genesis 1:28 And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth. - Free Bible Online

      28. Be fruitful, &c.--The human race in every country and age has been the offspring of the first pair. Amid all the varieties found among men, some black, some copper-colored, others white, the researches of modern science lead to a conclusion, fully accordant with the sacred history, that they are all of one species and of one family (Ac 17:26). What power in the word of God! "He spake and it was done. He commanded and all things stood fast" [Ps 33:9]. "Great and manifold are thy works, Lord God Almighty! in wisdom hast thou made them all" [Ps 104:24]. We admire that wisdom, not only in the regular progress of creation, but in its perfect adaptation to the end. God is represented as pausing at every stage to look at His work. No wonder He contemplated it with complacency. Every object was in its right place, every vegetable process going on in season, every animal in its structure and instincts suited to its mode of life and its use in the economy of the world. He saw everything that He had made answering the plan which His eternal wisdom had conceived; and, "Behold it was very good" [Ge 1:31].
