John Stott on Faith and Reason

17 I keep asking that the God of our Lord Jesus Christ, the glorious Father, may give you the Spirit of wisdom and revelation, so that you may know Him better. 18 I pray also that the eyes of your heart may be enlightened in order that you may know the hope to which He has called you, the riches of His glorious inheritance in the saints, 19 and His incomparably great power for us who believe. (Ephesians 1:17-19a, NIV 1984)

John Stott comments on the verses above: 

Divine illumination and human thought belong together. All our thinking is unproductive without the Spirit of truth; yet His enlightenment is not intended to save us the trouble of using our minds. It is precisely as we ponder what God has done in Christ that the Spirit will open our eyes to grasp its implications. It is commonly assumed that faith and reason are incompatible. This is not so. The two are never contrasted in Scripture, as if we had to choose between them. Faith goes beyond reason, but rests on it. Knowledge is the ladder by which faith climbs higher, the springboard from which it leaps farther.
