To prove that there is an existence beyond the change which we name Death, has always been earnestly desired. Today the world of Christian theology admits that, aside from revelation, there is no absolute proof of a future life, but only cumulative evidence.
To the Christian Scientist this is not so. We set out, as does the mathematician, with axioms, or higher truths. These are recognized as true, not because they can be demonstrated, but because they must be true; and from them follows the inevitable affirmation, through a purely logical process.
For instance, take the Biblical idea, in accordance with revelation, and let it be granted:
First, That God is eternal, or that He is unending existence.
Second, That man is in His likeness and image, or like Him.
Third. Then it necessarily follows that the realm of man is also eternal, and must have an unending existence.
