God's Battle Plan for Purity Series: Strategy One: Know Our Battle

Strategy One: Know Our Battle

In order to win the battle for purity, believers must first answer this question, “What is sexual immorality?” If we are going to avoid it and flee from it, we must know what it is. I think many Christians are failing simply because they don’t know what sexual immorality is. It has never been defined for them. Some would even say that it is just “intercourse.”

Many believe that oral sex, anal sex, masturbation, heavy petting, etc., are not part of sexual immorality. Therefore, they open these doors as avenues of fulfilling their lust while trying to maintain their “virginity.”

However, by doing this, they are really committing sexual immorality and opening the door for the enemy to attack them and bring them under greater sexual bondage. Therefore, this is an important question to answer. What is sexual immorality?

In order to answer this question, let’s consider 1 Corinthians 7:1-3,

Now for the matters you wrote about: It is good for a man not to marry. But since there is so much immorality, each man should have his own wife, and each woman her own husband. The husband should fulfill his marital duty to his wife, and likewise the wife to her husband.

Paul, the author, said that it is good for a man to stay single and not marry. But because of temptation towards sexual immorality, each person should consider marriage as a spiritual protection. In marriage, the husband and the wife fulfill each other sexual desires.

From this, we can gain this basic definition of sexual immorality: Sexual immorality is the attempt to fulfill the natural sexual desires that God gave humanity outside of the marriage union. This includes things like sex, oral sex, anal sex, masturbation, heavy petting, pornography, and sexual imaginations. In short, sexual immorality encompasses all acts and thoughts designed to fulfill sexual desire outside of marriage.

In fact, Jesus said this about sexual immorality in Matthew 5:27-28: “‘You have heard that it was said, ‘Do not commit adultery.’ But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart.”

He said that if person lusted, he had already committed adultery. This person went outside of the marriage union to fulfill sexual desires and, therefore, committed sexual immorality.

This might seem unrealistic to some. “How can anyone keep themselves from sexual thoughts?” and some might ask, “Why would they?” However, the reality is that God created sex and he has given us ethics for its use. If we pursue these desires outside the marriage union, we do it at our own peril. We sin against our own bodies.

How then should a single person respond to his natural desires? Scripture uses the analogy of sleeping for those desires. Listen to what Solomon’s fiancée said in the Song of Solomon: “Daughters of Jerusalem, I charge you by the gazelles and by the does of the field: Do not arouse or awaken love until it so desires” (3:5). She exhorts the young ladies in Jerusalem to keep their desires asleep until it is time.

Well, the next question, we must ask is, “How can we keep those desires asleep?” or “How can we put them back to sleep after they have been awaken?” We will consider this in the following strategies.


  • What is a definition for sexual immorality? Why is it important to know the definition?

  • How commonly do you think people open sexual doors simply because of lack of truly understanding the definition?

  • Why is it important to keep sexual desires asleep?

  • When should churches and parents start instructing children about sexual immorality?

  • What other questions or thoughts did you have about the section?

  • What ways can you pray in response? Take a second to pray as the Lord leads.
