Avoid sexual immorality: Christian guide?
How can Christians today avoid "sexual immorality" as instructed in Acts 15:20?

Our Core Verse

“Instead, we should write to them to abstain from food polluted by idols, from sexual immorality, from the meat of strangled animals, and from blood.” (Acts 15:20)


The Big Picture of Sexual Immorality

• Scripture defines sexual immorality as any sexual thought or act outside the covenant union of one man and one woman in marriage (Genesis 2:24; Matthew 19:4-5; Hebrews 13:4).

• This includes premarital sex, adultery, homosexual practice, pornography, lustful fantasizing, and all other distortions of God’s design (Matthew 5:27-28; Romans 1:26-27; 1 Corinthians 6:9-10).


Why Purity Matters

• We belong to the Lord. “You are not your own; you were bought at a price. Therefore glorify God with your body.” (1 Corinthians 6:19-20)

• Purity reflects God’s holiness. “For it is God’s will that you should be holy: You must abstain from sexual immorality.” (1 Thessalonians 4:3)

• Sexual sin uniquely damages body, soul, relationships, and witness. “He who sins sexually sins against his own body.” (1 Corinthians 6:18)


Daily Decisions That Guard the Heart

• Flee, do not linger. “Flee from sexual immorality.” (1 Corinthians 6:18)

• Say no early. “Can a man carry fire against his chest without burning his clothes?” (Proverbs 6:27-28)

• Keep a covenant with your eyes (Job 31:1) and devices: filtering software, locked settings, intentional media choices.

• Set clear physical and emotional boundaries in dating or engagement; meet in public places, end evenings early, stay accountable.


Renewing the Mind With Truth

• Saturate life with Scripture. “How can a young man keep his way pure? By guarding it according to Your word.” (Psalm 119:9)

• Meditate on what is true, honorable, right, pure, lovely, and admirable (Philippians 4:8).

• Let the Word confront fantasies; replace lustful images with passages memorized.

• Fast from media that normalizes impurity; fill downtime with edifying books, music, fellowship, service.


Walking by the Spirit

• “Walk by the Spirit, and you will not gratify the desires of the flesh.” (Galatians 5:16)

• Begin each day yielding body and mind to God (Romans 12:1-2).

• Cultivate worship, gratitude, and praise—desires shrink when the heart is satisfied in Christ.


Strength Through Community

• Pursue close friendships with believers who prize holiness (2 Timothy 2:22).

• Establish an accountability partner or small group; share victories and battles, confess promptly (James 5:16).

• Stay planted in a Bible-preaching church; serve, attend studies, and invite mentoring from older, godly saints.


Practical Boundaries That Help

• Keep electronics out of the bedroom at night.

• Limit unsupervised time alone with someone you might be attracted to.

• Treat coworkers, classmates, and friends with sibling-level honor (1 Timothy 5:1-2).

• Choose modest clothing that honors Christ and protects others.

• Guard travel: avoid hotels or trips alone when possible; if necessary, stay accountable through calls or check-ins.


When Temptation Strikes

• Quote Scripture aloud (Matthew 4:1-11 pattern).

• Physically move—leave the room, go for a walk, call a friend.

• Pray for the person you are tempted to objectify; see them as an image-bearer, not an object.

• Remember the consequences; rehearse the joy of obedience.


Restoration After Failure

• “If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.” (1 John 1:9)

• Turn immediately to Christ, not away from Him.

• Make repentance concrete—delete files, end unhealthy relationships, seek counsel.

• Receive His cleansing, then press on in renewed obedience (Philippians 3:13-14).


Conclusion: Living Set Apart

God never commands without enabling. By His Word, His Spirit, and the support of His people, believers today can obey Acts 15:20 and shine in a culture darkened by sexual confusion. Purity glorifies the Savior, strengthens the church, and proclaims a better story to the watching world.

Why did the apostles emphasize abstaining from 'things polluted by idols' in Acts 15:20?
