Thirdly, the people were instructed,—"Sanctify yourselves, for to-morrow the Lord will do wonders among you." It is an instinct of our nature that when we are to meet with some one of superior worldly rank preparation must be made for the meeting. When Joseph was summoned into the presence of Pharaoh, and they brought him hastily out of the dungeon, "he shaved himself, and changed his raiment, and came in unto Pharaoh." The poorest subject of the realm would try to wear his best and to look his best in the presence of his sovereign. But while "man looketh on the outward appearance the Lord looketh on the heart." And our very instincts teach us, that the heart needs to be prepared when God is drawing near. It is not in our ordinary careless mood that we ought to stand before Him who "sets our iniquities before Him, our secret sins in the light of His countenance." Grant that we can neither atone for our sin, nor cleanse our hearts without His grace; nevertheless, in God's presence everything that is possible ought to be done to remove the abominable thing which He hates, so that He may not be affronted and offended by its presence. Most appropriate, therefore, was Joshua's counsel,—"Sanctify yourselves, for to-morrow the Lord will do wonders among you." He will surpass all that your eyes have seen since that night, much to be remembered, when He divided the sea. He will give you a token of His love and care that will amaze you, much though you have seen of it in the wilderness, and in the country of Sihon and Og. Expect great things, prepare for great things; and let the chief of your preparations be to sanctify yourselves, for "the foolish shall not stand in His sight, and He hateth all workers of iniquity."
Next day (compare ver. 5, "to-morrow," and ver. 7, "this day") Joshua turns to the priests and bids them "take up the ark of the covenant." The priests obey; "they take up the ark, and go before the people."
Shall we take notice of the assertion of some that all those parts of the narrative which refer to priests and religious service were introduced by a writer bent on glorifying the priesthood? Or must we repel the insinuation that the introduction of the ark, and the miraculous effects ascribed to its presence, are mere myths? If they are mere myths, they are certainly myths of a very peculiar kind. Twice only in this book is the ark associated with miraculous events—at the crossing of the Jordan and at the taking of Jericho. If these were myths, why was the myth confined to these two occasions? When mythical writers find a remarkable talisman they introduce it at all sorts of times. Why was the ark not brought to the siege of Ai? Why was it absent from the battles of Bethhoron and Merom? Why was its presence restricted to the Jordan and Jericho, unless it was God's purpose to inspire confidence at first through the visible symbol of His presence, but leave the people afterwards to infer His presence by faith?
The taking up of the ark by the priests was a decisive step. There could be no resiling now from the course entered on. The priests with the ark must advance, and it will be seen whether Joshua has been uttering words without foundation, or whether he has been speaking in the name of God. Shall mere natural forces be brought into play, or shall the supernatural might of heaven come to the conflict, and show that God is faithful to His promise?
Let us put ourselves in Joshua's position. We do not know in what manner the communications were carried on between him and Jehovah of which we have the record under the words "the Lord spake unto Joshua." Was it by an audible voice? Or was it by impressions on Joshua's mind of a kind that could not have originated with himself, but that were plainly the result of Divine influence? In any case, they were such as to convey to Joshua a very clear knowledge of the Divine will. Yet even in the best of men nature is not so thoroughly subdued in such circumstances but that the shadow of anxiety and fear is liable to flit across them. They crave something like a personal pledge that all will go well. Hence the seasonableness of the assurance now given to Joshua—"This day will I begin to magnify thee in the sight of all Israel, that they may know that, as I was with Moses, so I will be with thee." How full and manifold the assurance! First, I will magnify thee. I will endue thee with supernatural might, and that will give you authority and weight, corresponding to the position in which you stand. Further, this shall be but the beginning of a process which will be renewed as often as there is occasion for it. "This day I will begin." You are not to go a warfare on your own charges, but "as your days, so shall your strength be." Moreover, this exaltation of your person and office will take place "in the sight of all Israel," so that no man of them shall ever be justified in refusing you allegiance and obedience. And to sum up—you shall be just as Moses was; the resources of My might will be as available for you as they were for him. After this, what misgivings could Joshua have? Could he doubt the generosity, the kindness, the considerateness of his Master? Here was a promise for life; and no doubt the more he put it to the test in after years the more trustworthy did he find it, and the more convincing was the proof it supplied of the mindfulness of God.
It is an experience which has been often repeated in the case of those who have had to undertake difficult work for their Master. Of all our misapprehensions, the most baseless and the most pernicious is, that God does not care much about us, and that we have not much to look for from Him. It is a misapprehension which dishonours God greatly, and which He is ever showing Himself most desirous to remove. It stands fearfully in the way of that spirit of trust by which God is so much honoured, and which He is ever desirous that we should show. And those who have trusted God, and have gone forward to their work in His strength, have always found delightful evidence that their trust has not been in vain. What is the testimony of our great Christian philanthropists, our most successful missionaries, and other devoted Christian workers? Led to undertake enterprises far beyond their strength, and undergo responsibilities far beyond their means, we know not a single case in which they have not had ample proof of the mindfulness of their Master, and found occasion to wonder at the considerateness and the bountifulness which He has brought to bear upon their position. And is it not strange that we should be so slow to learn how infinite God is in goodness? That we should have no difficulty in believing in the goodness of a parent or of some kind friend who has always been ready to help us in our times of need, but so slow to realize this in regard to God, though we are constantly acknowledging in words that He is the best as well as the greatest of beings? It is a happy era in one's spiritual history when one escapes from one's contracted views of the love and liberality of God, and begins to realize that "as far as heaven is above the earth, so far are His ways above our ways, and His thoughts above our thoughts"; and when one comes to find that in one's times of need, whether arising from one's personal condition or from the requirements of public service, one may go to God for encouragement and help with more certainty of being well received than one may go to the best and kindest of friends.
It is sometimes said that the Old Testament presents us with a somewhat limited view of God's love. Certainly it is in the New Testament that we see it placed in the brightest of all lights—the Cross, and that we find the argument in its most irresistible form—"He that spared not His own Son, but delivered Him up for us all, how shall He not, with Him also, freely give us all things?" But one must have read the Old Testament in a very careless spirit if one has not been struck with its frequent and most impressive revelations of God's goodness. What scenes of gracious intercourse with His servants does it not present from first to last, what outpourings of affection, what yearnings of a father's heart! If there were many in Old Testament times whom these revelations left as heedless as they found them, there were certainly some whom they filled with wonder and roused to words of glowing gratitude. The Bible is not wont to repeat the same thought in the same words. But there is one truth and one only which we find repeated again and again in the Old Testament, in the same words, as if the writers were never weary of them—"For His mercy endureth for ever." Not only is it the refrain of a whole psalm (cxxxvi.), but we find it at the beginning of three other psalms (cvi., cvii., cxviii.), we find it in David's song of dedication when the ark was brought up to Jerusalem (1 Chron. xvi. 34), and we find also that on the same occasion a body of men, Heman and Jeduthun and others, were told off expressly "to give thanks to the Lord, because His mercy endureth for ever" (1 Chron. xvi. 41). This, indeed, is the great truth which gives the Old Testament its highest interest and beauty. In the New Testament, in its evangelical setting, it shines with incomparable brightness. Vividly realized, it makes the Christian's cup to flow over; as it fills him likewise with the hope of a joy to come—"a joy unspeakable and full of glory."
