We rejoice with you and give all the glory and thanks to the Lord Jesus Christ for the great improvement He has already worked in your life, and we thank Him for hearing your prayers and your tears. It is by His mercy and grace that you have seen victory, and we praise Him that you desire lasting and true freedom for the glory of God alone.
We want to gently and firmly address what you have confessed, because God calls us to holiness and purity. Pornography, masturbation, flirting with the opposite sex outside of godly courtship toward marriage, and all sexual sin is sexual immorality which God commands us to flee. As it is written, Flee sexual immorality. Every sin that a man does is outside the body, but he who commits sexual immorality sins against his own body. Or don't you know that your body is a temple of the Holy Spirit who is in you, whom you have from God. You are not your own, for you were bought with a price. Therefore glorify God in your body and in your spirit, which are God's 1 Cor 6:18-20. Jesus also taught us, everyone who gazes at a woman to lust after her has committed adultery with her already in his heart Matt 5:28. These sins begin in the heart and mind before they become actions, and that is why true deliverance must be a work of God in the heart and mind.
We are encouraged that you understand this battle is spiritual and that you are asking God to renew your mind and make you wise. Do not be conformed to this world, but be transformed by the renewing of your mind, so that you may prove what is the good, well-pleasing, and perfect will of God Rom 12:2. Lasting victory does not come by willpower alone but by walking daily by the Spirit, for Walk by the Spirit, and you won't fulfill the lust of the flesh Gal 5:16. We encourage you to continue to bring every thought into captivity to the obedience of Christ 2 Cor 10:5, to guard your eyes and your heart, to avoid places, images, conversations and relationships that stir up lust, to flee youthful passions and pursue righteousness, faith, love, and peace 2 Tim 2:22, and to stay rooted in the Word, in prayer, and in fellowship with mature believers who can hold you accountable. If you are not married, remember that God designed sexual intimacy only for the lifelong covenant of marriage between a man and a woman, and any sexual activity outside of that, including the fantasies that fuel pornography and masturbation, is fornication that dishonors Him. If you desire marriage, we pray you will pursue courtship with a fellow believer with that holy goal in mind. God promises, No temptation has taken you except what is common to man. 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 Cor 10:13. When you fall, do not remain in shame, but confess quickly, 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.
We join our faith with yours now and pray together in the name of Jesus Christ.
Father, we come before Your throne of grace in the name of Jesus Christ Your Son, and we thank You for the work You have already begun in our brother. We thank You that You have heard his crying and brought great improvement. We ask now for lasting and true deliverance for Your glory. Create in him a clean heart, O God. Renew a right spirit within him Ps 51:10. Renew his mind, wash him with Your Word, and make him very wise to discern and to hate evil and to love what is holy. Help him to do whatever it takes to remove these sins forever from his life and heart, to cut off every source of temptation, to flee when he must flee and to stand firm in the Spirit. Show him Your mercy, speak to him, give him understanding, and grant him complete deliverance. Fill him with Your Holy Spirit so that he may walk in purity, in self-control, and in joy. Guard his eyes, his thoughts, and his desires, and lead him into the freedom that Christ purchased for him. Let this testimony bring glory to You and strengthen others who struggle. We ask all of this in the mighty and saving name of Jesus Christ, our Lord, amen.
