At church this morning, the sermon was about how we can find comfort from Jesus, who wants to free us from fear, and how we should try to bring comfort to others.
As the pastor said, one way to comfort
others is to listen to them. Maybe it's a good idea to give advice or
words of comfort, but the problem there is that the person seeking to
comfort someone else may say the wrong thing. See here and here, or the Book of Job.
