A VESSEL in full sail scuds merrily over the waves. Everything betokens a successful and delightful voyage. The log has just been taken, marking an extraordinary run. The passengers are in the highest spirits, anticipating an early close of the voyage. Suddenly a shock is felt, and terror is seen on every face. The ship has struck on a rock. Not only is progress arrested, but it will be a mercy for crew and passengers if they can escape with their lives.

Not often so violently, but often as really, progress is arrested in many a good enterprise that seemed to be prospering to a wish. There may be no shock, but there is a stoppage of movement. The vital force that seemed to be carrying it on towards the desired consummation declines, and the work hangs fire. A mission that in its first stages was working out a beautiful transformation, becomes languid and advances no further. A Church, eminent for its zeal and spirituality, comes down to the ordinary level, and seems to lose its power. A family that promised well in infancy and childhood fails of its promise, its sons and daughters waver and fall. A similar result is often found in the undertakings of common life. Something mysterious arrests progress in business or causes a decline. In "enterprises of great pith and moment," "the currents turn awry, and lose the name of action."

In all such cases we naturally wonder what can be the cause. And very often our explanation is wide of the mark. In religious enterprises, we are apt to fall back on the sovereignty and inscrutability of God. "He moves in a mysterious way, His wonders to perform." It seems good to Him, for unknown purposes of His own, to subject us to disappointment and trial. We do not impugn either His wisdom or His goodness; all is for the best. But, for the most part, we fail to detect the real reason. That the fault should lie with ourselves is the last thing we think of. We search for it in every direction rather than at home. We are ingenious in devising far-off theories and explanations, while the real offender is close at hand - "Israel hath sinned."

It was an unexpected obstacle of this kind that Joshua now encountered in his next step towards possessing the land. Let us endeavour to understand his position and his plan. Jericho lay in the valley of the Jordan, and its destruction secured nothing for Joshua save the possession of that low-lying valley. From the west side of the valley rose a high mountain wall, which had to be ascended in order to reach the plateau of Western Palestine. Various ravines or passes ran down from the plateau into the valley; at the top of one of these, a little to the north of Jericho, was Bethel, and farther down the pass, nearer the plain, the town or village of Ai. No remains of Ai are now visible, nor is there any tradition of the name, so that its exact position cannot be ascertained. It was an insignificant place, but necessary to be taken, in order to give Joshua command of the pass, and enable him to reach the plateau above. The plan of Joshua seems to have been to gain command of the plateau about this point, and thereby, as it were, cut the country in two, so that he might be able to deal in succession with its southern and its northern sections. If once he could establish himself in the very centre of the country, keeping his communications open with the Jordan valley, he would be able to deal with his opponents in detail, and thus prevent those in the one section from coming to the assistance of the other. Neither Ai nor Bethel seemed likely to give him trouble; they were but insignificant places, and a very small force would be sufficient to deal with them.

Hitherto Joshua had been eminently successful, and his people too. Not a hitch had occurred in all the arrangements. The capture of Jericho had been an unqualified triumph. It seemed as if the people of Ai could hardly fail to be paralysed by its fate. After reconnoitring Ai, Joshua saw that there was no need for mustering the whole host against so poor a place - a detachment of two or three thousand would be enough. The three thousand went up against it as confidently as if success were already in their hands. It was probably a surprise to find its people making any attempt to drive them off. The men of Israel were not prepared for a vigorous onslaught, and when it came thus unexpectedly they were taken aback and fled in confusion. As the men of Ai pursued them down the pass, they had no power to rally or retrieve the battle; the rout was complete, some of the men were killed, while consternation was carried into the host, and their whole enterprise seemed doomed to failure.

And now for the first time Joshua appears in a somewhat humiliating light. He is not one of the men that never make a blunder. He rends his clothes, falls on his face with the elders before the ark of the Lord till even, and puts dust upon his head. There is something too abject in this prostration. And when he speaks to God, it is in the tone of complaint and in the language of unbelief. ''Alas, O Lord God, wherefore hast Thou at all brought this people over Jordan, to deliver us into the hand of the Amorites, to destroy us? would to God we had been content, and dwelt on the other side Jordan! O Lord, what shall I say, when Israel turneth their backs before their enemies! For the Canaanites and all the inhabitants of the land shall hear of it, and shall environ us round, and cut off our name from the earth: and what wilt Thou do unto Thy great name?" Thus Joshua almost throws the blame on God. He seems to have no idea that it may lie in quite another quarter. And very strangely, he adopts the very tone and almost the language of the ten spies, against which he had protested so vehemently at the time: "Would God that we had died in the land of Egypt, or would God we had died in this wilderness! And wherefore hath the Lord brought us unto this land, to fall by the sword, that our wives and our children should be a prey?" What has become of all your courage, Joshua, on that memorable day? Is this the man to whom God said so lately, "Be strong, and of good courage; as I was with Moses, so I will be with thee. I will not fail thee nor forsake thee"? Like Peter on the waters, and like so many of ourselves, he begins to sink when the wind is contrary, and his cry is the querulous wail of a frightened child! After all he is but flesh and blood.

