After her timely correction of erroneous teachings on faith, Mrs. Booth proceeds, pruning-knife in hand, to cut away from the tree of modern Christianity the poisonous fungus of a "spurious charity." Her four sermons on _Charity_ are four beacons set on the rocks of counterfeit Christian love. She sets forth several infallible tests by which genuine love may be distinguished from the devil's base imitation. Like the Epistles of St. John, these sermons are full of touchstones for testing love, that golden principle of the Christian life. It would be very profitable for all professors of that perfect love which casteth out all tormenting fear, to apply unflinchingly these touch-stones to themselves. They may find the word "perfection" taking on a meaning deeper, broader and higher than they had ever before conceived. Why should not our conception of Christian perfection steadily grow with the increase of our knowledge of God and of His holy law? The sermon on _The Conditions of Effectual Prayer_, we commend to all Christians and to all seekers of Christ, who are mourning because their prayers do not prevail with God. In the clear light of this sermon they will find that the difficulty lies, either in the lack of fellowship with Jesus Christ, or of obedience to His commands, or in the absence from their hearts of the interceding Spirit, or in defective faith. In the discussion of these hindrances to prayer, the preacher lays open the heart, and with a skilful spiritual surgery, searches it to the very bottom. The incisiveness of her style, her courage and plain dealing with her hearers, tearing off the masks of sin and selfishness, the various guises in which these masquerade in many Christian hearts and obstruct their access to a throne of grace, remind us of Dr. Finney's unsparing exposure and condemnation of these foes to Christian holiness, and of John Wesley's cutting up by the roots "Sin in Believers."
