Five years ago there came into my life a spiritual experience that revolutionized my work, and resulted in a Ministry characterized by some of the manifestations that usually accompany Revivals. It was in this atmosphere that these messages were born; and while the writing of them has occupied the five intervening years, they but breathe the spirit that then prevailed. May God through them reveal to His servants the shallowness apparent in so much of our Modern Evangelism, and turn them to that deep and abiding work of the Holy Spirit which will alone stand the test of divine fire! Oswald J. Smith Toronto, 1922
