Many modern people, Christians included, treat faith as a strange mystical way of knowing that is unconnected to reason or evidence. It is a zero-sum game in which the more reason and evidence you have, the less of a role is left for faith to play. The New Testament, however, knows nothing of such ideas. For the biblical writers, faith is simply trust, and salvation is granted to people who put their personal trust in Christ as God’s Messiah. You could conceivably have that trust for good reasons, bad reasons, or no reasons. It is better to have good reasons. Luke says that Jesus offered “many convincing proofs” of His resurrection (Acts 1:3), and early preachers such as the apostle Paul were constantly giving reasons and evidence to back up their message. So we could say that apologetics is based on a biblical precept (Peter’s command), biblical precedent (the apostles’ example), and a biblical principle (that the gospel is truth that should be addressed to the whole person, including the mind). —Donald T.
