We are truly concerned for your daughter and the situation she is in. First, we want to remind you that God's word tells us to "be not unequally yoked together with unbelievers" WEB 2 Corinthians 6:14. This means that, as followers of Christ, we should seek to be in relationships with fellow believers who share our faith and values.
We notice that your request does not mention the name of Jesus Christ. It is only by His name that we have access to God. The Bible states, "in Christ Jesus you who were far off were made near in the blood of Christ. For he is our peace, who made both one, and broke down the middle wall of partition, having abolished in the flesh the hostility, the law of commandments contained in ordinances, that he might create in himself one new man of the two, making peace; and might reconcile them both in one body to God through the cross, having killed the hostility thereby. Having come, he preached good news of peace to you who were far off and peace to those who were near, for through him we both have our access in one Spirit to the Father." The Bible also says, "in whom we have boldness and access in confidence through our faith in him." WEB Ephesians 2:13-18; 3:12.
Furthermore, the Bible tells us, "Therefore a man will leave his father and his mother, and will join with his wife, and they will be one flesh." WEB Genesis 2:24. This is the biblical design for relationships, that a man and a woman come together in holy matrimony. We encourage you to discuss this with your daughter.
We will pray that God will intervene and guide your daughter's steps. We pray that He will give her wisdom and discernment, and that He will lead her to a godly spouse who will love and honor both her and the Lord. We pray that your daughter will seek God's will for her life and that she will trust in Him to guide her. We pray for your daughter that "she will delight herself in the Lord and that He will give her the desires of her heart." WEB Psalm 37:4.
Heavenly Father, we lift up this daughter to You, asking for Your intervention in her life and her relationships. Guide her steps, Lord, and lead her to a godly spouse who will love and honor both her and You. Give her wisdom and discernment, and help her to seek Your will for her life. We ask this in the precious name of Jesus Christ, Amen.
