And the fact that the teaching of the Bible, though when examined afterwards it turns out to be development or evolution, yet was always given at the time as a revelation, so far from diminishing the force of this internal evidence adds to it still more force than it would otherwise have. For what underlies the very conception of revelation is the doctrine that all progress in higher spiritual knowledge is bound up with conscious communion with God. Now it is an experience common to all believers that in that communion is to be found not only all strength but all enlightenment also. The believer knows that he learns spiritual truth in proportion as he refers his life to God's judgment, prays to God for clearer vision of what is duty and what is right faith, and makes it his one great aim to do God's will. He uses all the faculties that God has given him to understand the great divine law; but he perpetually looks to God for instruction, and whatever else may be said of that instruction his experience tells him that his advance in spiritual knowledge is in proportion to his nearness in thought and feeling to God Himself. That the progress of the human race in spiritual knowledge, unlike progress in scientific knowledge, should be due not to thinkers intellectually gifted, but to Prophets and Apostles inspired by God, thus exactly corresponds with what the spiritually-minded man finds within his own soul. And so too does it correspond with what he sees in others. Often and often the unlearned and untrained by sheer goodness of life attain to wonderful perception of spiritual truth, and the holiness of the unlettered peasant reveals to his conscience the law of right conduct in circumstances which perplex the disciplined and well informed. As the human race has learnt the highest spiritual truth by direct communication from God, so too on communion with God far more than on intellectual power, depends the progress of spiritual knowledge in every human soul.
