A Word On The Exclusivity Of Our Faith
The Christian faith is exclusive. It is exclusive because its Savior is the exclusive truth, life, and the only way to the Father (John 14:6). This sort of exclusivity bucks up against the anthem of this age, which is tolerance. Yet truth is by nature intolerant of falsehood. And truth becomes dogma the instant it is disputed. Truth, however, is worth fighting for. If the people of Christ, whose exclusive claim is truth, do not defend it, who will? Chesterton wrote these sobering words in his work, Orthodoxy: “We are on the road to producing a race of men too mentally modest to believe in the multiplication table. We are in danger of seeing philosophers who doubt the law of gravity as being a mere fancy of their own.” Humanity governs its life according to truth principles. Engineers estimate the loadbearing weight of a crossbeam and build accordingly. Parents operate under the truth that soap kills the germs on their children’s hands. Doctors understand that cancer kills and any attempt of saving life depends on destroying the cancerous cells. Jesus said He was the truth. A Christian's job is to beckon the world to see this truth and govern their lives accordingly.
