According to Nancy Pearsey, when young people who have abandoned the Christian faith are asked why, the most common answer is that they could not get answers to their questions about the faith. Thus they assumed that there were no answers and that the stories hey had been taught were just so many fairy tales.
This brings us right up against Peter’s command: “But sanctify the Lord God in your hearts: and be ready always to give an answer to every man that asketh you a reason of the hope that is in you with meekness and fear” (1 Peter 3:15). “Give an answer” is the English translation of apologia, the Greek word that Peter used. Thus apologetics simply means always being ready to give an answer when questions arise about our faith.
This does not mean that we need to be prepared with arguments that will overwhelm and overpower the skeptics — notice that Peter says “with meekness and fear.” But we should never avoid an honest question, even if we don’t know the answer. We simply need the confidence that answers do exist and to be willing to help the questioner search for those answers. If we are afraid to even do that, what hope is there for the future of Christianity?
