34. He who hungers and thirsts after God will seek for an understanding of the laws which the God of wisdom has impressed upon creation. These laws are a transcript of his character. They must control all who enter the heavenly and better country.—Unpublished Testimonies, August 30, 1896.HL 17.1

35. God's law is written by his own finger upon every nerve, every muscle, every faculty which has been entrusted to man.—Unpublished Testimonies, August 30, 1896.HL 17.2

Obedience to Law

36. God in his wisdom has established natural laws for the proper control of our dress, our appetites, and our passions, and he requires of us obedience in every particular.—The Review and Herald, October 16, 1883.HL 17.3

Physical Sin

37. The transgression of physical law is transgression of God's law. Our Creator is Jesus Christ. He is the author of our being. He is the author of the physical law as he is the author of the moral law. And the human being who is careless and reckless of the habits and practises that concern his physical life and health, sins against God. God is not reverenced, respected, or recognized. This is shown by the injury done to the body in violation of physical law.—Unpublished Testimonies, May 19, 1897.HL 17.4

Blessings Follow Obedience

38. God loves his creatures with a love that is both tender and strong. He has established the laws of nature; but his laws are not arbitrary exactions. Every “Thou shalt not,” whether in physical or moral law, contains or implies a promise. If it is obeyed, blessings will attend our steps; if it is disobeyed, the result is danger and unhappiness.—Testimonies For The Church 5:444.2.HL 17.5

39. Health, strength, and happiness depend upon immutable laws; but these laws cannot be obeyed where there is no anxiety to become acquainted with them.—The Health Reformer, September 1, 1871.HL 18.1

40. A knowledge of the laws by which health is secured and preserved is of pre-eminent importance.—Signs of the Times, August 26, 1886.HL 18.2

41. Indifference and ignorance in regard to the laws which govern our being are sins so common that we have learned to look upon them with undue tolerance.—The Health Reformer, February 1, 1877.HL 18.3

42. We have no right wantonly to violate a single principle of the laws of health.—The Review and Herald, July 29, 1884.HL 18.4

43. God is greatly dishonored by the way in which man treats his organism, and he will not work a miracle to counteract a perverse violation of the laws of life and health.—Unpublished Testimonies, August 30, 1896.HL 18.5

44. The Lord has made it a part of his plan that man's reaping shall be according to his sowing.—Unpublished Testimonies, May 19, 1897.HL 18.6

Heredity

45. Wherever the habits of the parents are contrary to physical law, the injury done to themselves will be repeated in future generations.—Unpublished Testimonies, January 11, 1897.HL 18.7

46. You should move out from principle, in harmony with natural law, irrespective of feeling.—Testimonies for the Church 3:76.HL 19.1

47. To make plain natural law, and urge the obedience of it, is the work that accompanies the third angel's message to prepare a people for the coming of the Lord.—Testimonies for the Church 3:161.HL 19.2

48. A flower of the field must have its root in the soil; it must have air, dew, showers, and sunshine. It will flourish only as it receives these advantages, and all are from God. So with man.—Special Instruction Relating to the Review and Herald Office, and The Work in Battle Creek, 36.HL 19.3

49. God calls for reformers to stand in defense of the laws he has established to govern the human system, and to maintain an elevated standard in the training of the mind and culture of the heart.—Special Testimonies, Series A 3:22.HL 19.4

Knowledge a Duty

50. It is the duty of every human being, for his own sake and for the sake of humanity, to inform himself or herself in regard to the laws of organic life, and conscientiously to obey them.... It is the duty of every person to become intelligent in regard to disease and its causes. You must study your Bible, in order to understand the value that the Lord places on the men whom Christ has purchased at such an infinite price. Then we should become acquainted with the laws of life, that every action of the human agent may be in perfect harmony with the laws of God. When there is so great peril in ignorance, is it not best to be wise in regard to the human habitation fitted up by our Creator, and over which he desires that we shall be faithful stewards?—Unpublished Testimonies, December 4, 1896.HL 19.5
