What is sexual immorality?

The times we live in are those in which the true values are inverted or even perverted. Their meaning is distorted from good into evil. After a 70 years period of socialism and atheism people do not longer make the difference between good and evil. That’s why, it is necessary to define these values again. So, what is sexual immorality? Some say that immoral is only when you are unfaithful to your partner of marriage. In this article I want to make a larger presentation of what God defines in the Bible as sexual immorality.


Adultery is every sexual act where at least one of the implied persons are a part of the covenant of marriage. God is very categorical in regards to this sin and He says in the 10 commandments:

You shall not commit adultery. (Exodus 20:14)(NASB)

This was such a grave sin that it had to be punished with death, as the following passage says:

If there is a man who commits adultery with another man’s wife, one who commits adultery with his friend’s wife, the adulterer and the adulteress shall surely be put to death. (Leviticus 20:10)(NASB)


Fornication is the sexual act where only unmarried persons are involved. Today, a very wrong opinion is spread that it is sin only to change your partner, but if you are unmarried, you are free to have sexual relations with the person you like. Even some girls, that have decided to be virgins until marriage, are mocked by the other girls around them. Fornication is a sin as grave as adultery because it affects gravely the future marriage and the eternal fate of that person. The Bible writes in this sense:

Marriage is to be held in honor among all, and the marriage bed is to be undefiled; for fornicators and adulterers God will judge. (Hebrews 13:4)(NASB)

According to the cited biblical verse, those who commit adultery defile trough this their future marriage and the marriage bed, that is their sexual relation. No one will be able to rejoice of a defiled sexual relation, but it will transform his/her future wife or husband in an unguilty victim. That’s why, if you are a man, it is important to propose marriage to a virgin and a righteous girl, and if you are a girl, to get married to a man, who didn’t live immorally. It is true that such kind of men are fewer, but they still exist. I was very glad and I praised the Lord when I heard the statement the Brazilian footballer made to journalists, that he had been virgin before his marriage and he hadn’t ever had any sexual relations with another woman. This is a real MAN and a powerful Christian, that wasn’t defeated by the pressure of the time or of the thinking, that is “in fashion”. Follow up his example! Hold your future marriage and your marriage bed undefiled.

Sexual perversions

These are a great evil and in our world the immoral people try to present them as something normal, calling them “untraditional sexual orientation”. God calls them in the Bible “abominations” and “ defiled things” and He gives a list of them. Here is the list:

None of you shall approach any blood relative of his to uncover nakedness; I am the LORD. (Leviticus 18:6)(NASB)

In continuation, the text defines clearly who are considered blood relatives, with which the marriage is banned. These are the parents, the step parents, the sister, the brother, the nephew, the niece, the aunt, the sister of the brother, the aunt from the uncle, the daughter-in-law, etc. All these sexual relations are incest. After that, the list continues with other things that are defined as perversions:

You shall not lie with a male as one lies with a female; it is an abomination. Also you shall not have intercourse with any animal to be defiled with it, nor shall any woman stand before an animal to mate with it; it is a perversion. Do not defile yourselves by any of these things; for by all these the nations which I am casting out before you have become defiled. (Leveticus 18:22–24)(NASB)

Immorality of the mind

This is another way of immorality that is very spread and when a man begins to practice such kind of immorality, he will necessarily start to practice some of them or maybe all of those written above. What does immorality of the mind mean? Lord Jesus defines it in this way:

But I say to you that everyone who looks at a woman with lust for her has already committed adultery with her in his heart. (Matthew 5:28)(NASB)

The sinful nature provokes every man to lust sexually another woman than the one that is his wife. But, every man is responsible to learn to control his mind and his eyes, because who looks at a woman with lust has already committed adultery with her in his heart, and the adultery committed in the heart is equivalent to the one committed physically, because it will finally lead you to physical immorality of all kinds. That’s why, it is important to learn to control your thoughts and your eyes. The righteous Job said in regards to this:

I have made a covenant with my eyes; how then could I gaze at a virgin? (Job 31:1)(NASB)

Today, people led by the wickedness of their heart, have developed a whole industry of pornography. A very great part of Internet pages contain pornography. “Playboy” magazine, that is one with an immoral content and that spreads much immorality in the world, has 15 million readers and is one of the most read magazine in the world. If these people only realized how much evil they had brought in the their lives and families through this magazine, they wouldn’t have bought it. Unfortunately, when they realize this evil, it is too late, because their own lives and their own families have already been destroyed.
All these practices that have been listed above are sexual immorality that brings very many grave consequences unto people’s lives. Tomorrow I will publish an article about the Archangels Michael and Gabriel and in a day I will come with another article where I will touch the subject “How to protect yourself of the pressure of sexual immorality that is around?”
