Death ensues because certain relations in the organism are not adjusted to certain relations in the Environment. There will come a time in each history when the imperfect correspondences of the organism will betray themselves by a failure to compass some necessary adjustment. This is why Death is associated with Imperfection. Death is the necessary result of Imperfection, and the necessary end of it. Imperfect correspondence gives imperfect and uncertain Life. "Perfect correspondence," on the other hand, according to Mr. Herbert Spencer, would be "perfect Life." To abolish Death, therefore, all that would be necessary would be to abolish Imperfection. But it is the claim of Christianity that it can abolish Death. And it is significant to notice that it does so by meeting this very demand of Science--it abolishes Imperfection.
The part of the organism which begins to get out of correspondence with the Organic Environment is the only part which is in vital correspondence with it. Though a fatal disadvantage to the natural man to be thrown out of correspondence with this Environment, it is of inestimable importance to the spiritual man. For so long as it is maintained the way is barred for a further Evolution. And hence the condition necessary for the further Evolution is that the spiritual be released from the natural. That is to say, the condition of the further Evolution is Death. _Mors janua Vitae_, therefore, becomes a scientific formula. Death, being the final shifting of all the correspondences, is the indispensable factor of the higher Life. In the language of Science, not less than of Scripture, "To die is gain."
The shifting of the correspondences is done by Nature. This is its last and greatest contribution to mankind. Over the mouth of the grave the perfect and the imperfect submit to their final separation. Each goes to its own--earth to earth, ashes to ashes, dust to dust, Spirit to Spirit. "The dust shall return to the earth as it was; and the Spirit shall return unto God who gave it."
