The Creator of man has arranged the living machinery of our bodies. Every function is wonderfully and wisely made. And God pledged Himself to keep this human machinery in healthful action if the human agent will obey His laws and cooperate with God. Every law governing the human machinery is to be considered just as truly divine in origin, in character, and in importance as the word of God. Every careless, inattentive action, any abuse put upon the Lord's wonderful mechanism, by disregarding His specified laws in the human habitation, is a violation of God's law. We may behold and admire the work of God in the natural world, but the human habitation is the most wonderful.364Counsels on Diet and Foods, 17 CCh 215.5
Since the laws of nature are the laws of God, it is plainly our duty to give these laws careful study. We should study their requirements in regard to our own bodies and conform to them. Ignorance in these things is sin. CCh 215.6
When men and women are truly converted, they will conscientiously regard the laws of life that God has established in their being, thus seeking to avoid physical, mental, and moral feebleness. Obedience to these laws must be made a matter of personal duty. We ourselves must suffer the ills of violated law. We must answer to God for our habits and practices. Therefore the question for us is not, “What will the world say?” but, “How shall I, claiming to be a Christian, treat the habitation God has given me? Shall I work for my highest temporal and spiritual good by keeping my body as a temple for the indwelling of the Holy Spirit, or shall I sacrifice myself to the world's ideas and practices?”365Testimonies for the Church 6:369, 370 CCh 215.7
