We are truly saddened to hear about the situation your daughter is in and we will join you in praying for her. Firstly, we need to address that your daughter is in a relationship that is not aligned with biblical principles. The Bible is clear that we should not be unequally yoked with unbelievers (2 Corinthians 6:14), and if the man she is with has a history of cheating, he is not living in a way that honors God. It is good that she wants that in a marriage and we have the scriptures that support her desire.
We rebuke the spirit of fear and low self-worth that may be keeping her from leaving this relationship. God has not given us a spirit of fear, but of power, love, and self-control (2 Timothy 1:7). Your daughter is a child of God, and she is precious in His sight. It hurts us to think of a young lady not knowing her value in Jesus Christ.
Let us pray for her confidence and strength to leave this relationship and trust God for her future. There is no other name but the name of Jesus to pray to God. It is by the name of Jesus that we are saved. If she believes in Jesus Christ she has access to God the Father.
Dear Lord Jesus,
We lift up this precious daughter to You, asking that You would fill her with Your confidence and strength. Help her to see herself as You see her, and give her the courage to leave this relationship that is not honoring to You. Father, give her the confidence that You will bring a godly man into her life, a man who will love her as You do, who is pure and not been with another. A man that if he is married to her will love her as You love Your Church (Ephesians 5:25). Help her to trust in Your timing and Your ways, and to wait for the godly spouse that You have for her. In Jesus' name, we pray. Amen.
We encourage your daughter to spend time in God's Word, seeking His will for her life. She should surround herself with a community of believers who will support and encourage her and pray for her daily. Remind her that God loves her deeply and has a good plan for her life (Jeremiah 29:11). If she believes in Jesus Christ, she is a child of God. If she does not, help her to make that decision. May God give her the confidence and strength to leave this relationship and trust in Him and His promises.
In closing, we are reminded of the promise in Psalm 34:4-5: "I sought Yahweh, and he answered me, and delivered me from all my fears. They looked to him, and were radiant. Their faces shall never be covered with shame." May this be true for your daughter, as she seeks God and trusts in Him.
