Here, Sean McDowell has written a fine article on why we should expose people to the objections to our faith. From my experience, unless people exposed to objections to our faith, then we will run into the issue of the difference between “feeling certain” and “being certain” which is discussed in the book Doubting Toward Faith
“Here’s a thought to digest: In the absence of certainty, there’s always room for doubt. And this applies not only to the Christian but to everyone. No one, in any belief system, can prove his or her faith with 100 percent certainty. But 100 percent certainty is also not required in order to believe in something or to have reasonable assurance that what you believe is true and trustworthy. • I believe my wife when she says she’ll be faithful to only me. • I believe my friends when they say, “I’m telling you the truth.” • I believe the red light will turn green in a reasonable amount of time. • I believe my government won’t collapse tomorrow.
But Bobby, I feel 100 percent certain that Christianity is true,” you may contest. And I would add, we cannot confuse feeling certain and being certain. There’s a difference. Mormons also feel certain their beliefs are true, as do Muslims, atheists, and many others. Feeling certain and being certain aren’t necessarily equivalent. As we all know, feelings are fickle. One day your moods may sing the praises of your faith and the next day your moods will betray you, drowning you in the despair of doubt. Many people who walk around saying “I know with 100 percent certainty that my faith is true” haven’t thought much about their faith. They’re often blissfully naïve, which insulates them from an onslaught of doubts.The reality is, even those who feel 100 percent certain can’t prove Christianity with 100 percent certainty. And we do the church a great disservice when we act like we can. Not to mention, we also set new believers up for a future doubt crisis when they realize things in our faith aren’t as tidy as they once thought. In any event, we must avoid two extremes, this time as it relates to certainty. On one extreme we have philosophers like René Descartes who seek certainty through doubting everything, and on the other extreme are those who doubt nothing in order to feel good about their supposed certainty. Neither solution is helpful.”
