Sarcasm...

I was once told that being sarcastic isn't very Christian and by the same person I was told that sarcasm isn't found anywhere in the Bible. I struggled with that often over the past few years after searching for the word “sarcasm” in the Bible and not finding it. However, just yesterday, a sermon was preached that described James 2:19 “You believe that there is one God. Good! Even the demons believe that--and shudder.” Sarcasm used by God...What do you think?
