Studying the human body and nature fosters a positive view of health laws as blessings rather than sacrifices.

Original passage

Lead the people to study the manifestation of God's love and wisdom in the works of nature. Lead them to study that marvelous organism, the human system, and the laws by which it is governed. Those who perceive the evidences of God's love, who understand something of the wisdom and beneficence of His laws, and the results of obedience, will come to regard their duties and obligations from an altogether different point of view. Instead of looking upon an observance of the laws of health as a matter of sacrifice or self-denial, they will regard it, as it really is, as an inestimable blessing.
