I just stumbled across this website--JonathanEdwards.com. It is a great resource for anyone wanting to learn more about the great preacher of the 1700's. The website lists dozens of sermons, theological writings, and scientific writings, as well as biographical sketches. An excerpt from The Life and Character of the Late Reverend Mr. Jonathan Edwards by Samuel Hopkins:
This is the beginning of a life so eminently holy and useful as Mr. Edwards’ was. He who became one of the greatest divines in this age; has had the applause and admiration of America, Britain, Holland and Germany, for his piety, and great judgment and skill in divinity; and has been honored above most others in the Christian world, in this century; in his being made the instrument of doing so much good: he began his life thus: he entered on a public life with such views, such exercises, such resolutions. This may serve as a direction and excitement to those who are young, to devote themselves to God in good earnest, and enter on the business of strict and thorough religion without delay: especially those who are looking towards the work of the ministry, as they would take the most direct, the only way to answer the good ends which they profess to seek.
Edwards was certainly a brilliant man--skimming through his scientific writings confirms that. He was also a godly man who strove to walk closer to God.
