And though it is somewhat tantalising not to know more about this future life, very possibly we are not told more, because we should not be able to understand it if we were. Even in this world it is doubtful if a savage or a young child could understand the intellectual life of a civilised man, however carefully it might be explained to him; and practically certain that an ape could not. And for all we know our own future life may be as far beyond our present understanding. It is the _Great Surprise_ in store for us all. But however much we may be changed, our personal identity will still remain, _I shall be I, and you will be you_, with much the same characters as we have at present. This is the important point, and of this we may be quite sure. Lastly, as to _Eternity_. Christianity, it is true, can say little here, but that little is full of hope. It opens up boundless possibilities, far more than any other religion. For by the Incarnation human nature has been united to the Divine, and thus raised to a position second only to that of God Himself. No destiny, then, that can be imagined is too great for man. Created in the image of the Triune God, with a supernatural freedom of choice; his nature united to God's by the Incarnation; his sins forgiven through the Atonement; his body purified and spiritualised at its Resurrection--surely the end of all this cannot be any mere monotonous existence, but rather one of ceaseless joy and activity. Heaven has been called the _last act_ in God's drama of the universe. And considering the magnitude of the previous acts--the formation of the solar system, the development of organic life, etc.--we should expect this last act to be on a scale equally vast and magnificent, and as far above anything we can imagine as the life of a butterfly is above the imagination of a chrysalis. Now the conclusion to be drawn from all this is quite plain. Christianity is so adapted to man's nature that it probably came from the Author of man's nature; just as if a complicated key fits a complicated lock, it was probably made by the same locksmith. And since Christianity is meant for all mankind, and the vast majority of men have neither time nor ability to examine its proofs, the fact of its thus appealing direct to human nature is certainly a strong argument in its favour.
