Edwards's first publication (1731) was a sermon preached in Boston on 'God Glorified in Man's Dependence.' The conditions under which it was produced afford striking contrasts to those attendant upon Schleiermacher's epoch-making 'Reden ueber Religion'; but the same note of absolute dependence upon God is struck by each with masterly power. A yet more characteristic and deeply spiritual utterance was given in the next published discourse, entitled 'A Divine and Supernatural Light Immediately Imparted to the Soul by the Spirit of God, Shown to be both a Scriptural and Rational Doctrine' (1734). These two sermons are of primary significance for a right understanding of their author's teaching. All is of God; faith is sensibleness of what is real in the work of redemption; this reality is divinely and transcendently excellent; this quality of it is revealed to the soul by the Holy Spirit, and becomes the spring of all holiness. "The central idea of his system," says Henry B. Smith, "is that of spiritual life (holy love) as the gift of divine grace." All of Edwards's other writings may be arranged in relation to this principle,--as introductory, explicative, or defensive. When the sermon on the 'Reality of Spiritual Light' was delivered, the movement had begun which, as afterwards extended from Northampton to many communities in New England and beyond, is known as "The Great Awakening." The preaching of Edwards was a prominent instrumentality in its origination, and he became its most effective promoter and champion, and no less its watchful observer and critic. Among the published (1738) sermons which it occasioned should be specially mentioned those on 'Justification by Faith Alone,' 'The Justice of God in the Damnation of Sinners,' 'The Excellency of Jesus Christ,' 'The Distinguishing Marks of a Work of the Spirit of God, applied to that uncommon operation that has lately appeared on the minds of many of the people of New England: with a particular consideration of the extraordinary circumstances with which this work is attended' (1741). The same year (1741) appeared the sermon on 'Sinners in the Hands of an Angry God.' Some five years previous, moved by the notice taken in London by Dr. Watts and Dr. Guise of the religious revival in Northampton and several other towns, and by a special request from Rev. Dr. Colman of Boston, Edwards prepared a careful 'Narrative,' which, with a preface by the English clergymen just named, was published in London in 1737, and the year following in Boston. The sermon on the 'Distinguishing Marks of a Work of the True Spirit of God' was followed by the treatise entitled 'Some Thoughts Concerning the Present Revival of Religion, and the way in which it ought to be acknowledged and promoted' (1742); and four years later, by the elaborate work on 'Religious Affections.' The latter sums up all that Edwards had learned, through his participation in the movement whose
