Science never corroborates a spiritual truth without illuminating it. The threshold of Eternity is a place where many shadows meet. And the light of Science here, where everything is so dark, is welcome a thousand times. Many men would be religious if they knew where to begin; many would be more religious if they were sure where it would end. It is not indifference that keeps some men from God, but ignorance. "Good Master, what must I do to inherit Eternal Life?" is still the deepest question of the age. What is Religion? What am I to believe? What seek with all my heart and soul and mind?--this is the imperious question sent up to consciousness from the depths of being in all earnest hours; sent down again, alas, with many of us, time after time, unanswered. Into all our thought and work and reading this question pursues us. But the theories are rejected one by one; the great books are returned sadly to their shelves, the years pass, and the problem remains unsolved. The confusion of tongues here is terrible. Every day a new authority announces himself. Poets, philosophers, preachers, try their hand on us in turn. New prophets arise, and beseech us for our soul's sake to give ear to them--at last in an hour of inspiration they have discovered the final truth. Yet the doctrine of yesterday is challenged by a fresh philosophy to-day; and the creed of to-day will fall in turn before the criticism of to-morrow. Increase of knowledge increaseth sorrow. And at length the conflicting truths, like the beams of light in the laboratory experiment, combine in the mind to make total darkness.
But here are two outstanding authorities agreed--not men, not philosophers, not creeds. Here is the voice of God and the voice of Nature. I cannot be wrong if I listen to them. Sometimes when uncertain of a voice from its very loudness, we catch the missing syllable in the echo. In God and Nature we have Voice and Echo. When I hear both, I am assured. My sense of hearing does not betray me twice. I recognize the Voice in the Echo, the Echo makes me certain of the Voice; I listen and I know. The question of a Future Life is a biological question. Nature may be silent on other problems of Religion; but here she has a right to speak. The whole confusion around the doctrine of Eternal Life has arisen from making it a question of Philosophy. We shall do ill to refuse a hearing to any speculation of Philosophy; the ethical relations here especially are intimate and real. But in the first instance Eternal Life, as a question of _Life_, is a problem for Biology. The soul is a living organism. And for any question as to the soul's Life we must appeal to Life-science. And what does the Life-science teach? That if I am to inherit Eternal Life, I must cultivate a correspondence with the Eternal. This is a simple proposition, for Nature is always simple. I take this proposition, and, leaving Nature, proceed to fill it in. I search everywhere for a clue to the Eternal. I ransack literature for a definition of a correspondence between man and God. Obviously that can only come from one source. And the analogies of Science permit us to apply to it. All knowledge lies in Environment. When I want to know about minerals I go to minerals. When I want to know about flowers I go to flowers. And they tell me. In their own way they speak to me, each in its own way, and each for itself--not the mineral for the flower, which is impossible, nor the flower for the mineral, which is also impossible. So if I want to know about Man, I go to his part of the Environment. And he tells me about himself, not as the plant or the mineral, for he is neither, but in his own way. And if I want to know about God, I go to His part of the Environment. And he tells me about Himself, not as a Man, for He is not Man, but in His own way. And just as naturally as the flower and the mineral and the Man, each in their own way, tell me about themselves, He tells me about Himself. He very strangely condescends indeed in making things plain to me, actually assuming for a time the Form of a Man that I at my poor level may better see Him. This is my opportunity to know Him. This incarnation is God making Himself accessible to human thought--God opening to man the possibility of correspondence through Jesus Christ. And this correspondence and this Environment are those I seek. He Himself assures me, "This is Life Eternal, that they might know Thee, the only true God, and Jesus Christ whom Thou has sent." Do I not now discern the deeper meaning in "_Jesus Christ whom Thou has sent?_" Do I not better understand with what vision and rapture the profoundest of the disciples exclaims, "The Son of God is come, and hath given us an understanding that we might know Him that is True?"
