Please know that I will be praying for your Dad, as well as for you & your sister. I will pass his situation along to my Church, too. I don't know if you or he has a personal relationship with Jesus Christ,but know that the Lord is there even when times are the darkest, as I'm sure they must be for your Dad, right now. I feel very fortunate; my Daddy just turned 75, and other than badly arthritic knees, and heart surgery 5 years ago,he's doing pretty good. Your posting made me realize that I shouldn't take him for granted. Who knows what lies ahead. I wish I had more to offer, but all I can do is pray. And I will.
