The truth of the religious experiences recorded in the Bible is self-evidencing to him who shares these experiences, and to no one else. The Bible has, in a sense, to create or evoke the capacities by which it is appreciated and verified. It is inspired only to those who are themselves willing to be controlled by similar inspirations; it is the word of God only to those who have ears for God's voice. There is a difference between the phrases: "It is certain," and "I am certain." In other matters we appeal to the collective opinion of sane people; but such knowledge does not suffice in religion. Our fellowship with God must be our own response to our highest inspirations. The Bible is authoritative for us only in so far as we can say: "I have entered into the friendship of the God, whose earlier friendship with men it records, and know Him, who speaks as personally to my conscience through its pages, as He spake to its writers. The Spirit that ruled them, the Spirit of trust and service, controls me." This is John Calvin's position. "It is acting a preposterous part," he writes in his _Institutes_, "to endeavor to produce sound faith in the Scriptures by disputations. Religion appearing to profane men to consist wholly in opinion, in order that they may not believe anything on foolish or slight grounds, they wish and expect it to be proved that Moses and the prophets spake by divine inspiration; but as God alone is a sufficient witness of Himself in His own word, so also the word will never gain credit in the hearts of men, till it is confirmed by the testimony of the Spirit."
