Lesson 34: How to Flee Fornication and Keep Your Body Pure
God cares what you do with your body.
The body is not separate from discipleship.
It is not outside God’s authority.
It is not a private possession that may be surrendered to any desire as long as other people do not know.
Scripture says:
“Flee fornication.
Every sin that a man doeth is without the body;
but he that committeth fornication sinneth against his own body.
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.”
— 1 Corinthians 6:18–20, KJV
These words establish the foundation:
Flee fornication.
You are not your own.
You were bought with a price.
Glorify God in your body.
Sexual purity is not merely an attempt to avoid embarrassment, disease, broken relationships, or earthly consequences.
It is bodily faithfulness to Jesus Christ.
What Is Fornication?
The word fornication refers broadly to sexual immorality.
It includes sexual conduct outside the boundaries God established for marriage.
Scripture does not allow society, desire, emotion, or mutual agreement to redefine those boundaries.
God created the body.
God created marriage.
God established the rightful covenant for sexual union.
Hebrews says:
“Marriage is honourable in all, and the bed undefiled:
but whoremongers and adulterers God will judge.”
— Hebrews 13:4, KJV
The Bible does not teach that the body is evil.
It does not teach that marriage is shameful.
It calls marriage honorable and the marriage bed undefiled.
What God condemns is the removal of sexual conduct from the covenant in which He placed it.
The issue is not whether two people possess strong feelings.
The issue is whether the relationship honors what God has established.
The Body Is for the Lord
Paul writes:
“…Now the body is not for fornication, but for the Lord;
and the Lord for the body.”
— 1 Corinthians 6:13, KJV
The body has a purpose.
It is for the Lord.
That means your body is not finally for:
uncontrolled appetite;
self-expression without divine boundaries;
the approval of another person;
temporary pleasure;
secret uncleanness;
or any relationship that requires disobedience.
The body is for the Lord.
When temptation speaks, remember:
“My body belongs to Jesus Christ.”
That statement does not mean temptation will immediately disappear.
It restores the question of ownership.
The body is not an independent object deciding what will provide the greatest immediate pleasure.
It belongs to a Master.
You Are Not Your Own
Modern culture often treats personal desire as sufficient authority.
It says:
“My body belongs to me, so I alone decide what is right.”
Scripture tells the believer:
“…ye are not your own?”
— 1 Corinthians 6:19, KJV
The Christian has been redeemed.
He belongs to Jesus Christ.
This does not reduce his dignity. It establishes his highest dignity and purpose.
His body is not meaningless matter.
It has been claimed by the Lord.
It is to become an instrument of obedience, worship, service, labor, compassion, and righteousness.
The believer should not ask only:
“What do I want to do with my body?”
He should ask:
“What honors the One to whom my body belongs?”
You Were Bought With a Price
Scripture says:
“For ye are bought with a price…”
— 1 Corinthians 6:20, KJV
Jesus Christ did not redeem His people so that they could remain under the unquestioned rule of sinful appetite.
The price of redemption should make purity precious.
Sexual temptation often attempts to shrink the moment.
It wants the believer to think only about immediate desire.
The cross enlarges the view.
Christ gave Himself.
The believer belongs to Him.
The body should not be taken into conduct that dishonors the One who purchased it.
When temptation says, “This moment is all that matters,” remember the price.
You were not bought so that the remainder of your brief earthly life could be spent building patterns that will bring shame before God and have no eternal value.
You were bought to glorify Him.
The Believer’s Body Is Joined to Christ
Paul asks:
“Know ye not that your bodies are the members of Christ?
shall I then take the members of Christ, and make them the members of an harlot?
God forbid.”
— 1 Corinthians 6:15, KJV
The body is not disconnected from the believer’s relationship with Christ.
Paul does not permit the Christian to say:
“My soul belongs to Jesus, but my body is my private concern.”
The believer’s body is described as belonging to Christ.
Sexual conduct therefore has spiritual significance.
Paul continues:
“But he that is joined unto the Lord is one spirit.”
— 1 Corinthians 6:17, KJV
The believer is joined to the Lord.
That union should govern every lesser desire and relationship.
Ask:
“How can I use what belongs to Christ in a way that dishonors Christ?”
The answer should not be casual.
God’s Will Is Sexual Purity
Many people ask:
“What is God’s will for my life?”
