Immortality (n.) as the hope of a future life is merely the expectation of a miracle of resurrection.
Immortality (n.) is not something we can know but something the moral law requires us to assume — our ignorance looks like a loss and is in fact a gain.
Immortality (n.) finds a doctrinal ground in the mismatch between the magnificent equipment of human nature and the shortness of a life so ill suited to it.
