In Cooper’s novels there is a character whom he calls Leatherstocking, familiar with the woods, knowing all their signs, acquainted with the habits of bird, beast, and Indian. He guides the travellers through the wilderness, and, by his superior knowledge, saves them from the Indian ambush and the pursuing savage. They commit themselves implicitly to his guidance, trust their lives to him. Why? Because they confide in his knowledge of woodcraft and in his fidelity. As regards all matters pertaining to the forest, he is an authority; their teacher if they want information, their guide if they are ignorant of the way, their saviour in imminent peril from savage beasts and savage men. He is an authority to them, a perfect authority; for they confide in him entirely, without a shade of doubt. But no one thinks him infallible, nor supposes it necessary to believe him infallible, in order to trust him entirely. Just so a ship on a lee shore, in the midst of a driving storm, throws up signal rockets or fires a gun for a pilot. A white sail emerges from the mist; it is the pilot-boat. A man climbs on board, and the captain gives to him the command of the ship. All his orders are obeyed implicitly. The ship, laden with a precious cargo and hundreds of lives, is confided to a rough-looking man whom no one ever saw before, who is to guide them through a narrow channel, where to vary a few fathoms to the right or left will be utter destruction. The pilot is invested with absolute authority as regards bringing the vessel into port. When Columbus came back from his first voyage, and reported the discovery of America, was he not an _authority_? Did not men throng around him, to hear of what he had seen and done? Yet who believed him infallible. He who has been where I have not been, and seen what I have not seen, is an _authority_ to me. If I believe him honest, and no impostor, then I learn from him, and depend on his testimony. Now, the writers of the New Testament have been where we have not been. They have ascended heights, and sounded depths in the spiritual world unknown to us. So they are authorities to us, provided we have enough of their spirit in us to enable us to see and know their inspiration. For, unless I have some musical spirit in me, I cannot discern the inspiration of Mozart; unless I have some mathematical spirit in me, I cannot discern the mathematical inspiration of Newton and Kepler. So the natural man (the man who has nothing in him corresponding to the Christian inspiration) cannot discern the things of the Spirit of God; for they are foolishness to him, for they are spiritually discerned or judged. He lives in external things, as babes do. The authority of the Spirit in the Bible is that it awakens and appeals to whatever spiritual element exists in our soul, and compels it to feel and admit its truth.