Scripture gives at least one unmistakable answer:
“For this is the will of God, even your sanctification,
that ye should abstain from fornication:
That every one of you should know how to possess his vessel
in sanctification and honour;
Not in the lust of concupiscence,
even as the Gentiles which know not God:”
— 1 Thessalonians 4:3–5, KJV
God’s will is sanctification.
God’s will is abstaining from fornication.
God’s will is possessing the body in holiness and honor.
The question is not unclear.
If a relationship requires sexual immorality, that conduct is not God’s will.
If someone tells you that God brought you together while pressuring you to violate what God commanded, the claim contradicts Scripture.
God does not guide His people by leading them against His revealed will.
Purity Is Not Merely Avoiding the Final Act
A person may attempt to remain technically outside a final sinful act while repeatedly choosing everything that moves toward it.
He keeps the secret relationship.
Continues the suggestive communication.
Creates private opportunities.
Allows physical boundaries to move gradually.
Returns to situations where restraint is repeatedly weakened.
Then he claims that he is still trying to remain pure.
But fleeing fornication means refusing the path that leads toward it.
Proverbs gives practical instruction:
“Remove thy way far from her,
and come not nigh the door of her house:”
— Proverbs 5:8, KJV
Not merely:
“Do not enter.”
But:
“Come not nigh the door.”
Wisdom recognizes that distance from the doorway is safer than attempting to prove strength while standing at it.
Flee Means Leave
The command is not:
“Study fornication.”
“Become confident around it.”
“See how close you can remain.”
“Continue talking until the temptation feels satisfied.”
The command is:
Flee.
Fleeing is physical and decisive.
It may require:
leaving a place;
ending a private conversation;
refusing a meeting;
stopping a relationship;
changing a routine;
blocking communication;
removing access;
or calling someone for immediate help.
Fleeing does not mean you are spiritually weak.
It means you believe God’s command more than you believe your own ability to remain near danger.
Pride says:
“I can handle this.”
Wisdom says:
“God told me to flee.”
Joseph Did Not Negotiate
Joseph provides one of Scripture’s clearest examples.
When Potiphar’s wife tempted him, he answered:
“…how then can I do this great wickedness,
and sin against God?”
— Genesis 39:9, KJV
Joseph viewed the temptation correctly.
It was not merely an opportunity that might damage his reputation.
It was wickedness.
It was sin against God.
When she later caught him by his garment, Scripture says:
“And he left his garment in her hand, and fled, and got him out.”
— Genesis 39:12, KJV
Joseph did not remain to continue explaining.
He did not attempt to recover his garment first.
He did not prove that he could resist while staying within reach.
He fled.
Sometimes obedience means accepting an immediate inconvenience, loss, misunderstanding, or embarrassment in order to leave sin behind.
Better to leave the garment than lose purity.
Do Not Confuse Attention With Love
Sexual temptation often presents itself through the language of love.
Someone may say:
“If you loved me, you would do this.”
“Because our feelings are genuine, the boundary should not apply.”
“No one understands our relationship.”
“We plan to marry eventually.”
But true love does not ask another person to sin against God.
It does not use another person’s body to satisfy desire.
It does not awaken or intensify what cannot yet be expressed righteously.
It does not make secrecy necessary.
It does not disregard conscience and eternity.
A person who pressures you toward fornication is not protecting your soul.
And if you pressure another person, you are not loving that person biblically.
Love should help another person remain faithful to God.
Sexual Sin Is Not Merely Private
Sexual sin often claims:
“This affects only us.”
But it reaches farther.
It affects the sinner’s own body and conscience.
It may wrong a present or future spouse.
It may damage another person’s relationship with God.
It may create secrecy, distrust, shame, or divided loyalty.
It may harm families and church communities.
In the context of sexual purity, Paul warns:
“That no man go beyond and defraud his brother in any matter:
because that the Lord is the avenger of all such…”
— 1 Thessalonians 4:6, KJV
Another person is not an object through which desire may be satisfied.
That person bears God’s image.
Sexual sin does not become righteous merely because both people agree to participate.
Human consent cannot overturn God’s authority.
Do Not Yield Your Body as an Instrument of Sin
Paul writes:
“Neither yield ye your members as instruments of unrighteousness unto sin:
but yield yourselves unto God…
and your members as instruments of righteousness unto God.”
