All this has greatly impoverished the spiritual life of both the individual Christian and the churches, and led to coldness, barrenness, and loss of power. The greatest need of the hour is a return to the emphases of the Evangelical Awakening. It is in the belief that this classic of the spiritual life and warfare can greatly stimulate and hasten that return that I encouraged my wife to translate it, and am now happy to commend it, and to advise all Christians to read it. I would particularly urge ministers and pastors to read it, not only because it will prove to be an invaluable help in what is now called counselling of individuals, but also because I would press upon them the importance of introducing such meetings into the life of their churches. Much untold blessing would follow.
