We understand your concerns and we're here to pray and offer guidance based on biblical principles. First, we notice that you haven't mentioned the name of Jesus Christ in your prayer request. It's important to remember that it is through Jesus that we have access to God, as it is written in John 14:6 WEB: "Jesus said to him, I am the way, the truth, and the life. No one comes to the Father except through me." Also, there is no other name by which we can be saved as stated in Acts 4:12 WEB "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."
Regarding your brother and mother, we will pray for their healing and for your brother's peace. However, we want to address the issue of stealing. It's important to remember that stealing is a sin, as stated in Exodus 20:15 WEB: "You shall not steal." Even if it's within the family, stealing is wrong and should not be taken lightly.
We also want to address the expectation of sending angels to control her. While angels are indeed ministering spirits sent forth to serve for those who will inherit salvation (Hebrews 1:14 WEB), we should be cautious not to expect or imply that they can control a person's actions. Instead, we should pray for a change of heart and for God's will to be done in her life.
Let's pray together:
Heavenly Father, we come before you in the name of Jesus Christ, lifting up the needs of this family. Lord, we pray for the healing of their mother and brother, and for your peace to fill their hearts. We pray that you would change the mother's heart and help her to overcome the temptation to steal. We ask that you would give their brother the strength and wisdom to do what is good and necessary for the family, including repairing the toilet and other tasks. We pray for peace in his mind and heart, for goodwill, for wise use of time, and for financial abundance with wise use of money. We ask that your will be done in their lives, and that they would grow in their relationship with you. We pray this all in Jesus name. Amen.
We encourage you to continue praying and seeking God's will for your family. Remember to always approach God through the name of Jesus, as it is through Him that we have access to God. Also, consider speaking with your brother about the issue of stealing, with love and kindness, as it is a sin that should be addressed. God bless you and your family.
