Vital Energy Is Depleted—The practice of secret habits surely destroys the vital forces of the system. All unnecessary vital action will be followed by corresponding depression. Among the young the vital capital, the brain, is so severely taxed at an early age that there is a deficiency and great exhaustion, which leaves the system exposed to disease of various kinds.^{1An Appeal to Mothers, 28.}CG 444.1

Foundation Laid for Various Diseases Later in Life—If the practice is continued from the ages of fifteen and upward, nature will protest against the abuse she has suffered, and continues to suffer, and will make them pay the penalty for the transgression of her laws, especially from the ages of thirty to forty-five, by numerous pains in the system and various diseases, such as affection of the liver and lungs, neuralgia, rheumatism, affection of the spine, diseased kidneys, and cancerous humors. Some of nature's fine machinery gives way, leaving a heavier task for the remaining to perform, which disorders nature's fine arrangement; and there is often a sudden breaking down of the constitution, and death is the result.^{2An Appeal to Mothers, 18.}CG 444.2

The Sixth Commandment Is Thoughtlessly Violated—To take one's life instantly is no greater sin in the sight of heaven than to destroy it gradually, but surely. Persons who bring upon themselves sure decay, by wrongdoing, will suffer the penalty here, and without a thorough repentance, will not be admitted into heaven hereafter any sooner than the one who destroys life instantly. The will of God establishes the connection between cause and its effects.^{3An Appeal to Mothers, 26.}CG 444.3

Pure-minded Also Subject to Disease—We do not include all the youth who are feeble as guilty of wrong habits. There are those who are pure-minded and conscientious who are sufferers from different causes over which they have no control.^{4An Appeal to Mothers, 23.}CG 445.1

The Mental Powers Are Weakened—Fond and indulgent parents will sympathize with their children because they fancy their lessons are too great a task, and that their close application to study is ruining their health. True, it is not advisable to crowd the minds of the young with too many and too difficult studies. But, parents, have you looked no deeper into this matter than merely to adopt the idea suggested by your children? Have you not given too ready credence to the apparent reason for their indisposition? It becomes parents and guardians to look beneath the surface for the cause.^{5Testimonies For The Church 4:96, 97.}CG 445.2

The minds of some of these children are so weakened that they have but one half or one third of the brilliancy of intellect that they might have had, had they been virtuous and pure. They have thrown it away in self-abuse.^{6Testimonies For The Church 2:361.}CG 445.3

High Resolve and Spiritual Life Destroyed—Secret vice is the destroyer of high resolve, earnest endeavor, and strength of will to form a good religious character. All who have any true sense of what is embraced in being a Christian know that the followers of Christ are under obligation as His disciples to bring all their passions, their physical powers and mental faculties into perfect subordination to His will. Those who are controlled by their passions cannot be followers of Christ. They are too much devoted to the service of their master, the originator of every evil, to leave their corrupt habits and choose the service of Christ.^{7An Appeal to Mothers, 9, 10.}CG 445.4

Religion May Be Formal, but It Is Destitute—Some who profess to be followers of Christ know that they are sinning against God and ruining their health, yet they are slaves to their own corrupt passions. They feel a guilty conscience and have less and less inclination to approach God in secret prayer. They may keep up the form of religion, yet be destitute of the grace of God in the heart. They have no devotedness to His service, no trust in Him, no living to His glory, no pleasure in His ordinances, and no delight in Him.^{8An Appeal to Mothers, 25.}CG 446.1

Power of Self-government Seems Lost—Some will acknowledge the evil of sinful indulgences, yet will excuse themselves by saying that they cannot overcome their passions. This is a terrible admission for any person to make who names Christ. “Let everyone that nameth the name of Christ depart from iniquity.” Why is this weakness? It is because the animal propensities have been strengthened by exercise, until they have gained the ascendancy over the higher powers. Men and women lack principle. They are dying spiritually, because they have so long pampered their natural appetites that their power of self-government seems gone. The lower passions of their nature have taken the reins, and that which should be the governing power has become the servant of corrupt passion. The soul is held in lowest bondage. Sensuality has quenched the desire for holiness and withered spiritual prosperity.^{9Testimonies For The Church 2:348.}CG 446.2

Communication With Heaven Is Severed—Solemn messages from Heaven cannot forcibly impress the heart that is not fortified against the indulgence of this degrading vice. The sensitive nerves of the brain have lost their healthy tone by morbid excitation to gratify an unnatural desire for sensual indulgence. The brain nerves which communicate with the entire system are the only medium through which Heaven can communicate to man and affect his inmost life. Whatever disturbs the circulation of the electric currents in the nervous system lessens the strength of the vital powers, and the result is a deadening of the sensibilities of the mind. In consideration of these facts, how important that ministers and people who profess godliness should stand forth clear and untainted from this soul-debasing vice!^{10Testimonies For The Church 2:347.}CG 446.3

Some Are Remorseful, but Self-respect Is Lost—The effect of such debasing habits is not the same upon all minds. There are some children who have the moral powers largely developed, who, by associating with children that practice self-abuse, become initiated into this vice. The effect upon such will be too frequently to make them melancholy, irritable, and jealous; yet such may not lose their respect for religious worship and may not show special infidelity in regard to spiritual things. They will at times suffer keenly from feelings of remorse, and will feel degraded in their own eyes, and lose their self-respect.^{11Testimonies For The Church 2:392.}CG 447.1

The Mind May Be Fortified Against Temptation—Moral power is exceedingly weak when it comes in conflict with established habits. Impure thoughts have control of the imagination, and temptation is almost irresistible. If the mind were accustomed to contemplate elevating subjects, the imagination trained to behold pure and holy things, it would be fortified against temptation. It would linger upon the heavenly, the pure, the sacred, and could not be attracted to the base, corrupt, and vile.^{12Christian Temperance and Bible Hygiene, 135.}CG 447.2

Become Intelligent on These Things—Indulgence of the baser passions will lead very many to shut their eyes to the light, for they fear that they will see sins which they are unwilling to forsake. All may see if they will. If they choose darkness rather than light, their criminality will be none the less. Why do not men and women read and become intelligent upon these things, which so decidedly affect their physical, intellectual, and moral strength? God has given you a habitation to care for and preserve in the best condition for His service and glory. Your bodies are not your own. “What! know ye not that your body is the temple of the Holy Ghost, which is in you, which ye have of God, and ye are not your own? For ye are bought with a price; therefore glorify God in your body, and in your spirit, which are God's.” “Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you? If any man defile the temple of God, him shall God destroy; for the temple of God is holy, which temple ye are.”^{13Testimonies For The Church 2:352, 353.}CG 448.1
