Further, my text suggests that for those who follow the Lamb there shall be greenness and pasture on the bare heights. Strip that part of our text of its metaphor, and it just comes to the blessed old thought, which I hope many of us have known to be a true one, that the times of sorrow are the times when a Christian may have the most of the presence and strength of God. 'In the days of famine they shall be satisfied,' and up among the most barren cliffs, where there is not a bite for any four-footed creature, they shall find springing grass and watered pastures. Our prophet puts the same thought, under a kindred though somewhat different metaphor, in another place in this book, where he says, 'I will open rivers in high places.' That is clean contrary to nature. The rivers do not run on the mountain-tops, but down in the low ground. But for us, as the darkness thickens, the pillar may glow the brighter; as the gloom increases, the glory may grow; the less of nutriment or refreshment earth affords, the more abundantly does God spread His stores before us, if we are wise enough to take them. It is an experience, I suppose, common to all devout men, that their times of most rapid growth were their times of trouble. In nature winter stops all vegetable life. In grace the growing time is the winter. They tell us that up in the Arctic regions the reindeer will scratch away the snow, and get at the succulent moss that lies beneath it. When that Shepherd, Who Himself has known sorrows, leads us up into those barren regions of perpetual cold and snow, He teaches us, too, how to brush it away, and find what we need buried and kept safe and warm beneath the white shroud. It is the prerogative of the Christian soul not to be without trouble, but to turn the trouble into nourishment, and to feed on the barest heights. May I turn these latter words of our text a somewhat different way, attaching to them a meaning which does not belong to them, but by way of accommodation? If Christian people want to have the bread of God abundantly, they must climb. It is to those who live on the heights that provision comes according to their need. If you would have your Christian life starved, go down into the fertile valleys. Remember Abraham and Lot, and the choice which each made. The one said: 'I want cattle and wealth, and I am going down to Sodom. Never mind about the vices of the inhabitants. There is money to be made there.' Abraham said: 'I am going to stay up here on the heights, the breezy, barren heights,' and God stayed beside him. If we go down we starve our souls. If we desire them to be fat and flourishing, nourished with the hidden manna, then we must go up. 'Their pasture shall be in all high places.'
