Are they just words?

I have a very deep emotional reaction to the 6 words below; they make me cry.

I don't know if my reaction to this is because of my longing to reach the place where I can really follow the words or if it is because of the circumstances when these words were last spoken to me. It was a very kind man, a Chaplin from the local fire department who was trying to help ease my soul when I was in turmoil.

John 14:1 " Let not your heart be troubled..."
