If you study your own body, you will find its mechanism to be the original model of the artificial mechanism of the world. Art and science fail if compared with that of His nature. The ear, eyes, and all other organs, how perfectly they are adapted in shape and mechanism to the purpose which they must serve! How liberally the needs of life, water, air, and food, are supplied; even milk is prepared in the mother's breast for the unborn infant. Should we not appreciate the liberality of the Creator, and thank him each moment with all humility and gratitude?
