And these precious promises are confirmed by striking examples, in every age of the church. Thus, Abraham prayed for Sodom; and, through his intercession, Lot was saved. His servant, when sent to obtain a wife for Isaac, received a direct answer to prayer. When Jacob heard that his brother Esau was coming against him, with an army of four hundred men, he wrestled all night in prayer, and prevailed; so that Esau became reconciled to him. Moses prayed for the plagues to come upon Egypt, and they came; again, he prayed for them to be removed, and they were removed. It was through his prayers that the Red Sea was divided, the manna and the quails were sent, and the waters gushed out of the rock And through his prayers, many times, the arm of the Lord was stayed, which had been uplifted to destroy his rebellious people. Samuel, that lovely example of early piety, and the judge and deliverer of Israel, was given in answer to the prayer of his mother. When the children of Israel were in danger of being overthrown by the Philistines, Samuel prayed, and God sent thunder and lightning, and destroyed the armies of their enemies. Again, to show their rebellion against God, in asking a king, he prayed, and God sent thunder and lightning upon them in the time of wheat harvest. In order to punish the idolatry and rebellion of the Israelites, Elijah prayed earnestly that it might not rain; and it rained not for three years and six months. Again; he prayed that it might rain, and there arose a little cloud, as a man's hand, which spread and covered the heavens with blackness, till the rain descended in torrents. Again; when wicked Ahab sent a band of men to take him, he prayed, and fire came down from heaven, and consumed them. Hezekiah, upon the bed of death, prayed, and God lengthened his life fifteen years. Jerusalem was invaded by the army of Sennacherib, and threatened with destruction. Hezekiah prayed, and the angel of the Lord entered the camp of the invader, and in one night slew one hundred and eighty-five thousand men. When all the wise men of Babylon were threatened with destruction, because they could not discover Nebuchadnezzar's dream, Daniel and his companions prayed, and the dream and its explanation were revealed. Jonah prayed, and was delivered from the power of the fish. It was in answer to the prayer of Zacharias, that the angel Gabriel was sent to inform him of the birth of John the Baptist. It was after a ten days' prayer-meeting, that the Holy Ghost came down, on the day of Pentecost, "like a mighty rushing wind." Again; while the disciples were praying, the place was shaken where they were assembled, to show that God heard their prayers. It was in answer to the prayers of Cornelius, that Peter was sent to teach him the way of life. When Peter was imprisoned by Herod, the church set apart the night before his expected execution, for special prayer in his behalf. The Lord sent his angel, opened the prison doors, and restored him to the agonizing band of brethren. And when Paul and Silas were thrown into the dungeon, with their feet fast in the stocks, they prayed, and there was a great earthquake, which shook the foundations of the prison, so that all the doors were opened.

But the faithfulness of God to his promises is not confined to Scripture times. Although the time of miracles has passed, yet every age of the church has furnished examples of the faithfulness of God in hearing the prayers of his children. But these are so numerous that it is difficult to make selections from them. However, I will mention a few. When the Arians, who denied the divinity of Christ, were about to triumph, the Bishop of Constantinople, and one of his ministers, spent a whole night in prayer. The next day, Arius, the leader of his party, was suddenly cut off, by a violent and distressing disease. This prevented the threatened danger. Augustine was a wild youth, sunk in vice, and a violent opposer of religion. His mother persevered in prayer for him nine years, when he was converted, and became the most eminent minister of his age. The life of Francke exhibits the most striking and signal answers to prayer. His orphan house was literally built up and sustained by prayer. If you have not already read this work, I would advise you to obtain it. It is a great help to weak faith. Mr. West (afterwards Dr. West) became pastor of the Congregational church in Stockbridge, Massachusetts, while destitute of vital piety. Two pious females often lamented to each other that they got no spiritual food from his preaching. At length, they agreed to meet once a week, to pray for his conversion. They continued this for some time, under much discouragement. But, although the Lord tried their faith, yet he never suffered them both to be discouraged at the same time. At length, their prayers were heard. There was a sudden and remarkable change in his preaching. "What is this?" said one of them. "God is the hearer of prayer," replied the other. The Spirit of God had led Mr. West to see that he was a blind leader of the blind. He was converted, and changed his cold morality for the cross of Christ, as the basis of his sermons. A pious slave in Newport, Rhode Island, was allowed by his master to labor for his own profit whatever time he could gain by extra diligence. He laid up all the money he earned in this way, for the purpose of purchasing the freedom of himself and family. But, when some of his Christian friends heard what he was doing, they advised him to spend his gained time in fasting and prayer. Accordingly, the next day that he gained, he set apart for this purpose. Before the close of the day, his master sent for him, and gave him a written certificate of his freedom. This slave's name was Newport Gardner. He was a man of ardent piety; and in 1825, he was ordained deacon of a church of colored people, who went out from Boston to Liberia. Instances of surprising answers to prayer, no less striking than these, are continually occurring in the revivals of religion of the present day.

With the evidence here presented, who can doubt that God hears and answers prayer? But, the objection arises, "If this doctrine be really true, why is it that Christians offer up so many prayers without receiving answers?" The apostle James gives some explanation of this difficulty: "Ye ask and receive not, because ye ask amiss." It becomes us, then, seriously and diligently to inquire how we may ask aright so as to secure the blessings so largely promised in answer to prayer. In relation to this subject, there are several things to be observed:

1. We must sincerely desire the things which we ask. If a child should ask his mother for a piece of bread, when she knew he was not hungry, but was only trifling with her, it would not he proper for her to give it. Indeed, she would have just cause to punish him for mocking her. And do we not often come to the throne of grace, when we do not really feel our perishing need of the things we ask? God sees our hearts; and he is not only just in withholding the blessing we ask, but in chastising us for solemn trifling.

