“Masturbation – is it a sin according to the Bible?”The Bible never explicitly mentions masturbation or states whether or not masturbation is a sin. The Scripture most frequently pointed to in regards to masturbation is the story of OnanGenesis 38:9-10But Onan was not willing to have a child who would not be his own heir. So whenever he had intercourse with his brother’s wife, he spilled the semen on the ground. This prevented her from having a child who would belong to his brother. But the Lord considered it evil for Onan to deny a child to his dead brother. So the Lord took Onan’s life, too.Some interpret this passage as saying that “spilling your seed” on the ground is a sin. However, that is not precisely what the passage is saying. God condemned Onan not for “spilling his seed” but because Onan refused to fulfill his duty to provide an heir for his brother.The passage is not about masturbation, but rather about fulfilling a family duty. A second passage sometimes used as evidence for masturbation’s being a sin isMatthew 5:27-30 “You have heard the commandment that says, ‘You must not commit adultery.’ But I say, anyone who even looks at a woman with lust has already committed adultery with her in his heart. So if your eye—even your good eye—causes you to lust, gouge it out and throw it away. It is better for you to lose one part of your body than for your whole body to be thrown into hell. And if your hand—even your stronger hand—causes you to sin, cut it off and throw it away. It is better for you to lose one part of your body than for your whole body to be thrown into hell.Jesus speaks against having lustful thoughts and then says, “If your right hand causes you to sin, cut it off and throw it away.” While there are parallels between this passage and masturbation, it is unlikely that masturbation was what Jesus was alluding to.While the Bible nowhere explicitly states that masturbation is a sin, there is no question as to whether the actions that lead to masturbation are sinful. Masturbation is nearly always the result of lustful thoughts, sexual stimulation, and/or pornographic images. It is these problems that need to be dealt with. If the sins of lust, immoral thoughts, and pornography are forsaken and overcome, masturbation will become a non-issue. Many people struggle with guilty feelings concerning masturbation, when in reality, the things that led to the act are far more worthy of repentance.Some biblical principles can be applied to the issue of masturbation.Ephesians 5:3Let there be no sexual immorality, impurity, or greed among you. Such sins have no place among God’s people.It is hard to see how masturbating can pass that particular test. The Bible teaches us1 Corinthians 10:31So whether you eat or drink, or whatever you do, do it all for the glory of God.If you cannot give God glory for something, you should not do it.If a person is not fully convinced that an activity is pleasing to God, then it is a sin:Romans 14:23But if you have doubts about whether or not you should eat something, you are sinning if you go ahead and do it. For you are not following your convictions. If you do anything you believe is not right, you are sinning.Further, we need to remember that our bodies have been redeemed and belong to God. 1 Corinthians 6:19-20Don’t you realize that your body is the temple of the Holy Spirit, who lives in you and was given to you by God? You do not belong to yourself,for God bought you with a high price. So you must honor God with your body.This great truth should have a real bearing on what we do with our bodies. In light of these principles, the conclusion that masturbation is a sin is biblical. Clearly, masturbation is:Not glorifying to GodDoes not avoid the appearance of immoralityNor does it pass the test of God’s having ownership over our bodies.
