" And the impressing divine things on the hearts and affections of men, is evidently one great and main end for which God has ordained that his word delivered in the holy Scriptures, should be opened, applied, and set home upon men, in preaching. And therefore it does not answer the aim which God had in this institution, merely for men to have good commentaries and expositions on the Scripture, and other good books of divinity; because, although these may tend as well as preaching to give men a good doctrinal or speculative understanding of the things of the word of God, yet they have not an equal tendency to impress them on men's hearts and affections. "
