Never account prayer second to preaching. No doubt prayer in the Christian church is as precious as the utterance of the gospel. To speak to God for men is a part of the Christian priesthood that should never be despised. Surely I have heard some prayers of those whom none would ever have expected to pray, such as I have not heard from those who, from their youth up, have been accustomed to the language of devotion — moved with energy and full of fervor, like Elijah. Or, shall I say it, they have become in spiritual force nerved as Samson was with physical strength. In their prayers they have seemed to take hold of the pillars of the temple of Satan, and pull it down upon their enemies; they have been so mighty as to wrestle with God and prevail.
From a sermon by Charles Haddon Spurgeon entitled "A New Order Of Priests And Levites."
