It is the belief of mankind that we shall all live forever. This is not a doctrine of Christianity alone. It belongs to the human race. You may find nations so rude that they live houseless, in caverns of the earth; nations that have no letters, not knowing the use of bows and arrows, fire or even clothes, but no nation without a belief in immortal life. The form of that belief is often grotesque and absurd; the mode of proof ridiculous; the expectations of what the future life is to be are often childish and silly. But notwithstanding all that, the fact still remains, the belief that the soul of a man never dies. How did mankind come by this opinion? "By a miraculous revelation," says one. But according to the common theory of miraculous revelations, the race could not have obtained it in this way, for according to that theory the heathen had no such revelations; yet we find this doctrine the settled belief of the whole heathen world. The Greeks and Romans believed it long before Christ; the Chaldees, with no pretence to miraculous inspiration, taught the idea of immortality; while the Jews, spite of their alleged revelations, rested only in the dim sentiment thereof. It was not arrived at by reasoning. It requires a good deal of hard thinking to reason out and prove this matter. Yet you find this belief among nations not capable as yet of that art of thinking and to that degree, nations who never tried to prove it, and yet believe it as confidently as we. The human race did not sit down and think it out; never waited till they could prove it by logic and metaphysics; did not delay their belief till a miraculous revelation came to confirm it. It came to mankind by intuition; by instinctive belief, the belief which comes unavoidably from the nature of man. In this same way came the belief in God; the love of man; the sentiment of justice. Men could see, and knew they could see, before they proved it; before they had theories of vision; without waiting for a miraculous revelation to come and tell them they had eyes, and might see if they would look. Some faculties of the body act spontaneously at first--so others of the spirit. Immortality is a fact of man's nature, so it is a part of the universe, just as the sun is a fact in the heavens and a part of the universe. Both are writings from God's hand; each therefore a revelation from Him, and of Him; only not miraculous, but natural, regular, normal. Yet each is just as much a revelation from Him as if the great Soul of all had spoken in English speech to one of us and said, "There is a sun there in the heavens, and thou shalt live for ever." Yes, the fact is more certain than such speech would make it, for this fact speaks always--a perpetual revelation, and no words can make it more certain.
