Pray for movement to improve in his right side. He will not be able to walk on his own until his right legs movement improvents.
Pray for his vocal cords to strengthen so he can further communicate. He can say a few simple words and sounds right now, but his throat muscles were damaged and have to regain strength.
Pray for him emotionally. I know that it has to be tough to be completely mentally there, but to not be able to do things you once did. I know it gets frustrating for him, and that breaks my heart.
Pray for his mom, dad, and brothers. His mommy has not left his side for one day since the accident, and her entire world is taking care of Matt right now. Pray for them all in this valley of life.
