Whosoever builds his life on the promise of God has in the present the guarantee of the better future. As we are journeying onwards to that great fountain-head of all sweetness and felicity, there are ever trickling brooks from it by the way, at which we may refresh our thirsty lips and invigorate our fainting strength. The present instalment carries with it the pledge of the full discharge of the obligation, and he whose heart and hope is fixed with a forward look on the divine inheritance, may, as he looks backward over all the years, see clearly in them one unbroken mass of preserving providences, and thankfully say, 'The Lord hath kept me alive, as He spake.'

And, still further, the life that is built upon faith like this man's, is a life of buoyant hopefulness till the very end. The hopes of age are few and tremulous. When the feast is nearly over, and the appetite is dulled, there is little more to be done, but to push back our chairs and go away. But God keeps 'the good wine' until the last. And when all earthly hopes are beginning to wear thin and to burn dim, then the great hope of 'the mountain of the inheritance' will rise brighter and clearer upon our horizon. It is something to have a hope so far in front of us that we never get up to it, to find it either less than our expectations or more than our desires; and this is not the least of the blessednesses of the living 'hope that maketh not ashamed,' that it lies before us till the very end, and beckons and draws us across the gulf of darkness. 'The Lord hath kept me alive, as He said; now give me this mountain whereof the Lord spake.'

II. Further, I see here a life that bears to be looked back at.

Caleb becomes almost garrulous in telling over the old story of that never-to-be-forgotten day, when he and Joshua stood alone and tried to put some heart into the cowardly mob before them. There is no mock modesty about the man. He says that, amidst many temptations to be untrue, he gave his report with sincerity and veracity, 'speaking as it was in mine heart,' and then he quotes twice, with a permissible satisfaction, the eulogium that had come upon him from the divine lips, 'I wholly followed the Lord my God.' The private soldier's cheek may well flush and his eye glitter as he repeats over again his general's praise. And for Caleb, half a century has not dimmed the impression that was made on his heart when he received that praise, through the lips of Moses, from God.

Now, of course, such a tone of speaking about one's past savours of an earlier stage in revelation than that in which we live, and, if this were to be taken as a man's total account of his whole life, we could not free it from the charge of unpleasing self-complacency and self-righteousness. But for all that, it is not the same thing in the retrospect whether you and I have to look back upon years that have been given to self, and the world, and passion, and pride, and covetousness, and frivolities and trifles of all sorts, or upon years that in the main, and regard being had to their deepest desires and governing direction, have been given to God and to His service. Many a man looking back upon his life—I wonder if there are any such men listening to me now—can only see such a sight as Abraham did on that morning when he looked down on the plain of Sodom, and 'Lo! the smoke of the land went up as the smoke of a furnace.' Dear friends I the only thing that makes life in the retrospect tolerable is that it shall have been given to God, and that we can say, 'I wholly followed the Lord my God.'

III. Again, I see here a life which has discovered the secret of perpetual youth.

'I,' says the old man—'am as strong this day as I was in the day when Moses sent me. As my strength was then, even so is my strength now, for war, both to go out and to come in.' For fighting, and for all the intercourse and manifold activities of life, his sinews are as braced, his eyes as clear, his spirit and limbs as alert as they were in those old days. No doubt you will say that was due to miraculous intervention. No doubt it was; but is it not true that, in a very real sense, a man may keep himself young all his life, if he will go the right way to work? And the secret of perpetual youthfulness lies here, in giving our hearts to God and in living for Him. Christianity, with its self-restraint and its exhortations to all, and especially to the young, to be chaste and temperate and to subdue the animal passions, has a direct tendency to conserve physical vigour; and Christianity, by the inspiration that it imparts, the stimulus that it gives, and the hopes that it permits us to cherish, has a direct tendency to keep alive in old age all the best of the characteristics of youth. Its buoyancy, its undimmed interest, its cheeriness, its freedom from anxiety and care—all these things are directly ministered to, and preserved by, a life of simple faith that casts itself upon God, and dwells securely, in joy and in restfulness, and not without a great light of hope, even when the shadows of evening are falling.

One of the greatest and most blessed of the characteristics of youth is the consciousness that the most of life lies before us; and to a Christian man, in any stage of his earthly life, that consciousness is possible. When he stands on the verge of the last sinking sandbank of time, and the water is up to his ankles, he may well feel that the best and the most of life is yet to be.

'The last of life, for which the first was made:
Our times are in His hand
Who saith, "A whole I planned.
Youth shows but half; trust God: see all, nor be afraid."'

'They shall still bring forth fruit in old age, they shall be full of sap and green.' A gnarled old tree may be green in all its branches, and blossom and fruit may hang together there. The ideal of life is, that into each stage we shall carry the best of the preceding, harmonised with the best of the new, and that is possible to a Christian soul. The fountain of perpetual youth, of which the ancients fabled, is no fable, but a fact; and it rises, where the prophet in his vision saw the stream coming out, from beneath the threshold of the Temple door.
