We are deeply grieved to hear of your sister’s situation, and our hearts ache with yours as you witness this painful separation. The enemy seeks to steal, kill, and destroy (John 10:10), and it is clear he is at work here, attempting to sever the bonds of family and replace them with ungodly influences. The control you describe—physical, mental, and spiritual—is not of God, for "where the Spirit of the Lord is, there is liberty" (2 Corinthians 3:17). This is oppression, and we must stand against it in the authority of Jesus Christ.
First, we must address the spiritual warfare at play. The servants you mention are not acting in alignment with God’s will, and their influence over your sister is a snare. The Bible warns, "Do not be deceived: ‘Bad company corrupts good morals’" (1 Corinthians 15:33). It is not loving to ignore this; we must rebuke the enemy’s work and pray for your sister’s deliverance. The spirit of control and deception must be broken in Jesus’ name. We declare that she will remember her family, her true identity in Christ, and the love that surrounds her.
We also lift up your sister’s husband, for Scripture commands, "Husbands, love your wives, just as Christ also loved the church and gave himself up for her" (Ephesians 5:25). If he is complicit in this separation, he is failing in his God-given role to protect and nurture his family. We pray for conviction and repentance in his heart, that he would lead his household in a way that honors God and preserves the unity of family.
For your sister, we pray for clarity and restoration. The Word says, "The Lord is near to the brokenhearted and saves those who are crushed in spirit" (Psalm 34:18). She is not lost to you forever; God is able to break every chain and restore what the enemy has stolen. We plead the blood of Jesus over her mind, that she would be freed from deception and remember the truth. We also pray for her children, that they would be shielded from this ungodly influence and that their hearts would remain tender toward their true family.
Let us pray together now:
Heavenly Father, we come before You with heavy hearts, lifting up our sister and her family. Lord, we ask that You would break every chain of control, deception, and spiritual oppression over her life. In the name of Jesus, we rebuke the enemy’s work and declare that she is not forgotten by You or by her family. Father, we pray for her mind to be renewed by Your Word, that she would remember the love and truth that surrounds her. We ask for conviction and repentance in the hearts of those who are leading her astray, that they would turn from their ways and seek Your face.
Lord, we also pray for her husband, that You would soften his heart and help him to fulfill his role as a godly leader in his home. Protect their children, Father, and keep their hearts pure and open to Your truth. We ask that You would restore this family, reunite them in love, and heal every wound caused by this separation. May Your light shine into this darkness, and may Your name be glorified in their lives.
We trust in Your power to save, deliver, and restore. We ask all these things in the mighty name of Jesus Christ, the only name by which we are saved and through whom we have access to You. Amen.
Do not lose heart, dear ones. The battle is the Lord’s, and He is faithful. Continue to pray without ceasing (1 Thessalonians 5:17), and trust that God hears your cries. Stand firm in your faith, and do not grow weary in doing good (Galatians 6:9). Your sister is not beyond God’s reach, and neither are those who seek to harm her. Keep your hearts fixed on Him, and He will direct your steps.
Prayer Focus: God, Thank You for loving me. God, I ask You in Jesus’ name please bless me with everything that I stand in need of and everything You want me to have.
