This, however, is but one half the lesson of the siege of Jericho. The other and not less valuable lesson is, that in many good enterprises, all that is done may appear for a long time to be labour lost, and not to advance us by one step nearer to the object in view. For six days the priests carried the ark round Jericho, but not one stone was loosened from the walls, not by one iota did the defences seem to yield. Six times on the seventh day there was an equally complete want of result. Nay, the seventh perambulation on the seventh day appeared to be equally unsuccessful, until the very last moment; but when that moment came, the whole defences of the city came tumbling to the ground. It is often God's method to do a great deal of work unseen, and then on a sudden effect the consummation. And whenever we are working in accordance with God's will, it is our encouragement to believe that though our visible success is hardly appreciable, yet good and real work is done. For one day is with the Lord as a thousand years, and a thousand years as one day. Sometimes in a thousand years God does not seem to accomplish a good day's work, but at other times in a single day He does the work of a thousand years. The reformation of the Church in the Middle Ages,--how little progress it seemed to make during weary centuries; and even when victory seemed to be drawing nigh, how thoroughly was it arrested by the martyrdom of Huss and Jerome in Bohemia, the extinction of the light of Wicliffe in England, and the suppression of the Lollards in Scotland! And when in Providence some causes began to operate that seemed to have a bearing on the desired consummation, such as the invention of printing, the revival of learning, and the love of freedom, how feebly they seemed to operate in opposition to that overwhelming force which the Papacy had been accumulating for centuries, and which nothing seemed able to touch! But when Luther appeared, nailed his theses to the door of the church at Wittemberg, and took up the bold attitude of an out-and-out opponent to Rome, in one hour the Church was struck as with an earthquake; it reeled to its foundations, and half of the proud structure fell. The conflict with American slavery, how slowly it advanced for many a year, nay, at times it seemed to be even losing ground; till in the midst of the great Civil War the President signed a certain proclamation, and in one moment American slavery received its death blow. An eminent historian of England has a striking picture of the slow, steady, awful triumph of iniquity in the career of Cardinal Wolsey, and the sudden collapse of the structure built up so carefully by that wicked man. Speaking of the final retribution, he says: "The time of reckoning at length was arrived. Slowly the hand had crawled along the dial plate, slowly as if the event would never come, and wrong was heaped on wrong, and oppression cried, and it
