Update on my Grandpa

Hey Everyone,
I haven't updated on my grandpa for awhile, so I figured I should get you all up to speed. He has cancer. There are two tumors on his spine and one is his brain. They have done some radiation treatments and now they have to wait for a bit to see if it helped. My grandpa is still in the hospital because he isn't strong enough to leave. He has alot of weight since he has been in the hospital. They also said that he has to get stronger so that they can give him chemotherapy which I think they want to do but can't.
I'm really worried about him. Me and my family have been getting updates on him from his wife as we have all had colds for the past week or two and we can't visit him when we are sick. We were told on saturday that he wasn't really eating and he was looking like he is giving up. Today, we were told that he isn't eating and has stopped talking to anyone. I think he has just given up because he hasn't been given a prognosis yet because they need to see if the radiation helped or not and they can't tell right away. It seems like he thinks that there is no hope. He doesn't believe that he will get better because he hasn't been told if he can get better.
Please pray for him. He doesn't know Jesus so pray that somehow through this he will come to know him. Pray for my family too, especially my mom, she is very upset and worried about him and it is stressing her out and affecting her the most which is understandable considering it is her father.
Thank-you guys so much,
