Relation of Health to Character Building

God gives no permission to man to violate the laws of his being. But man, through yielding to Satan's temptations to indulge intemperance, brings the higher faculties into subjection to the animal appetites and passions. When these gain the ascendency, man, who was created a little lower than the angels, with faculties susceptible of the highest cultivation, surrenders to be controlled by Satan. And he gains easy access to those who are in bondage to appetite. Through intemperance, some sacrifice one-half, and others two-thirds, of their physical, mental, and moral powers and become playthings for the enemy.MYP 236.2

Those who would have clear minds to discern Satan's devices must have their physical appetites under the control of reason and conscience. The moral and vigorous action of the higher powers of the mind are essential to the perfection of Christian character. And the strength or the weakness of the mind has very much to do with our usefulness in this world, and with our final salvation. The ignorance that has prevailed in regard to God's law in our physical nature is deplorable. Intemperance of any kind is a violation of the laws of our being. Imbecility is prevailing to a fearful extent. Sin is made attractive by the covering of light which Satan throws over it, and he is well pleased when he can hold the Christian world in their daily habits under the tyranny of custom, like the heathen, and allow appetite to govern them.MYP 236.3
