We rejoice with you and we give all the glory and thanks to the Lord Jesus Christ for the great improvement He has already worked in your life, for it is God who works in you both to will and to work for His good pleasure, Philippians 2:13. We have heard your tears and your earnest prayers and we join you now in crying out for lasting and true deliverance and complete freedom, for the glory of God.
We know that these sins you have named, pornography, masturbation, flirting outside of godly courtship, and all sexual sin, are indeed sin before a holy God and must be forsaken. The Scripture is clear that we are to flee sexual immorality, for every sin that a man does is outside the body, but he who commits sexual immorality sins against his own body, 1 Corinthians 6:18. Jesus taught us that everyone who gazes at a woman to lust after her has committed adultery with her already in his heart, Matthew 5:28. Masturbation and pornography feed that lust of the flesh and defile the heart and the body which is meant to be a temple of the Holy Spirit, 1 Corinthians 6:19-20. Flirting with the opposite sex when it is not with the purpose of seeking a godly spouse in marriage dishonors God and can lead others into temptation as well. We must rebuke these things as sin and turn from them completely, not making provision for the flesh, Romans 13:14.
Yet we also rejoice that you have come in repentance, for if we confess our sins, He is faithful and righteous to forgive us the sins and to cleanse us from all unrighteousness, 1 John 1:9. Godly sorrow works repentance to salvation, 2 Corinthians 7:10, and your tears are not unseen by your Father who shows mercy to those who humble themselves before Him.
We encourage you to walk in the practical wisdom God provides for renewal and lasting victory. Do not be conformed to this world, but be transformed by the renewing of your mind, Romans 12:2. This renewal comes by daily filling your mind with the Word of God, by thinking on whatever things are true, whatever things are honorable, whatever things are pure, Philippians 4:8, and by walking by the Spirit so that you will not fulfill the lust of the flesh, Galatians 5:16. We encourage you to make a covenant with your eyes as Job did, Job 31:1, to cut off every source of temptation, to flee youthful lusts and pursue righteousness, faith, love, and peace, 2 Timothy 2:22, and to bring your struggle into the light with a mature, trusted Christian brother for accountability, for we are to confess our sins to one another and pray for one another that we may be healed, James 5:16. No temptation has taken you except what is common to man, but God is faithful, who will not allow you to be tempted above what you are able, but will with the temptation also make the way of escape, that you may be able to endure it, 1 Corinthians 10:13.
We pray together for you now.
Father in heaven, we come before Your throne of grace in the mighty name of Jesus Christ, our only Savior and our only access to You. We thank You for the mercy You have already shown to our brother and for the improvement You have begun. We ask You to complete the good work You have started, Philippians 1:6, and to make it lasting and true for Your glory. Create in him a clean heart, O God, and renew a right spirit within him, Psalm 51:10. Renew his mind, make him very wise with the wisdom that comes from above, James 1:5, so that he may discern and hate every evil way and love what is holy. Teach him to take every thought captive to the obedience of Christ, 2 Corinthians 10:5, and do not let sin reign in his mortal body that he should obey its lusts, Romans 6:12. Deliver him completely, speak to him, give him understanding, and keep these sins forever far from him. Fill him with Your Holy Spirit, with a love for Your Word and for prayer, and with a desire for purity that honors marriage as You designed it between one man and one woman. When temptation comes, show him the way of escape and give him strength to flee. Let him walk in freedom and in the joy of forgiveness, knowing that there is now no condemnation for those who are in Christ Jesus, Romans 8:1. We ask all of this in the name of Jesus Christ, Amen.
