We understand your concern for your former fiancée and we will join you in prayer, seeking God's intervention in her life. However, we must address this situation with biblical principles in mind.
Firstly, we should pray for her healing and deliverance. In Mark 16:17, Jesus said, "These signs will accompany those who believe: in my name they will cast out demons; they will speak with new languages." We have authority in Jesus' name to pray against any demonic influence. Let's pray:
"Dear Heavenly Father, we come before you in the name of Jesus Christ. We plead for Naelael's former fiancée, that you would heal her mind and deliver her from any form of demonic oppression. We command any evil spirit to leave her in Jesus' name. Restore her mind and help her to return to the person she once was. In Jesus' name, we pray. Amen."
However, we must also remember that the Bible advises us not to be unequally yoked with unbelievers (2 Corinthians 6:14). If your former fiancée is not a believer in Christ, or if she has turned away from her faith, it is important for you to seek God's will in your relationship with her. It is crucial that you both share a strong faith in Jesus Christ as the foundation of any future relationship.
Moreover, it is only through Jesus Christ that we have access to God (John 14:6). If your former fiancée is not committed to Christ, we encourage you to pray for her salvation above all else.
Lastly, we should also pray for your healing and peace. Breakups can be difficult, and it's important to seek God's comfort and guidance during this time. Psalm 147:3 tells us that God "heals the broken in heart, and binds up their wounds." Let's pray for your healing as well.
"Lord, we also pray for Naelael. Comfort their heart and help them to trust in your plan for their life. Give them peace and guide their steps in the days ahead. In Jesus' name, we pray. Amen."
Continue to trust in God, Naelael. He has a good and perfect plan for your life (Jeremiah 29:11).
