Every enlargement of our knowledge of organic nature is an addition to the already numberless instances of recognized special adaptation which crowd us on every hand; and all scientific discovery is but an illustration and a verification of the _à priori_ intuition of the reason that a principle of design is co-extensive with and the highest law of the universe. Not merely of each individual existence, but of the grand totality of existence, are we constrained to believe that it exists for a purpose. Above all special ends there is a great ultimate design of creation--a last or final end to which all intermediate ends are means; and though physical science can not fully compass that final purpose, yet in the light of its present knowledge of special ends it has abundant reason for assuming that there _must_ be a final purpose, and that that final purpose is at once beneficent and wise.[181] But while the final purpose of creation may not be discoverable by human science, we know that it has been revealed in the Christian Scriptures. The most fundamental doctrine of Christianity is that _God is Love_ (1 John iv. 8, 16), and that Love is the highest determining principle of the Divine efficiency. Creation, Providence, and Redemption are grounded in Love as the final cause (Gen. i. 31; Isa. lxiii. 9; John iii. 16). The gravitating point of the Christian doctrine of "God the Creator" is not Omnipotence, nor yet Wisdom, but always Love. Omnipotence, in itself considered, possesses no moving or determining principle. God does not create the world to reveal his infinite power. Infinite Wisdom devises the best means and methods for the Divine efficiency, but it does not supply the ultimate reason why the world exists. The Love of God is the moving principle of his wisdom and power in that it appoints the _end_ to which omnipotence is related as the efficient, and wisdom as the formal cause. Whatever displays of power or of wisdom may be made in the created universe, they are all subordinated and made subservient to the purpose of Love. The highest law of the universe is Love. "The conservation of Love is the loftiest conservation of Force."
