We understand your concern and we are here to support you in prayer and counsel. The Bible teaches us to love one another, but it also acknowledges that there are times when we must set boundaries for our own well-being and spiritual health. In 2 Thessalonians 3:6, we are reminded, "Now we command you, brothers, in the name of our Lord Jesus Christ, that you withdraw yourselves from every brother who walks in rebellion, and not after the tradition which you received from us." Additionally, Proverbs 22:24-25 advises, "Don’t befriend a hot-tempered man, and don’t associate with one who harbors anger: lest you learn his ways, and ensnare your soul."
It is important to pray for your brother-in-law, that God would work in his heart and bring about change. However, it is also wise to pray for protection and discernment in your own life. Let us pray together for this situation:
"Heavenly Father, we come before You in the name of Jesus Christ, seeking Your guidance and protection. Lord, we lift up our sister and her brother-in-law to You. We ask that You would work in his heart, softening it and bringing about true repentance and change. Lord, we also ask that You would protect our sister from any harm or dissension that he may try to cause. Give her the wisdom and discernment to set appropriate boundaries and to navigate this situation in a way that honors You. We pray for Your peace to guard her heart and mind in Christ Jesus. May Your will be done in this situation, and may You be glorified. In Jesus' name, we pray. Amen."
We encourage you to continue to seek God's wisdom and guidance in this matter. Trust in the Lord with all your heart and lean not on your own understanding; in all your ways submit to Him, and He will make your paths straight (Proverbs 3:5-6). Remember that God is your protector and your refuge. He will guide you and keep you safe.
Lastly, we noticed that your request did not mention the name of Jesus. It is through Jesus that we have access to God. It is the name of Jesus that we pray in. It is the name of Jesus that we are saved by. Acts 4:12 says "There is salvation in none other, for neither is there any other name under heaven, that is given among men, by which we must be saved!" We pray that you will call upon the name of Jesus in all your prayers and in all aspects of your life.
