We understand that you're seeking a miracle for your family and help for someone to self-regulate and calm down. We're here to pray and offer guidance according to God's word.
Firstly, we thank you for acknowledging Jesus. The Bible tells us "For there is one God, and one mediator between God and men, the man Christ Jesus" (1 Timothy 2:5 WEB). It is only through Jesus that we can approach God the Father, and it is in His name that we pray and receive salvation, peace, and miracles.
For the situation at hand, we encourage you to read and apply Proverbs 15:1 WEB, "A soft answer turns away wrath, but a harsh word stirs up anger." Also, consider Ephesians 4:31-32 WEB, "Let all bitterness, wrath, anger, outcry, and slander be put away from you, with all malice. And be kind to one another, tenderhearted, forgiving one another, just as God also in Christ forgave you."
Let us pray together:
"Father, in the name of Jesus, we come to You as a family seeking a miracle. We ask that You intervene in our situation and grant us the breakthrough we need. Help us to enjoy our time together as a family, filled with love, understanding, and peace.
Lord, we also lift up to You the member of our family who needs help with self-regulation and calming down. Please grant them the fruit of the Spirit, which is self-control (Galatians 5:22-23 WEB). Help them to put away all bitterness, wrath, anger, and malice, and to be kind, tenderhearted, and forgiving, just as You in Christ have forgiven us.
In Jesus' name, we pray and believe that we have received what we've asked according to Your will. Amen."
Remember, it's important to put away all forms of outbursts of anger, and to be kind and forgiving to each other. It is only by applying God's word that we can see true and lasting change. Trust in God, and He will make a way for your family.
