December 10, 1871, I was again shown that the health reform is one branch of the great work which is to fit a people for the coming of the Lord. It is as closely connected with the third angel's message as the hand is with the body. The law of Ten Commandments has been lightly regarded by man, but the Lord would not come to punish the transgressors of that law without first sending them a message of warning. The third angel proclaims that message. Had men ever been obedient to the law of Ten Commandments, carrying out in their lives the principles of those precepts, the curse of disease now flooding the world would not be. 1TT 320.1
Men and women cannot violate natural law by indulging depraved appetite and lustful passions, and not violate the law of God. Therefore He has permitted the light of health reform to shine upon us, that we may see our sin in violating the laws which He has established in our being. All our enjoyment or suffering may be traced to obedience or transgression of natural law. Our gracious heavenly Father sees the deplorable condition of men who, some knowingly but many ignorantly, are living in violation of the laws that He has established. And in love and pity to the race, He causes the light to shine upon health reform. He publishes His law and the penalty that will follow the transgression of it, that all may learn and be careful to live in harmony with natural law. He proclaims His law so distinctly and makes it so prominent that it is like a city set on a hill. All accountable beings can understand it if they will. Idiots will not be responsible. 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. 1TT 320.2
