Readers of [John] Wesley and other great ministers of the past, such as Jonathan Edwards or Charles Finney, will easily see, if they know what it is they are looking at, how much use those ministers made of careful logic. Similarly for the great Puritan writers of an earlier period, and for later effective Christians such as C. S. Lewis and Francis Schaeffer. They all make relentless use of logic, and to great good effect. With none of these great teachers is it a matter of trusting logic instead of relying upon the Holy Spirit. Rather, they well knew, it is simply a matter of meeting the conditions along with which the Holy Spirit chooses to work. — Dallas Willard (from, Jesus The Logician)
