The sermons of Mrs. Booth already re-published under the title of 'Aggressive Christianity', came to American Christians as a tonic to their weakness, and a stimulant to their inertness. The sermons in the present volume are a much-needed prophylactic, a safeguard against several practical errors in dealing with souls; errors which lead them into Egyptian darkness, instead of the marvelous light. The sermon on Repentance is a most faithful showing up of spurious repentance, the vain substitute for a downright abandonment of every form of sin, and right-about facing towards the Lord. In directness and point, it is a model for earnest revival preaching, --rather, for all preaching to unsaved souls, outside the church, or within it. All of these will be found in some subterfuge, which must be ruthlessly torn down, before it will be abandoned for the cleft Rock. The sermon on Saving Faith is next in order. The disastrous consequences of what, for the want of a better description, maybe styled an Antinomian faith, an unrepentant assent of the intellect to the historic facts of the Gospel, which too many evangelists and other religious teachers are calling saving faith, are clearly set forth and plainly labeled, POISON. This spurious trust in Christ following a superficial repentance, which has never felt the desperate sinfulness and real misery of sin, has furnished our churches with a numerous class of members, aptly described by the prophet Micah: 'The sin of Israel is great and unrepented of, yet they will lean on the Lord, and say, Is not the Lord among us?
