This passage is part of a sermon by C.H. Spurgeon in 1866, and so it is a not a simple read, but will benefit any who will put in the time to understand.
While a true revival in its essence belongs only to God’s people, it always brings with it a blessing for the other sheep who are not yet of the fold. If you drop a stone into a lake the ring widens continually, till the farthest corner of the lake feels the influence. Let the Lord revive a believer and very soon his family, his friends, his neighbors, receive a share of the benefit; for when a Christian is revived, he prays more fervently for sinners. Longing, loving prayer for sinners, is one of the marks of a revival in the renewed heart. Since the blessing is asked for sinners, the blessing comes from him who hears the prayers of his people; and thus the world gains by revival. Soon the revived Christian speaks concerning Jesus and the gospel; he sows good seed, and God’s good seed is never lost, for he has said, “It shall not return unto me void.” The good seed is sown in the furrows, and in some sinners’ hearts God prepares the soil, so that the seed springs up in a glorious harvest. Thus by the zealous conversation of believers another door of mercy opens to men.
When Christians are revived they live more consistently, they make their homes more holy and more happy, and this leads the ungodly to envy them, and to enquire after their secret. Sinners by God’s grace long to be like such cheerful happy saints; their mouths water to feast with them upon their hidden manna, and this is another blessing, for it leads men to seek the Savior. If an ungodly man steps into a congregation where all the saints are revived he does not go to sleep under the sermon. The minister will not let him do that, for the hearer perceives that the preacher feels what he is preaching, and has a right to be heard. This is a clear gain, for now the man listens with deep emotion; and above all, the Holy Spirit’s power, which the preacher has received in answer to prayer comes upon the hearer’s mind; he is convinced of sin, of righteousness, and of judgment to come, and Christians who are on the watch around him hasten to tell him of the Savior, and point him to the redeeming blood, so that though the revival, strictly speaking, is with the people of God, yet the result of it no man can limit.
