We hear your frustration and the strain you are feeling in your home, and we want to bring this before the Lord together with you in Jesus' name. We understand that living with constant loud noise can be wearing, especially when you are trying to work and handle important responsibilities, and we also hear your concern for your mother as she ages while caring for your brother.
Yet we must lovingly rebuke the way this request is framed, because it does not align with how God calls us to view and love family. Your brother is not an inconvenience to be removed, he is a person made in the image of God, fearfully and wonderfully made as Psalm 139:14 reminds us. His autism and the vocalizations that come with it are not willful defiance to annoy you, but often a way he regulates and expresses himself without understanding the impact on others. To pray that he would just shut his mouth and to speak of him as weird and as someone to be put away out of annoyance reveals a heart that needs God's compassion and patience. We are called to bear with one another in love with all lowliness and humility, with patience as Eph 4:2 teaches, and to put on a heart of compassion, kindness, lowliness, humility, and perseverance as Col 3:12 says. Love is patient and is kind as 1 Cor 13:4 tells us, and it does not dishonor others.
We also need to address the way you speak about your brother and your mother. Let no corrupt speech proceed out of your mouth, but only what is good for building others up as Eph 4:29 says, and be quick to hear, slow to speak, and slow to anger as James 1:19 instructs. Your mother has faithfully borne a heavy burden of caregiving, and God commands us to honor your father and your mother as Ex 20:12 says, which includes honoring her sacrifice and approaching any conversation about her future and your brother's care with deep respect, gratitude, and love, not with contempt for the one she cares for. Bear one another's burdens, and so fulfill the law of Christ as Gal 6:2 teaches.
It is understandable to be concerned about what care will look like as your mother gets older, and seeking wisdom about long term care, respite, or supported living can be a loving and responsible thing to consider when done out of love for both your mother and your brother and for his wellbeing, not merely to remove an annoyance. If that is needed, it should be sought prayerfully, with your mother's input, with counsel from trusted believers, and with your brother's dignity kept central. We encourage you to talk gently with your mother about her needs and to explore help from family, church, and community resources rather than speaking of your brother as a problem to be disposed of.
We also noticed your request did not mention the name of Jesus Christ. We want to remind you that it is only by the name of Jesus that we have access to God, and there is no other name by which we can be saved. Jesus said I am the way, the truth, and the life. No one comes to the Father, except through me as John 14:6 says, and 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 as Acts 4:12 says. If you have not already, we urge you to put your trust in Jesus Christ, believing that He died for your sins and rose again, and confess Him as Lord as Rom 10:9 teaches, so your prayers are heard through Him.
We pray together for you now.
Father in heaven, we come before You in the name of Jesus Christ and ask for Your mercy and grace in this home. Lord, forgive us where we have harbored anger, impatience, and unloving thoughts toward those You have placed in our lives. Create in our brother who submitted this request a new heart of compassion and patience toward his older brother, help him to see his brother as You see him, precious and worthy of love and dignity. Give him self control over his speech and his anger, and help him to speak with kindness and respect. Lord, we lift up his older brother to You, You know his needs and his struggles, bring him peace, comfort, and calm, and help him to feel safe and loved in his home. Strengthen his mother, Lord, renew her strength as she ages, provide for her rest and support, and give her wisdom for the future. Grant this family wisdom as James 1:5 promises to those who ask, to know how best to care for one another, to manage daily challenges like noise and work calls with practical solutions, and to seek help that honors You. Help them to love one another deeply and to bear with one another in love, for Your glory. In Jesus' name we pray, amen.
We encourage you to ask God daily for patience, to seek practical ways to show love such as using headphones or adjusting your call schedule when possible, offering to give your mother a break, and spending time seeing your brother as a person to be loved rather than a noise to be silenced. As you grow in Christ, He will help you love with His love.
