He needs prayer for his anger when he gets mad he wants to kill people so pray that stop and he let God put all his love in him.
Dear Lord Jesus,
You said where 2 or 3 are gathered, you are also there. Please lift up this dad's spirit and let him feel your loving presence in his life. Please settle your spirit into his bones, bringing him peace and calmness, and bless him with the knowledge to seek help in anger management. In your precious name, Jesus Christ, we pray. Amen.
