A Very Difficult Post

I've tried several times to post, but couldn't.
My Dad Martin, had a severe heart attack on Tuesday that stopped his heart.
I got the call on Tuesday while at work. Dad was just sitting in a chair
talking and then just slumped. Colleen called 911 and the EMS found him
in cardiac arrest. They with the help of the Lord were able to revive him
and get his heart beating again. He was rushed to St. Agnus hospital in Baltimore.
There they found one of his main arteries blocked and put in a stent.
He's been in intensive care since. The doctors have said that his heart is beating well, but could not predict how long he went without oxygen to his brain, so the first 72 hours would be critical to see if there was any damage.
Dad opened his eyes a little yesterday when I leaned over him and told him that I loved him, but that's about it.
We are praying so hard. My Dad is 81 years old and just a couple of months ago walked 6 miles for a marathon to support the Seeing Eye Dogs. So this is such a shock and my heart is just so full of sorrow and pain.
We are looking to our Lord for peace and comfort, but hope for prayers for my Dad to "wake up" from his sleep.
So, please, please say a prayer for my Dad Martin that he will wake up and come back to us.
