Please pray for my grandpa's surgery tomorrow

Will you all please pray for my grandpa who is having surgery tomorrow? He fell about 3 weeks ago and broke 7 ribs. Fluid has been collecting in his chest and the tubes that they have in his side aren't working fast enough to clean it out. He is 80 something and just got over Lymphoma cancer through chemo. The hospital has him all doped up on different medications and different tubes and things sticking out of everywhere. Please pray for his healing and most importanly his salvation. He claims to not believe in God but I know there is a soft spot in his heart. Thank you all very much. Tweet
