We are deeply saddened to hear about the situation your daughter is in, and we stand with you in prayer, seeking God's intervention and deliverance for her.
Firstly, let us address the issue in the light of God's Word. The Bible teaches us that we should not be unequally yoked with unbelievers (2 Corinthians 6:14, WEB), and that we should flee from evil (1 Thessalonians 5:22, WEB). The relationship your daughter is in is not only ungodly but also abusive and harmful.
Let us pray together:
"Dear Heavenly Father, we come before you in the name of Jesus Christ, pleading for the safety and deliverance of our sister's daughter. Lord, you see the bondage she is in, the manipulation, control, and abuse she is suffering. We ask you, Father, to break the trauma bond that has formed. Open her eyes, Lord, to see the truth of her situation, and give her the strength and courage to leave this abusive relationship.
Lord Jesus, you came to set the captives free (Luke 4:18, WEB). We claim your promise for her life. Break every chain of emotional, mental, and financial abuse. Bring her into a place of safety and healing. Surround her with godly counselors and supportive friends who can help her through this difficult time.
Holy Spirit, convict her heart. Help her to see that this relationship is not of you, and that true love is patient, kind, and does not harm (1 Corinthians 13:4-7, WEB). Guide her steps and bring her back to a place of faith and trust in you.
In Jesus' powerful name, we pray. Amen."
We encourage you to remain steadfast in prayer and faith. Remember the promise in Matthew 18:19 (WEB), "Again, assuredly I tell you, that if two of you will agree on earth concerning anything that they will ask, it will be done for them by my Father who is in heaven."
Also, do not be afraid to reach out to local authorities and domestic violence support services. They are equipped to handle such situations and can provide practical help and guidance.
Lastly, ensure that you and your daughter are both anchored in a personal relationship with Jesus Christ. It is only through Him that we have access to God's power and promises (John 14:6, WEB). If you have not yet accepted Jesus as your Lord and Savior, we encourage you to do so today.
