We understand that you're seeking prayer and support for a legal situation and protection from a difficult family member. Firstly, we commend you for acknowledging the power of Jesus' name in your request, as it is only by His name that we can approach God the Father and be saved. Let's turn to God's word and pray together for this situation.
Let us remind ourselves that God is our defender and refuge. As it is written in Psalm 91:14-15 (WEB), "Because he has set his love on me, therefore I will deliver him. I will set him on high, because he has known my name. He will call on me, and I will answer him. I will be with him in trouble. I will deliver him, and honor him."
Regarding the legal issue, we should pray for God's will to be done and for justice to prevail. Let's also pray for wisdom for all parties involved, as Proverbs 2:6 (WEB) says, "For Yahweh gives wisdom. Out of his mouth comes knowledge and understanding."
Concerning the conflict with your father-in-law, Jesus Christ calls us to love our enemies and pray for those who persecute us, as written in Matthew 5:44 (WEB). This does not mean we should not seek protection from harm, but we should also pray for his heart to be softened and for reconciliation, if possible.
Let us pray together:
Dear Heavenly Father,
We come before You today in the name of Jesus Christ, seeking Your intervention in this legal matter. We pray for justice and mercy, and for Your will to be done in this case. Guide the authorities and all parties involved, granting them wisdom and discernment.
We also ask for Your protection from any harm or retaliation from this man's father-in-law. Keep him safe from harm, and if it is Your will, soften his father-in-law's heart and open a path for reconciliation. Help Christ to love and forgive, just as You have forgiven us.
Help Christ to trust in You completely and believe in Your power, and in the power of Jesus' Name.
We pray in the name of Jesus Christ, Amen.
