1 Thessalonians 5:25 - "Brethren, pray for us."
You ought to pray for those, whom "the Holy Ghost hath made OVERSEERS over you." This is what St. Paul begs, again and again, of the churches to whom he writes: Says he in the text, "Brethren, pray for us;" and again, in his epistle to the Ephesians, "praying always, with all manner of supplication; and for me also, that I may open my mouth boldly, to declare the mystery of the gospel." And in another place, to express his earnestness in this request, and the great importance of their prayers for him, he bids the church "strive, (or, as the original word signifies, be in an agony) together with him in their prayers." And surely, if the great St. Paul, that chosen vessel, that favorite of heaven, needed the most importunate prayers of his Christian converts; much more do the ordinary ministers of the gospel stand in need of the intercession of their respective flocks.
And I cannot but in a more especial manner insist upon this branch of your duty, because it is a matter of such importance: for, no doubt, much good is frequently withheld from many, by reason of their neglecting to pray for their ministers, and which they would have received, had they prayed for them as they ought. Not to mention, that people often complain of the want of diligent and faithful pastors. But how do they deserve good pastors, who will not earnestly pray to God for such? If we will not pray to the Lord of the harvest, can it be expected He will send forth laborers into His harvest?
Besides, what ingratitude is it, not to pray for your ministers! For shall they watch and labor in the word and doctrine for you, and your salvation, and shall not you pray for them in return? If any bestow favors on your bodies, you think it right, meet, and your bounden duty, to pray for them; and shall not they be remembered in your prayers, who daily feed and nourish your souls? Add to all this, that praying for your ministers, will be a manifest proof of your believing, that though Paul plant, and Apollos water, yet it is God alone who giveth the increase. And you will also find it the best means you can use, to promote your own welfare; because God, in answer to your prayers, may impart a double portion of His Holy Spirit to them, whereby they will be qualified to deal out to you larger measures of knowledge in spiritual things, and be enabled more skillfully to divide the word of truth.
Would men but constantly observe this direction, and when their ministers are praying in their name to God, humbly beseech Him to perform all their petitions: or, when they are speaking in God's name to them, pray that the Holy Ghost may fall on all them that hear the word; we should find a more visible good effect of their doctrine, and a greater mutual love between ministers and their people. For ministers hands would then be held up by the people's intercessions, and the people will never dare to villify or traduce those who are the constant subjects of their prayers.