— Romans 6:13, KJV
The body may be yielded.
Hands, feet, speech, strength, and physical presence may become instruments through which either righteousness or sin is carried out.
The believer is instructed to yield himself to God.
Sexual purity is therefore not only saying no to fornication.
It is saying yes to the rightful use of the body.
Use your strength to serve.
Use your presence to encourage.
Use your hands for honest labor.
Use your body in worship, faithfulness, kindness, and obedience.
The body should not remain empty territory after temptation is refused.
Yield it positively unto God.
Remove the Opportunity Before Desire Becomes Strong
Fleeing is often most effective before temptation reaches its greatest intensity.
Do not wait until you are alone, emotionally involved, physically close, and unwilling to leave.
Establish distance earlier.
Ask:
Where does the temptation gain access?
Through a particular person?
A private place?
A communication channel?
Late-night conversations?
Travel arrangements?
An unlocked device?
An unnecessary meeting?
A relationship that increasingly depends upon secrecy?
Identify the access point.
Then take action while judgment is clear.
The full teaching on guarding the eyes and thoughts belongs to Lesson 35. The responsibility here is physical opportunity:
Do not repeatedly place your body where obedience becomes increasingly difficult.
Do Not Keep a Secret Door Open
A person may publicly reject sexual sin while privately preserving access to it.
He keeps the number.
The hidden account.
The private conversation.
The opportunity to return.
The explanation that makes secrecy seem reasonable.
He says that he wants freedom while protecting the doorway to bondage.
That is not fleeing.
Fleeing closes the route by which the sin is repeatedly approached.
You may need to do something that feels severe.
But the apparent severity of the action should be compared with the seriousness of the danger.
Do not preserve the means of returning to what you claim to have left.
Flee and Follow
Paul tells Timothy:
“Flee also youthful lusts:
but follow righteousness, faith, charity, peace,
with them that call on the Lord out of a pure heart.”
— 2 Timothy 2:22, KJV
The command contains both movement away and movement toward.
Flee lusts.
Follow righteousness.
Follow faith.
Follow charity.
Follow peace.
And do so with people who call upon the Lord from a pure heart.
Purity cannot be maintained merely by staring continually at what you are trying not to do.
Fill the life with what belongs to God.
Pursue righteous service.
Strengthen healthy fellowship.
Use time faithfully.
Keep the body occupied with honorable work.
Do not merely run away from impurity.
Run toward a life that leaves less room for it.
Do Not Attempt to Fight Alone in Secrecy
Sexual sin often grows through secrecy.
A person may fear embarrassment so deeply that he continues hiding until the problem becomes more established.
Seeking help does not require broadcasting private struggles to everyone.
It means bringing the matter to a mature, trustworthy, biblically faithful person who can pray, ask honest questions, and help remove secrecy.
Choose help carefully.
The person should not encourage compromise, spread personal information carelessly, or become another source of temptation.
Pride says:
“No one must ever know that I am struggling.”
Humility says:
“I would rather expose the danger appropriately than allow secrecy to strengthen it.”
The later lessons on fellowship and leadership will explore these relationships more fully.
The present truth is simple:
Do not protect sexual sin with isolation.
Purity Is Not Hatred of the Body
Biblical purity is sometimes misrepresented as shame about the body.
But God created the body.
The body can glorify Him.
Marriage is honorable.
Affection within God’s covenant is not unclean.
Purity does not mean hating men or women.
It does not mean pretending sexual desire does not exist.
It does not mean treating marriage as spiritually inferior.
Purity means receiving God’s design rather than using the body against it.
Sin abuses what God made.
Holiness restores it to its proper purpose.
The body should not be despised.
It should be honored as belonging to the Lord.
Purity Is Not Self-Righteousness
A person who has remained outwardly pure has no reason to boast over someone who has fallen.
Every believer depends upon grace.
Pride itself is sin.
The pure person should remain watchful, humble, and compassionate.
He should never think:
“I could never fall.”
Neither should someone who has sinned conclude:
“I am permanently dirty and can never walk in purity.”
Jesus Christ receives repentant sinners.
Past sin may carry real consequences, but it does not place a repentant person beyond mercy.
Purity is not a ground for self-exaltation.
It is a life of gratitude and submission before God.
