 When you do want to comfort someone in grief, there are many good things that you can say. You can say, I'm sorry for your loss. You can say, it's okay to grieve. And for a Christian who dies especially, you can say, they will rise again. Or you can say, I'm so thankful that Jesus saved them. Or many times you don't really have to say much of anything at all, but you can sit in silence with someone, and that can be a comfort.