2. We must desire what we ask, that God may be glorified. "Ye ask amiss, that ye may consume it upon your lusts." We may possibly ask spiritual blessings for self-gratification; and when we do so, we have no reason to expect that God will bestow them upon us.

3. We must ask for things agreeable to the will of God. "And this is the confidence that we have in him, that if we ask anything according to his will, he heareth us." The things that we ask must be such, in kind, as he has indicated his willingness to bestow upon us. Such are, spiritual blessings on our own souls; the supply of our necessary temporal wants; and the extension of his kingdom. These are the kind of blessings that we are to ask; and the degree of confidence with which we are to look for an answer must be in proportion to the positiveness of the promises. Our Lord assures us that our heavenly Father is more willing to give good things, and particularly his Holy Spirit, to them that ask him, than earthly parents are to give good gifts to their children; and he declares expressly, that our sanctification is agreeable to the will of God. The promises of the daily supply of our necessary temporal wants are equally positive. What, then, can be more odious in the sight of God, than for those who profess to be his children to excuse their want of spirituality on the ground of their dependence upon him? And what more ungrateful, than to fret and worry themselves, lest they should come to want? We may also pray for a revival of religion in a particular place, and for the conversion of particular individuals, with strong ground of confidence, because we know that God has willed the extension of Christ's kingdom, and that the conversion of sinners is, in itself, agreeable to his will. But we cannot certainly know that he intends to convert a particular individual, or revive his work in a particular place; nor can we be sure that the particular temporal blessing that we desire is what the Lord sees to be needful for our present necessities.

4. We must ask in faith. "But let him ask in faith, nothing wavering. For he that wavereth is like a wave of the sea, driven with the winds, and tossed. For let not that man think that he shall receive anything of the Lord." A difference of opinion exists among real Christians, as to what constitutes the prayer of faith spoken of by the apostle. Some maintain that we must believe that we shall receive the very thing for which we ask. This opinion is founded on some promises made by our Lord to the apostles, which those who hold the contrary opinion suppose to have been intended only for them. I shall not attempt to determine this point; nor do I think it very important which of these theories is embraced; because, in examining the history of those persons whose prayers have received the seal of heaven, I find some of them embraced one, and some the other; while many who embrace either of them seem not to live in the exercise of prevailing prayer. The main point, therefore, seems to be, that we should maintain such a nearness of communion with God as shall secure the personal exercise of the prayer of faith. Two things, however, are essential to this: (1.) Strong confidence in the existence and faithfulness of God. "He that cometh unto God must believe that he is, and that he is a rewarder of them that diligently seek him." (2.) The prayer of faith must be dictated by the Holy Spirit. Faith itself is declared to be "the gift of God;" and the apostle says, "The Spirit also helpeth our infirmities; for we know not what we should pray for as we ought, but the Spirit itself maketh intercession for us, with groanings which cannot be uttered." "He maketh intercession for the saints, according to the will of God." When this wonderful truth is made known, we are no longer astonished that God should assure us, by so many precious promises, that he will hear and answer our prayers. We are called the temples of the Holy Ghost. If the Holy Ghost dwell in us, to guide and direct us in all our ways, will he forsake us in so important a matter as prayer? O, then, what a solemn place is the Christian's closet, or the house of prayer! There the whole Trinity meet in awful concert. The Holy Spirit there presents to the everlasting Father, through the eternal Son, the prayers of a mortal worm! Is it any wonder that such a prayer should be heard? With what holy reverence and godly fear should we approach this consecrated place!

5. We must ask in a spirit of humble submission, yielding our wills to the will of the Lord, committing the whole case to him, in the true spirit of our Lord's agonizing prayer in the garden, when he said, "Not my will but thine be done." If I had a house full of gold, and had promised to give you as much as you desire, would you need to be urged to ask? But, there is an inexhaustible fulness of spiritual blessings treasured up in Christ; and he has declared repeatedly that you may have as much as you will ask. Need you be urged to ask? Need you want any grace? It is unbelief that keeps us so far from God. From what has been said on this subject, I think you may safely conclude that your progress in the divine life will be in proportion to the real prayer of faith which you exercise.

But I come now to give a few practical directions respecting the exercise of prayer. Several things are necessary to be observed by every one who would live near the throne of grace.

1. Maintain a constant spirit of prayer. "Pray without ceasing." "Continuing instant in prayer." "Praying always, with all prayer and supplication in the Spirit." "And he spake a parable unto them, to this end, that men ought always to pray, and not to faint." The meaning of these passages is not that we should be always upon our knees, but that we should maintain such a prayerful frame, that the moment our minds are disengaged, our hearts will rise up to God. Intimately connected with this is the practice of ejaculatory prayer, which consists of a short petition, silently and suddenly sent up from the heart. This may be done anywhere, and under all circumstances. Frequent examples of this kind of prayer are recorded in Scripture. It has also been the practice of living Christians in all ages. It is a great assistance in the Christian warfare. It helps us in resisting temptation; and by means of it, we can seek divine aid in the midst of the greatest emergencies. To maintain this unceasing spirit of prayer is a very difficult work. It requires unwearied care and watchfulness, labor, and perseverance. Yet no Christian can thrive without it.
