Let's bring your concerns to the Lord in prayer, seeking His will and guidance in this difficult situation. We must remember that God calls us to honor our parents, including in-laws, and to live in peace with others as far as it depends on us.
First, let's acknowledge and remember that our battle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms. Therefore, let's take up the full armor of God and pray with that understanding.
Let us pray:
Dear Heavenly Father, we come before You in the name of Jesus Christ, seeking Your intervention and guidance in this situation. We pray for this mother-in-law, that You would soften her heart and change her behavior. We ask that You would help her to speak the truth and to live in peace with her family. We pray that You would help them to live in peace and harmony, and that You would give them the strength and wisdom to handle this difficult situation.
We pray for this person who has brought this request, asking for the strength to love and forgive their mother-in-law.
We also pray that You would convict her of any sin in her life and bring her to repentance. We ask that You would help her to see the error of her ways and to turn from her wickedness. We pray that she is speaking lies and attempting to deceive. We rebuke that spirit of dishonesty in the name of Jesus and pray for truth to reign.
We also pray for her elder son, that You would guide him and give him wisdom in this situation. We ask that You would help him to make the right decisions and to do what is best for his family.
We pray for the requestor and their spouse and ask for the strength and wisdom to handle this difficult situation. We ask that You would help them to set appropriate boundaries to protect themselves and their family. We ask for Your protection over their marriage and their family, and that You would help them to live in peace and harmony.
We pray that You would work all things together for good, and that You would use this situation to bring about Your purposes in their lives.
We ask all of this in the name of Jesus Christ, our Lord and Savior, who lived and died and rose again that we might have life and have it more abundantly. It is in His name that we pray, Amen.
We encourage you to continue to pray for your mother-in-law and to seek God's will in this situation. Remember that God calls us to love our enemies and to bless those who curse us. We should pray for those who mistreat us and seek to live in peace with them.
We also encourage you to seek godly counsel and wisdom from other believers and to set appropriate boundaries to protect yourself and your family. Remember that God is faithful, and He will not let you be tempted beyond what you can bear. He will also provide a way out so that you can endure it.

Finally, we leave you with these words from Romans 12:18: "If it is possible, as much as it is up to you, be at peace with all men."
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.
