The Christian sermons contained in this volume are published in response to numerous requests that they might be put into permanent form. The author of these sermons needs no introduction to the Christian readers of America. His fame as an author, preacher and evangelist is more than national. As Director of the evangelistic work carried on by the General Assembly's Committee of the Presbyterian Church, he has achieved distinction as a preacher of the Gospel. Under his direction simultaneous evangelistic campaigns have been held in many of the leading cities of the land, and the Christian Church and the world have had an experience of a new, aggressive and emphatic evangelism that has stirred the Church, revived Christian service and been the means under God of turning thousands to a life of allegiance to Jesus Christ.
