Praying for Brad to have peace in his heart and that he asks God to come into his life. Praying for Him to help heal Brad's heart of the hate and anger towards his past. You can't go back and change it, you need to find peace with it and let it go. Pray for the courage to really look at himself and make the changes inside to get himself to a happier place. Ask for grace and strength as he deals with the withdrawl and what may be hard days in craving a drink or whatever evils he is giving up.
"Peace on earth to those with whom God is pleased..."
