared, and in the rainy season streams flowed down the wastes. From what was known the Israelites might reason hopefully to that which as yet was beyond their sight. And are there not fore-signs for the soul, springs opened to the seekers after God in the desert, some verdure of righteousness, some strength and peace in believing?
Science and business and the cares of life absorb many and bewilder them. Immersed in the work of their world, men are apt to forget that deeper draughts of life may be drunk than they obtain in the laboratory or the counting-house. But he who knows what love and worship are, who finds in all things the food of religious thought and devotion, makes no such mistake. To him a future in the spiritual world is far more within the range of hopeful anticipation than Canaan was to one who remembered Egypt and had bathed in the waters of the Nile. Is the heavenly future real? It is: as thought and faith and love are real, as the fellowship of souls and the joy of communion with God are realities. Those who are in doubt as to immortality may find the cause of that doubt in their own earthliness. Let them be less occupied with the material, care more for the spiritual possessions, truth, righteousness, religion, and they will begin to feel an end of doubt. Heaven is no fable. Even now we have our foretaste of its refreshing waters and the fruits that are for the healing of the nations.
