Satan seeks to lower the standard of purity and to weaken the self-control of those who enter the marriage relation, because he knows that while the baser passions are in the ascendancy, the moral powers grow steadily weaker, and he need have no concern as to their spiritual growth. He knows, too, that in no way can he better stamp his own hateful image upon their offspring, and that he can thus mold their character even more readily than he can the character of the parents. CCh 134.6
Men and women, you will one day learn what is lust and the result of its gratification. Passion of just as base a quality may be found in the marriage relation as outside of it. CCh 135.1
What is the result of giving loose rein to the lower passions? The bedchamber, where angels of God should preside, is made unholy by unholy practices. And because shameful animalism rules, bodies are corrupted; loathsome practices lead to loathsome diseases. That which God has given as a blessing is made a curse. CCh 135.2
Sexual excess will effectually destroy a love for devotional exercises, will take from the brain the substance needed to nourish the system, and will most effectively exhaust the vitality. No woman should aid her husband in this work of self-destruction. She will not do it if she is enlightened and has true love for him. CCh 135.3
The more the animal passions are indulged, the stronger do they become, and the more violent will be their clamors for indulgence. Let God-fearing men and women awake to their duty. Many professed Christians are suffering with paralysis of nerve and brain because of their intemperance in this direction. CCh 135.4
