God had an important work for the promised child of Manoah to do, and it was to secure for him the qualifications necessary for this work that the habits of both the mother and the child were to be carefully regulated. “Neither let her drink wine or strong drink,” was the Angel’s instruction for the wife of Manoah, “nor eat any unclean thing. All that I commanded her let her observe.” Judges 13:14. The child will be affected for good or for evil by the habits of the mother. She must herself be controlled by principle and must practice temperance and self-denial, if she would seek the welfare of her child. Unwise advisers will urge upon the mother the necessity of gratifying every wish and impulse, but such teaching is false and mischievous. The mother is by the command of God Himself placed under the most solemn obligation to exercise self-control. (PP 561.1) MC VC

And fathers as well as mothers are involved in this responsibility. Both parents transmit their own characteristics, mental and physical, their dispositions and appetites, to their children. As the result of parental intemperance children often lack physical strength and mental and moral power. Liquor drinkers and tobacco users may, and do, transmit their insatiable craving, their inflamed blood and irritable nerves, to their children. The licentious often bequeath their unholy desires, and even loathsome diseases, as a legacy to their offspring. And as the children have less power to resist temptation than had the parents, the tendency is for each generation to fall lower and lower. To a great degree parents are responsible not only for the violent passions and perverted appetites of their children but for the infirmities of the thousands born deaf, blind, diseased, or idiotic.

The inquiry of every father and mother should be, “What shall we do unto the child that shall be born unto us?” Judges 13:8. The effect of prenatal influences has been by many lightly regarded; but the instruction sent from heaven to those Hebrew parents, and twice repeated in the most explicit and solemn manner, shows how this matter is looked upon by our Creator. (PP 561.3) MC VC

And it was not enough that the promised child should receive a good legacy from the parents. This must be followed by careful training and the formation of right habits. God directed that the future judge and deliverer of Israel should be trained to strict temperance from infancy. He was to be a Nazarite from his birth, thus being placed under a perpetual prohibition against the use of wine or strong drink. The lessons of temperance, self-denial, and self-control are to be taught to children even from babyhood. (PP 561.4) MC VC
