Conscious of God’s mighty works in other places, Spurgeon here stirs up the members of the church he serves to pray to God to accomplish what he alone can do, to cry out for the Holy Spirit. Spurgeon is emphatic about what the Spirit does and why we depend upon him utterly, and earnest about us getting on our knees to cry out for the mercies which he alone can bestow in bringing Christ into the hearts of men and making us truly to live for the praise of the glory of God. A wonderful call to prayer!
