This remarkable writing on the importance of prayer for preachers is by the legendary minister E.M. Bounds. He begins with a quote from Jonathan Edwards:
If some Christians that have been complaining of their ministers had said and acted less before men and had applied themselves with all their might to cry to God for their ministers — had, as it were, risen and stormed heaven with their humble, fervent and incessant prayers for them — they would have been much more in the way of success. — Jonathan Edwards
"SOMEHOW the practice of praying in particular for the preacher has fallen into disuse or become discounted. Occasionally have we heard the practice arraigned as a disparagement of the ministry, being a public declaration by those who do it of the inefficiency of the ministry. It offends the pride of learning and self-sufficiency, perhaps, and these ought to be offended and rebuked in a ministry that is so derelict as to allow them to exist.
Prayer, to the preacher, is not simply the duty of his profession, a privilege, but it is a necessity. Air is not more necessary to the lungs than prayer is to the preacher. It is absolutely necessary for the preacher to pray. It is an absolute necessity that the preacher be prayed for. These two propositions are wedded into a union which ought never to know any divorce: the preacher must pray; the preacher must be prayed for. It will take all the praying he can do, and all the praying he can get done, to meet the fearful responsibilities and gain the largest, truest success in his great work. The true preacher, next to the cultivation of the spirit and fact of prayer in himself, in their intensest form, covets with a great covetousness the prayers of God's people.
The holier a man is, the more does he estimate prayer; the clearer does he see that God gives himself to the praying ones, and that the measure of God's revelation to the soul is the measure of the soul's longing, importunate prayer for God. Salvation never finds its way to a prayerless heart. The Holy Spirit never abides in a prayerless spirit. Preaching never edifies a prayerless soul. Christ knows nothing of prayerless Christians. The gospel cannot be projected by a prayerless preacher. Gifts, talents, education, eloquence, God's call, cannot abate the demand of prayer, but only intensify the necessity for the preacher to pray and to be prayed for. The more the preacher's eyes are opened to the nature, responsibility, and difficulties in his work, the more will he see, and if he be a true preacher the more will he feel, the necessity of prayer; not only the increasing demand to pray himself, but to call on others to help him by their prayers."
