Here is a description of the book:
Description: Jonathan Edwards (1703-1758) is best known as the theologian of revival. In this, his major study on the theme, he analyses the nature of a genuine work of the Holy Spirit. He was one of the few truly great theologians of the English speaking world, an intellectual and spiritual giant. Of his several treatises in this field, The Religious Affections ranks as ëmagnum opusí. The author's object in this book is to distinguish between true and false religion by showing the marks of a saving work of the Holy Spirit in men. In his Preface, Edwards stresses the importance of using "our utmost endeavours clearly to discern...wherein true religion does consist." For "till this be done, it may be expected that great revivings of religion will be but of short continuance."
This is simply one of the best Christian books that was ever written. Worth mastering in your lifetime. Edwards searches the depths of the human heart and bibically drives home an affectional theology. Profound!
