This co-operation, then, being necessary, what is the duty which we, as co-workers with God, require to undertake? First of all, and most important of all—the point which we desire particularly to emphasise—we must give ourselves to prayer. “Revivals,” as Dr. J. Wilbur Chapman reminds us, “are born in prayer. When Wesley prayed England was revived; when Knox prayed, Scotland was refreshed; when the Sunday School teachers of Tannybrook prayed, 11,000 young people were added to the Church in a year. Whole nights of prayer have always been succeeded by whole days of soul-winning.”

When D. L. Moody’s Church in Chicago lay in ashes, he went over to England, in 1872, not to preach, but to listen to others preach while his new church was being built. One Sunday morning he was prevailed upon to preach in a London pulpit. But somehow the spiritual atmosphere was lacking. He confessed afterwards that he never had such a hard time preaching in his life. Everything was perfectly dead, and, as he vainly tried to preach, he said to himself, “What a fool I was to consent to preach! I came here to listen, and here I am preaching.” Then the awful thought came to him that he had to preach again at night, and only the fact that he had given the promise to do so kept him faithful to the engagement. But when Mr. Moody entered the pulpit at night, and faced the crowded congregation, he was conscious of a new atmosphere. “The powers of an unseen world seemed to have fallen upon the audience.” As he drew towards the close of his sermon he became emboldened to give out an invitation, and as he concluded he said, “If there is a man or woman here who will to-night accept Jesus Christ, please stand up.” At once about 500 people rose to their feet. Thinking that there must be some mistake, he asked the people to be seated, and then, in order that there might be no possible misunderstanding, he repeated the invitation, couching it in even more definite and difficult terms. Again the same number rose. Still thinking that something must be wrong, Mr. Moody, for the second time, asked the standing men and women to be seated, and then he invited all who really meant to accept Christ to pass into the vestry. Fully 500 people did as requested, and that was the beginning of a revival in that church and neighbourhood, which brought Mr. Moody back from Dublin, a few days later, that he might assist the wonderful work of God.

The sequel, however, must be given, or our purpose in relating the incident will be defeated. When Mr. Moody preached at the morning service there was a woman in the congregation who had an invalid sister. On her return home she told the invalid that the preacher had been a Mr. Moody from Chicago, and on hearing this she turned pale. “What,” she said, “Mr. Moody from Chicago! I read about him some time ago in an American paper, and I have been praying God to send him to London, and to our church. If I had known he was going to preach this morning I would have eaten no breakfast. I would have spent the whole time in prayer. Now, sister, go out of the room, lock the door, send me no dinner; no matter who comes, don’t let them see me. I am going to spend the whole afternoon and evening in prayer.” And so while Mr. Moody stood in the pulpit that had been like an ice-chamber in the morning, the bed-ridden saint was holding him up before God, and God, who ever delights to answer prayer, poured out His Spirit in mighty power.

The God of revivals who answered the prayer of His child for Mr. Moody, is willing to hear and to answer the faithful, believing prayers of His people to-day. Wherever God’s conditions are met there the revival is sure to fall. Professor Thos. Nicholson, of Cornell College, U.S.A., relates an experience on his first circuit that impresses anew the old lesson of the place of prayer in the work of God.

There had not been a revival on that circuit in years, and things were not spiritually hopeful. During more than four weeks the pastor had preached faithfully, visited from house to house, in stores, shops, and out-of-the-way places, and had done everything he could. The fifth Monday night saw many of the official members at lodges, but only a corporal’s guard at the church.

From that meeting the pastor went home, cast down, but not in despair. He resolved to spend that night in prayer. “Locking the door, he took Bible and hymn book and began to inquire more diligently of the Lord, though the meetings had been the subject of hours of earnest prayer. Only God knows the anxiety and the faithful, prayerful study of that night. Near the dawn a great peace and a full assurance came that God would surely bless the plan which had been decided upon, and a text was chosen which he felt sure was of the Lord. Dropping upon the bed, the pastor slept about two hours, then rose, hastily breakfasted, and went nine miles to the far side of the circuit to visit some sick people. All day the assurance increased.

“Toward night a pouring rain set in, the roads were heavy and we reached home, wet, supperless, and a little late, only to find no fire in the church, the lights unlit, and no signs of service. The janitor had concluded that the rain would prevent the service. We changed the order, rang the bell, and prepared for war. Three young men formed the congregation, but in that ‘full assurance’ the pastor delivered the message which had been prayed out on the preceding night, as earnestly and as fully as if the house had been crowded, then made a personal appeal to each young man in turn. Two yielded, and testified before the meeting closed.

“The tired pastor went to a sweet rest, and next morning, rising a little later than usual, learned that one of the young men was going from store to store throughout the town telling of his wonderful deliverance, and exhorting the people to salvation. Night after night conversions occurred, until in two weeks we heard 144 people testify in forty-five minutes. All three points of that circuit saw a blaze of revival that winter, and family after family came into the church, until the membership was more than trebled.

“Out of that meeting one convert is a successful pastor in the Michigan Conference, another is the wife of one of the choicest of our pastors, and a third was in the ministry for a number of years, and then went to another denomination, where he is faithful unto this day. Probably none of the members ever knew of the pastor’s night of prayer, but he verily believes that God somehow does for the man who thus prays, what He does not do for the man who does not pray, and he is certain that ‘more things are wrought by prayer than this world dreams of.’”

All the true revivals have been born in prayer. When God’s people become so concerned about the state of religion that they lie on their faces day and night in earnest supplication, the blessing will be sure to fall.
