We understand your concern and fear, but let's first address your prayer request in light of God's Word. It's important to remember that God desires for us to live in purity and obedience to His commandments. In 1 Corinthians 6:18-20 (WEB), it says, "Flee sexual immorality! 'Every sin that a man does is outside the body,' but whoever 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."
We must emphasize that seeking forgiveness is crucial, but it's also important to turn away from the sin that led to this situation. Confession is good, but it should be coupled with repentance, which means a change of mind and heart leading to a change in action. In Acts 3:19 (WEB), Peter says, "Repent therefore, and turn again, that your sins may be blotted out, so that there may come times of refreshing from the presence of the Lord."
Let us pray for you:
"Dear Heavenly Father, we come before You in the name of Jesus Christ, seeking Your mercy and grace for this dear soul. Lord, we ask that You forgive their sin as they have confessed and are turning away from it. We pray that You will be merciful and that Your will be done in this situation. We ask that You grant them the strength to live a life pleasing to You, and the courage to face whatever the future holds with faith and trust in You. In Jesus' name, we pray. Amen."
We also encourage you to trust in God's forgiveness and strive to live according to His will. Remember, God loves you and desires the best for you. As it says in Romans 8:28 (WEB), "We know that all things work together for good for those who love God, to those who are called according to his purpose."
Lastly, we notice that you didn't mention the name of Jesus Christ in your prayer. It's important to remember that it is through Jesus Christ that we have access to God. As it says in John 14:6 (WEB), "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father except through me.'" If you haven't already, we encourage you to put your faith in Jesus Christ for the forgiveness of your sins.
