A most reasonable thing…

God has put enough in this world to make faith in Him a most reasonable thing; He has left enough out to make it impossible to live by sheer reason alone.

Ravi Zacharias, from “Finding Answers Amid Life’s Greatest Losses” at 1:00:15

Man’s reason cannot grasp…

That while man can by his reason alone know that God is…, man’s reason cannot grasp what He is.

Thomas Aquinas, quoted in Roman Catholics and Evangelicals: Agreements and Differences by Norman Geisler, p. 42
