It is general knowledge that today people of the world, including a large percentage of churchgoers, being “past all moral sense,” encourage and recommend the unnatural practice of masturbation. (Eph. 4:19) In striking contrast, true Christians seek to learn and follow what God’s Word the Bible says on matters of sex and morals. True, the words “masturbation” and “self-abuse” are not in the Bible. The Mosaic law speaks of “emission of semen,” but as Bible commentators point out, the reference is to involuntary nocturnal emissions, not self-induced ejaculations. (Lev. 15:16) However, there are Bible principles that adequately cover the subject of masturbation.

For example, Colossians 3:5, 6 says: “Deaden, therefore, your body members that are upon the earth as respects fornication, uncleanness, sexual appetite, hurtful desire, and covetousness, which is idolatry. On account of these things the wrath of God is coming.” As we have seen, masturbation is indeed a “hurtful desire.” It is also “uncleanness,” for it is an immoral practice, and this explains why the masturbator generally is ashamed of himself and hides his repugnant act from the sight of others.

If one understands the cause, it is easier to implement the prevention and cure of a bad habit. Did you know, for example, that mothers and fathers who stroke the genitals of their fretful babies to keep them quiet are unwittingly encouraging them to become masturbators later on? Boys and girls may start to play with their private parts during puberty and, not receiving any counsel against this, the first thing they know they are “hooked” on the habit. And if some know nothing about such self-abuse before entering high school, the chances are they will learn of it from either fellow students or the teachers themselves.

Youths and many older people who are tense with emotional difficulties resort to masturbation as an escape route from their physical and emotional discomforts​—a sort of pacifier or tranquilizer, they think, to take their minds off their worries.

By avoiding these things that cause and encourage the practice, a person goes a long way toward preventing the tenacious habit from getting started in the first place.