Now it is God's turn to speak. "Get thee up; wherefore liest thou thus upon thy face?" Why do you turn on Me as if I had suddenly changed, and become forgetful of My promise? Alas, my friends, how often is God slandered by our complaints! How often do we feel and even speak as if He had broken His word and forgotten His promise, as if He had induced us to trust in Him, and accept His service, only to humiliate us before the world, and forsake us in some great crisis! No wonder if God speak sharply to Joshua, and to us if we go in Joshua's steps. No wonder if He refuse to be pleased with our prostration, our wringing of our hands and sobbing, and calls us to change our attitude. ''Get thee up; wherefore liest thou thus upon thy face?"

Then comes the true explanation - "Israel hath sinned." Might you not have divined that this was the real cause of your trouble? Is not sin directly or indirectly the cause of all trouble? What was it that broke up the joy and peace of Paradise? Sin. What brought the flood of waters over the face of the earth to destroy it? Sin. What caused the confusion of Babel and scattered the inhabitants over the earth in hostile races? Sin. What brought desolation on that very plain of Jordan, and buried its cities and its people under an avalanche of fire and brimstone? Sin. What caused the defeat of Israel at Hormah forty years ago, and doomed all the generation to perish in the wilderness? Sin. What threw down the walls of Jericho only a few days ago, gave its people to the sword of Israel, and reduced its homes and its bulwarks to the mass of ruins you see there? Again, sin. Can you not read the plainest lesson? Can you not divine that this trouble which has come on you is due to the same cause with all the rest? And if it be a first principle of Providence that all trouble is due to sin, would it not be more suitable that you and your elders should now be making diligent search for it, and trying to get it removed, than that you should be lying on your faces and howling to me, as if some sudden caprice or unworthy humour of mine had brought this distress upon you?

''Behold, the Lord's ear is not heavy that it cannot hear, nor His arm shortened that it cannot save. But your iniquities have separated between you and your God." What a curse that sin is, in ways and forms, too, which we do not suspect! And yet we are usually so very careless about it. How little pains we take to ascertain its presence, or to drive it away from among us! How little tenderness of conscience we show, how little burning desire to be kept from the accursed thing! And when we turn to our opponents and see sin in them, instead of being grieved, we fall on them savagely to upbraid them, and we hold them up to open scorn. How little we think if they are guilty, that their sin has intercepted the favour of God, and involved not them only, but probably the whole community in trouble! How unsatisfactory to God must seem the bearing even of the best of us in reference to sin! Do we really think of it as the object of God's abhorrence? As that which destroyed Paradise, as that which has covered the earth with lamentation and mourning and woe, kindled the flames of hell, and brought the Son of God to suffer on the cross? If only we had some adequate sense of sin, should we not be constantly making it our prayer - ''Search me, O God, and know my heart; try me, and know my thoughts; and see if there be any wicked way in me, and lead me in the way everlasting"?

The peculiar covenant relation in which Israel stood to God caused a method to be fallen on for detecting their sin that is not available for us. The whole people were to be assembled next morning, and inquiry was to be made for the delinquent in God's way, and when the individual was found condign punishment was to be inflicted. First the tribe was to be ascertained, then the family, then the man. For this is God's way of tracking sin. It might be more pleasant to us that He should deal with it more generally, and having ascertained, for example, that the wrong had been done by a particular tribe or community, inflict a fine or other penalty on that tribe in which we should willingly bear our share. For it does not grieve us very much to sin when every one sins along with us. Nay, we can even make merry over the fact that we are all sinners together, all in the same condemnation, in the same disgrace. But it is a different thing when we are dealt with one by one. The tribe is taken, the family is taken, but that is not all; the household that God shall take shall come man by man! It is that individualizing of us that we dread; it is when it comes to that, that "conscience makes cowards of us all." When a sinner is dying, he becomes aware that this individualizing process is about to take place, and hence the fear which he often feels. He is no longer among the multitude, death is putting him by himself, and God is coming to deal with him by himself. If he could only be hid in the crowd it would not matter, but that searching eye of God - who can stand before it? What will all the excuses or disguises or glosses he can devise avail before Him who "sets our iniquities before Him, our secret sins in the light of His countenance"? "Neither is there any creature that is not manifest in His sight; for all things are naked, and opened unto the eyes of Him with whom we have to do." Happy, in that hour, they who have found the Divine covering for sin: ''Blessed is he whose transgression is forgiven, whose sin is covered. Blessed is the man to whom the Lord imputeth not iniquity, and in whose spirit there is no guile."

But before passing on to the result of the scrutiny, we find ourselves face to face with a difficult question. If, as is here intimated, it was one man that sinned, why should the whole nation have been dealt with as guilty? Why should the historian, in the very first verse of this Chapter, summarise the transaction by saying: "But the children of Israel committed a trespass in the devoted thing: for Achan, the son of Carmi, the son of Zabdi, the son of Zevsihy of the tribe of Judah, took of the devoted thing; and the anger of the Lord was kindled against the children of Israel"? Why visit the offence of Achan on the whole congregation, causing a peculiarly humiliating defeat to take place before an insignificant enemy, demoralizing the whole host, driving Joshua to distraction, and causing the death of six-and-thirty men?

