As I travel, I've also had the experience of meeting other people who've told me of how they've been saved from apparent apostasy through reading an apologetic book or seeing a video of a debate. In their case apologetics has been the means by which God has brought about their perseverance in the faith. Now, of course, apologetics cannot guarantee perseverance, but it can help and in some cases may, in the providence of God, even be necessary. For example, after a lecture at Princeton University on arguments for the existence of God, I was approached by a young man who wanted to talk with me. Obviously trying to hold back the tears, he told me that a couple of years earlier he had been struggling with doubts and was on the brink of abandoning his faith. Someone then gave him a video of one of my debates. He said, "It saved me from losing my faith. I cannot thank you enough."

I said, "It was the Lord who saved you from falling."

"Yes," he replied, "but he used you. I can't thank you too much." I told him how thrilled I was for him and asked him about his future plans. "I'm graduating this year," he told me, "and I plan to go to seminary. I'm going into the pastorate." Praise God for the victory in this young man's life!

But Christian apologetics does much more than safeguard against lapses. The positive, upbuilding effects of apologetic training are even more evident. American churches are filled with Christians who are idling in intellectual neutral. As Christians, their minds are going to waste. One result of this is an immature, superficial faith. People who simply ride the roller coaster of emotional experience are cheating themselves out of a deeper and richer Christian faith by neglecting the intellectual side of that faith. They know little of the riches of deep understanding of Christian truth, of the confidence inspired by the discovery that one's faith is logical and fits the facts of experience, and of the stability brought to one's life by the conviction that one's faith is objectively true. One of the most gratifying results of the annual apologetics conferences held by the Evangelical Philosophical Society in local churches during the course of our annual conventions is to see the light come on in the minds of many laymen when they discover for the first time in their lives that there are good reasons to believe that Christianity is true and that there is a part of the body of Christ that they never knew existed that wrestles regularly with the intellectual content of the Christian faith.4

I also see the positive effects of apologetics when I debate on university campuses. Typically I'll be invited onto a campus to debate some professor who has a reputation of being especially abusive to Christian students in his classes. We'll have a public debate on, say, the existence of God, or Christianity versus humanism, or some such topic. Again and again I find that while most of these men are pretty good at beating up intellectually on an eighteen-year-old in one of their classes, they can't even hold their own when it comes to going toe-to-toe with one of their peers. John Stackhouse once remarked to me that these debates are really a Westernized version of what missiologists call a "power encounter." I think that's a perceptive analysis. Christian students come away from these encounters with a renewed confidence in their faith, their heads held high, proud to be Christians, and bolder in speaking out for Christ on their campus.

Many Christians do not share their faith with unbelievers simply out of fear. They're afraid that the non-Christian will ask them a question or raise an objection that they can't answer. And so they choose to remain silent and thus hide their light under a bushel, in disobedience to Christ's command. Apologetics training is a tremendous boost to evangelism, for nothing inspires confidence and boldness more than knowing that one has good reasons for what one believes and good answers to the typical questions and objections that the unbeliever may raise.
