We understand your struggle and we are here to lift you up in prayer and provide biblical guidance. First, let's address the sin of fornication that you've fallen into. We are clearly told in scripture, 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 Corinthians 6:18-20 WEB.
Although you fell into this sin, remember that God is merciful and ready to forgive. 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 WEB. God is faithful. God has not changed his mind about you. Now, we need to take authority over this. We need to cast out the spirit of lust and fornication in the name of Jesus Christ. Then, we need to ask for and believe by faith that God will restore your peace and joy.
Let's pray together:
Dear Heavenly Father,
We come before You in the name of Jesus Christ, confessing the sin of fornication. We repent for this sin and ask for Your forgiveness. We rebuke the enemy of our souls and stand against the powers of darkness in Jesus's name. We break the power of lust and fornication in Jesus Christ. God, we ask you to forgive and cleanse from your presence all sexual sin and restore peace, joy, and righteousness. We know that there is therefore now no condemnation to those who are in Christ Jesus, who don't walk according to the flesh, but according to the Spirit. Romans 8:1 WEB. For the law of the Spirit of life in Christ Jesus made me free from the law of sin and of death. Romans 8:2 WEB. Father we pray that you would restore a steadfast spirit within, and give grace to stand against this temptation in the future. We ask for God's will to be done in this person's life.
God is faithful and just to forgive. He has not turned his back. He will not take the Holy Spirit from you, and he will not take the Holy Spirit from us. God does not show favoritism against us, for we are all one in Christ Jesus. And in Jesus Christ, you are forgiven. But we must remain sober and alert, for our adversary the devil prowls around like a roaring lion, seeking someone to devour. But resist him, firm in your faith, knowing that the same experiences of suffering are being accomplished by your brotherhood in the world. 1 Peter 5:8-9 WEB. So, we must put on the full armor of God that we may be able to stand against the wiles of the devil. For our struggle is not against flesh and blood, but against the rulers, against the powers, against the world forces of this darkness, against the spiritual forces of wickedness in the heavenly places. Ephesians 6:11-12 WEB.
It is only through Jesus that this person can be saved. For there is no other name given among men, whereby we must be saved. Acts 4:12 WEB. Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved. Acts 4:12 WEB. For whoever will call on the name of the Lord will be saved. Romans 10:13 WEB. Believe in the Lord Jesus Christ, and you shall be saved. Acts 16:31 WEB. And it shall be that whoever shall call on the name of the Lord shall be saved. Acts 2:21 WEB. For whoever will call on the name of the Lord will be saved. Romans 10:13 WEB. By the name of Jesus, every knee will bow and every tongue confess that Jesus Christ is Lord in heaven and on earth and under the earth. Philippians 2:10 WEB. That at the name of Jesus every knee should bow, of things in heaven and things on earth and things under the earth, Philippians 2:10 WEB. We cast out every spirit that would not bow its knee to the name of Jesus, in Jesus' name we pray. We take authority over every spirit that lifts itself up against the knowledge of God, in Jesus' name we pray. We cast out every spirit that would not confess that Jesus Christ is Lord, in Jesus' name we pray. We cast out every spirit that would not confess that Jesus Christ came in the flesh, in Jesus' name we pray. We cast out every spirit that would not confess that Jesus Christ is the Son of God, in Jesus' name we pray. We cast out every spirit that would not confess that Jesus Christ is the way, the truth, and the life, in Jesus' name we pray. We cast out every spirit that would not confess that Jesus Christ is the only way to the Father, in Jesus' name we pray. We cast out every spirit that would not confess that Jesus Christ is the only way to eternal life, in Jesus' name we pray.
Prayer Focus: God, Thank You for loving me. God, I ask You in Jesus’ name please bless me with everything that I stand in need of and everything You want me to have.
