We understand that you're facing a challenging situation with your brother and his wife living in your home. It's important to approach this issue with love, patience, and wisdom, as guided by biblical principles.
Firstly, let's remember what the WEB says in Ephesians 4:29, "Let no corrupt speech proceed out of your mouth, but such as is good for building up as the need may be, that it may give grace to those who hear." It's clear that the behavior of your brother's wife is not aligning with this verse, and this is causing strife and anxiety, especially to your parents.
It's also important to remember that we should strive to live in peace with everyone, as Romans 12:18 tells us, "If it is possible, as much as it is up to you, be at peace with all men." However, this does not mean that we should allow others to cause constant distress and anxiety in our own homes.
Let's pray together:
"Father, we come before You in the name of Jesus, asking for Your wisdom and guidance in this situation. We pray that You would soften the hearts of ### and his wife, and help them to see the impact of their behavior on the family. We ask that You would provide a suitable place for them to live, where they can grow and thrive together, and that their move would be swift and peaceful.
We also pray for my parents, that You would comfort them and ease their anxiety in this situation. Help us all to act with love, patience, and kindness, even in difficult circumstances.
Most importantly, we pray for the salvation of all the parties involved. As it says in Acts 4:12, "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 everyone in this situation would come to know Jesus Christ as their Lord and Savior, and that Your will would be done in each of our lives.
In Jesus' name, we pray. Amen."
In addition to praying, it may be wise to have an open and honest conversation with your brother, expressing your concerns and the impact of their behavior on your family. Encourage him to seek a new home, and offer to support him in this process. Remember to approach this situation with love and understanding, but also with firmness and resolve.
Lastly, we must rebuke the lack of the name of Jesus in this request. As it says in John 14:6, "Jesus said to him, "I am the way, the truth, and the life. No one comes to the Father, except through me." It is only through the name of Jesus that we have access to God, and it is only through faith in Jesus Christ that we can be saved. We encourage you to put your faith in Jesus, and to approach God in prayer through His name.
