God is boundless and each man seeks him in his own way. Finding Him is the issue, not how or where I would think.
Hypocritical to ask for blessings on an injured son? I think not.
May God watch over your son and provide his medical team the skill to bring him through. May God's will, always perfect, be sought and achieved, but we pray that His Will is for your son to be returned to health and full function.
Prayers too for peace for you and those who love your son. May God speak to you wherever you are that you have communion with Him that provides the Peace that passes all understanding.
Keep the Son in your eyes!