In dealing with a question of this sort, it is indispensable that we station ourselves at that period of the world's history; we must place before our minds some of the ideas that were prevalent at the time, and abstain from judging of what was done then by a standard which is applicable only to our own day.

And certain it is that, what we now call the solidarity of mankind, the tendency to look on men rather as the members of a community than as independent individuals, each with an inalienable standing of his own, had a hold of men's minds then such as it has not to-day, certainly among Western nations. To a certain extent, this principle of solidarity is inwoven in the very nature of things, and cannot be eliminated, however we may try. Absolute independence and isolation of individuals are impossible. In families, we suffer for one another's faults, even when we hold them in abhorrence. We benefit by one another's virtues, though we may have done our utmost to discourage and destroy them. In the Divine procedure toward us, the principle of our being a corporate body is often acted upon. The covenant of Adam was founded on it, and the fall of our first parents involved the fall of all their descendants. In the earlier stages of the Hebrew economy, wide scope was given to the principle. It operated in two forms: sometimes the individual suffered for the community, and sometimes the community for the individual. And the operation of the principle was not confined to the Hebrew or to other Oriental communities. Even among the Romans it had a great influence. Admirable though Roman law was in its regulation of property, it was very defective in its dealings with persons. ''Its great blot was the domestic code. The son was the property of the father, without rights, without substantial being, in the eye of Roman law. . . . The wife again was the property of her husband, an ownership of which the moral result was most disastrous."*

*See Mozley's "Ruling Ideas in the Early Ages," p. 40.

We are to remember that practically the principle of solidarity was fully admitted in Joshua's time among his people. The sense of injustice and hardship to which it might give rise among us did not exist. Men recognised it as a law of wide influence in human affairs, to which they were bound to defer.

Hence it was that when it became known that one man's offence lay at the foundation of the defeat before Ai, and of the displeasure of God toward the people at large, there was no outcry, no remonstrance, no complaint of injustice. This could hardly take place if the same thing were to happen now. It is hard to reconcile the transaction with our sense of justice. And no doubt, if we view the matter apart and by itself, there may be some ground for this feeling. But the transaction will assume another aspect if we view it as but a part of a great whole, of a great scheme of instruction and discipline which God was developing in connection with Israel. In this light, instead of a hardship it will appear that in the end a very great benefit was conferred on the people.

Let us think of Achan's temptation. A large amount of valuable property fell into the hands of the Israelites at Jericho. By a rigorous law, all was devoted to the service of God. Now a covetous man like Achan might find many plausible reasons for evading this law. "What I take to myself (he might say) will never be missed. There are hundreds of Babylonish garments, there are many wedges of gold, and silver shekels without number, amply sufficient for the purpose for which they are devoted. If I were to deprive another man of his rightful share, I should be acting very wickedly; but I am really doing nothing of the kind. I am only diminishing imperceptibly what is to be used for a public purpose. Nobody will suffer a whit by what I do, - it cannot be very wrong."

Now the great lesson taught very solemnly and impressively to the whole nation was, that this was just awfully wrong. The moral benefit which the nation ultimately got from the transaction was, that this kind of sophistry, this flattering unction which leads so many persons ultimately to destruction, was exploded and blown to shivers. A most false mode of measuring the criminality of sin was stamped with deserved reprobation. Every man and woman in the nation got a solemn warning against a common but ruinous temptation. In so far as they laid to heart this warning during the rest of the campaign, they were saved from disastrous evil, and thus, in the long run, they profited by the case of Achan.

That sin is to be held sinful only when it hurts your fellow-creatures, and especially the poor among your fellow-creatures, is a very common impression, but surely it is a delusion of the devil. That it has such effects may be a gross aggravation of the wickedness, but it is not the heart and core of it. And how can you know that it will not hurt others? Not hurt your fellowcountrymen, Achan? Why, that secret sin of yours has caused the death of thirty-six men, and a humiliating defeat of the troops before Ai. More than that, it has separated between the nation and God. Many say, when they tell a lie, it was not a malignant lie, it was a lie told to screen some one, not to expose him, therefore it was harmless. But you cannot trace the consequences of that lie, any more than Achan could trace the consequences of his theft, otherwise you would not dare to make that excuse. Many that would not steal from a poor man, or waste a poor man's substance, have little scruple in wasting a rich man's substance, or in peculating from Government property. Who can measure the evil that flows from such ways of trifling with the inexorable law of right, the damage done to conscience, and the guilt contracted before God? Is there safety for man or woman except in the most rigid regard to right and truth, even in the smallest portions of them with which they have to do? Is there not something utterly fearful in the propagating power of sin, and in its way of involving others, who are perfectly innocent, in its awful doom? Happy they who from their earliest years have had a salutary dread of it, and of its infinite ramifications of misery and woe!

How well fitted for us, especially when we are exposed to temptation, is that prayer of the psalmist: "Who can understand his errors? cleanse Thou me from secret faults. Keep back Thy servant also from presumptuous sins; let them not have dominion over me: then shall I be perfect, and I shall be clear of great transgression."
