In context, here is the paragraph the phrase is in:
Rather, James describes faith that is lived out—demonstrated by actions. Without the actions that show the faith, it’s as useless as if you tell a hungry homeless person to be warmed and fed without giving them a thing to eat or anything to keep them warm. Words alone are as empty as the body without the spirit.
Out of context, here is what came to mind when I saw the phrase:
I had been racking my brain, stressing about where to go next with one of my stories. So, I started writing. Aimlessly. Without purpose.
At the time, and even after I read my words, I didn't realize that I was writing words alone.
So when I saw this phrase, it jumped out at me. It was like being struck in the face with a camera. (I had no idea it was coming; I turned a corner, and *smack!*)
Words alone are as empty as the body without the spirit, and just as repulsive, too.
