We understand your concern and urgency in this situation, but we must address this in a biblically sound manner. The Bible is clear about sexual relationships, stating, "Marriage is to be held in honor among all, and the bed undefiled: but God will judge the sexually immoral and adulterers" (Hebrews 13:4, WEB). Having unprotected sex outside of marriage is considered fornication, which is against God's will.
Firstly, we need to pray for God's mercy and forgiveness. Let's pray together:
"Dear Heavenly Father, we come before you in the name of Jesus Christ, seeking your mercy and forgiveness for our sister who has fallen into sin. We know that your grace is sufficient for us, and your power is made perfect in weakness (2 Corinthians 12:9, WEB). We ask that you forgive her and cleanse her from all unrighteousness (1 John 1:9, WEB). We pray against any potential pregnancy that may result from this sin, knowing that you are a merciful God who forgives and heals. In Jesus' name, we pray. Amen."
However, we must also address the root of the issue. We encourage you to repent of this sin and turn away from it. God's plan for sexual intimacy is within the bounds of marriage between a man and a woman. We urge you to pursue purity and self-control, as God's Word teaches (1 Thessalonians 4:3-5, WEB).
Additionally, we want to ensure that you understand the importance of faith in Jesus Christ. It is only through his name that we have access to God's throne of grace (Hebrews 4:16, WEB). If you haven't already, we encourage you to put your faith in Jesus Christ for the salvation of your soul.
Lastly, we highly recommend seeking counsel from a local church or a trusted Christian mentor to help you navigate this situation and grow in your faith. We are here to support you in prayer and to help you walk in obedience to God's Word.
