As Christians we face two tasks in our evangelism: saving the soul and saving the mind, that is to say, not only converting people spiritually, but converting them intellectually as well. And the Church is lagging dangerously behind with regard to this second task. If the church loses the intellectual battle in one generation, then evangelism will become immeasurably more difficult in the next. The war is not yet lost, and it is one which we must not lose: souls of men and women hang in the balance. For the sake of greater effectiveness in witnessing to Jesus Christ Himself, as well as for their own sakes, evangelicals cannot afford to keep on living on the periphery of responsible intellectual existence. Thinking about your faith is indeed a virtue, for it helps you to better understand and defend your faith. — William Lane Craig (from, Hard Questions, Real Answers)
