Every powerful movement has had its philosophy which has gripped the mind, fired, the imagination and captured the devotion of its adherents. (12)
Much of today’s world is dominated by ideologies which, if not totally false, are alien to the gospel of Christ. […] Our Christian crusade is far different from the shameful crusades of the Middle Ages. [Here Stott points us to 2 Cor. 10:4-5: “For the weapons of our warfare are not carnal but mighty in God for pulling down strongholds, casting down arguments and every high thing that exalts itself against the knowledge of God, bringing every thought into captivity to the obedience of Christ”]
This is a battle of ideas, God’s truth overthrowing the lies of men. Do we believe in the power of the truth? (13)
My argument now is that the great doctrines of creation, revelation, redemption and judgment all imply that man has an inescapable duty both to think and act upon what he thinks and knows. (14)
-John Stott, Your Mind Matters, 12-14.
