Oh dear, this poor guy, and poor you, stuck feeling so helpless. You're a bit short on information and I understand that's because probably you're just so tensed up and in a bit of a tailspin that it's hard to sit down and type out detailed descriptions and background. That's perfectly OK, let's just pray anyway.
================================
Dear Lord God, firstly I really want to thank you for our family. For Brooklyn I really want to thank you for all the sweet, fond and happy memories he/she has of his/her brother. Memories of daft, funny things that make Brooklyn smile, proud recollections of achievements, interactions with parents, other family members and shared friends. Lord God, in all these lovely times you were there as a strong invisible force looking after and nurturing them.
Recently though something happened that resulted in this tragic turn of events. Dear Lord God, I ask that you will exert your will in the lives of Brooklyn and his/her brother. Please God give Brooklyn real wisdom over emotion to see through these events and see the unfolding of your will. We would love to see a wonderful miracle defying the odds. I really hope that that's your will and if it is I plead and beg that you bring it about without any delay, and even better God, bring glory and honour to your name, that means so much to us.
Whatever the outcome, make Brooklyn a guide and a tower of strength leading his/her family through this crisis to the other side, wherever that may be. It's so good to know that you are in total and ultimate control of events, there's nothing random that's beyond you, and also that you love us with a dearest, kindest and most wonderful love that's so immense we could not begin to fathom it.
Lord God, glorify your name, and at the same time love and protect Brooklyn and his/her precious family and friends.
Amen
