Know that your son, his loved ones & those who are treating him & taking care of him... are all in our prayers.... Years ago, our youngest daughter was in a terrible car wreck, suffered a brain injury and spent 3 weeks in a coma.. and then spent weeks & months in rehab at Children's Mercy Hospital in KC, Mo., so my wife & I understand your fears........ Know that the strength & love you need are found in the Love of our Lord..
