Please pray for my grandpa

Hey guys

Right now, I am going through a rough time. I hope you guys read this post before this coming Sunday on the 6th. My grandpa has decided that this Sunday will be his last day on Earth. He's not a christian. I am trying my best to bring in someone to talk to him, but my family will most likely be against it. I will try, but it's really hard for me right now. It looks like my dad is really stressed out right now because of this. I don't want to anger him or my family. It will be awkward. I am really scared of what will happen. Please pray for my grandpa and my strength. Thank you
