[HT Dangerous Idea]
I am not asking anyone to accept Christianity if his best reasoning tells him that the weight of evidence is against it. That is not the point at which faith comes in. But supposing a man’s reason once decides that the weight of the evidence is for it. I can tell that man what is going to happen to him in the next few weeks. There will come a moment when there is bad news, or he is in trouble, or is living among a lot of other people who do not believe it, and all at once his emotions will rise up and carry out a sort of blitz on his belief. Or else there will come a moment when he wants a woman, or wants to tell a lie, or feels very pleased with himself, or sees a chance of making a little money in some way that is not perfectly fair; some moment, in fact, at which it would be very convenient if Christianity were not true. –CS Lewis, Mere Christianity
Faith is not opposed to reason. True Biblical faith, the kind Paul wrote about in 1 Corinthians 15, is based squarely in truth, facts, logic, and reason and not in blind flights of fancy based in emotions and wish-fulfillment. Not that our faith is devoid of emotion or that our life in Christ is detachable from powerful experiences. However we must remember that our faith is first of all grounded in truth which is both rational and testable.