When You Have Already Fallen
Some readers may already have committed sexual sin.
The answer is not denial.
Not renaming.
Not hiding.
Not continuing because the past cannot be changed.
Scripture says:
“He that covereth his sins shall not prosper:
but whoso confesseth and forsaketh them shall have mercy.”
— Proverbs 28:13, KJV
Confess.
Forsake.
Receive mercy through Jesus Christ.
Where another person has been wronged, appropriate truth and responsibility may also be necessary.
Lesson 18 has already explained confession and return in detail.
The emphasis here is that repentance must include leaving the sexual sin.
Do not use past failure as permission for present continuation.
Mercy calls you out of hiding and back into the light.
Keep Cleansing Body and Spirit
Paul writes:
“Having therefore these promises, dearly beloved,
let us cleanse ourselves from all filthiness of the flesh and spirit,
perfecting holiness in the fear of God.”
— 2 Corinthians 7:1, KJV
Purity concerns the flesh and spirit.
This lesson concentrates primarily upon bodily conduct and physical opportunity.
Lesson 35 will address the eyes and thoughts more directly.
Both belong beneath God’s authority.
Do not maintain an outward boundary while inwardly feeding what will eventually press toward expression.
Neither claim inward sincerity while allowing bodily conduct to violate God’s command.
God calls the whole person into holiness.
A Practical Fleeing Plan
Use this process with one actual danger.
1. Name the Sin Honestly
Do not soften fornication into “a complicated relationship” or “a private weakness.”
2. Identify the Physical Access Point
What person, place, routine, device, meeting, or communication makes the sin easier?
3. Create Distance
Move far from the doorway rather than standing beside it.
4. Leave Immediately When Pressure Begins
Do not remain to prove strength.
5. Close the Secret Door
Remove the means by which you repeatedly return.
6. Seek Trustworthy Help
Bring hidden danger into appropriate light.
7. Follow Righteousness
Replace the empty space with honorable service, responsibility, fellowship, and worship.
8. Remember Ownership
Your body belongs to Jesus Christ.
9. Return Honestly After Failure
Confess and forsake rather than hiding or continuing.
Discipleship Questions
- Why does Scripture say the believer’s body is for the Lord rather than for fornication?
- What does the example of Joseph teach about the practical meaning of fleeing?
- Why is remaining near sexual temptation an expression of pride rather than strength?
- How can sexual sin wrong more people than the two directly involved?
- What physical access point, opportunity, or secret door must you remove in order to obey God?
Closing Exhortation
Flee fornication.
Do not negotiate with it.
Do not remain near it to prove your strength.
Do not call it love when it requires disobedience.
Do not call it private when God sees and other lives may be affected.
Do not treat the body as though it belongs only to you.
Your body is for the Lord.
You are not your own.
You were bought with a price.
You are joined unto Christ.
Therefore, glorify God in your body.
Remove your way far from temptation.
Leave when pressure begins.
Close the secret door.
Seek help rather than hiding.
Follow righteousness.
And where there has been failure, confess and forsake it.
The pleasure offered by sin is brief.
The consequences may reach far beyond the moment.
Your earthly life is also brief. Do not spend it surrendering what belongs to Christ to something that will produce shame and possess no eternal value.
Keep your body for the Lord.
A Prayer for Sexual Purity
Father,
Thank You for creating my body and redeeming me through Jesus Christ.
Forgive me for every way I have treated my body as though it belonged only to me.
Your Word says that the body is not for fornication, but for the Lord.
Help me believe and obey that truth.
Show me every relationship, opportunity, place, routine, or secret door that is drawing me toward sexual sin.
Give me courage to leave rather than negotiate.
Keep me from trusting myself near temptation.
Teach me from Joseph’s example to recognize sexual sin as sin against You and to flee immediately.
Help me honor marriage and refuse to use another person’s body for sin.
Keep me from calling lust love or secrecy freedom.
Where I have sinned, bring me to honest confession, true forsaking, and mercy through Jesus Christ.
Give me humility to seek trustworthy help when needed.
Teach me to possess my body in sanctification and honor.
Let my hands, strength, time, and physical life become instruments of righteousness unto You.
I am not my own.
I was bought with a price.
Help me glorify You in my body and in my spirit.
In Jesus’ name, amen.
