Samuel Logan Brengle (1860-1936) was an American Methodist born in Indiana who joined the Salvation Army in the 1890s. He was mightily used of the Lord–even more so through his many books. He was described by one observer as a kindly, literate and articulate man who left good memories with nearly
everyone he met.

Colonel Brengle’s books need no recommendation. Dealing as they do with what is and ever must be to the sincere follower of Christ, the most vitally important among spiritual subjects, namely, holiness of heart and life, they constitute a valuable guide to the promises.

Writing from the battlefield of actual warfare, dealing individually with hundreds of souls, mingling daily with the working classes, the writer thoroughly grasps the needs of his readers. His language is that of the people.

We heartily commend this volume to all who desire to tread the blessed pathway of peace, of purity and of power for service. – F. Booth Tucker
