“A true knowledge of God and divine things is a practical knowledge. As to a mere speculative knowledge of the things of religion, many wicked men have attained to great measures of it. Men may possess vast learning, and their learning may consist very much of their knowledge in divinity, and of the Bible, and of the things pertaining to religion, and they may be able to reason very strongly about the attributes of God and the doctrines of Christianity, and yet herein their knowledge fails of being a saving knowledge, that it is only speculative and not practical.”
— Jonathan Edwards, Charity and Its Fruits (The Banner of Truth Trust, reprinted 1978) p. 226
