Hello Emily, am assuming you're a Christian. The bible says, once we asked Jesus for anything to just believe that He will do what needs to be done. So, we as Christians believe in faith that your granddaddy will get better. I pray Father in Jesus name that you be with Emily and her family at this time, give them your wonderful peace. I don't know if it's her mum or dad's daddy, but Father strengthen her parents as it seems like the granddaddy will be quite young. Keep them safe Father in Jesus name...work wonders/ miracles in their lives Lord. It's written where two or three agree upon anything it will be done, in Jesus name. Amen. Try not to worry Emily, your granddaddy is in God's hands and in our prayers.
