John Stott 
Your Mind Matters [PDF ebook] 

"Knowledge is indispensable to Christian life and service, " writes John Stott. "If we do not use the mind which God has given us, we condemn ourselves to spiritual superficiality."While Christians have had a long heritage of rigorous scholarship and careful thinking, some circles still view the intellect with suspicion or even as contradictory to Christian faith. And many non-Christians are quick to label Christians as anti-intellectual and obscurantist. But this need not be so. In this classic introduction to Christian thinking, John Stott makes a forceful appeal for Christian discipleship that engages the mind as well as the heart.
