May Tim glory in His Redeemer.
My dad died from pancreatic cancer. It wasn't discovered until later in the process (pancreatic cancer mimics other lesser problems). My dad died less than 2 months after diagnosis.
If God desires to heal, then Tim Keller will remain on earth a bit longer. Otherwise our enemy, death, will be victorious over the body, but not touch the soul and spirit. May Tom Keller be at peace with his Sovereign King.
I’ve heard the pancreas doesn’t have nerve endings and that’s why it’s usually too late when diagnosed. I said usually, as a Sister I used to attend church with a few years ago had stage two pancreatic cancer. She had part of hers removed and chemo and she seems to be fine, AFAIK.
