Bible Riddle

This is a pretty funny riddle after (or if) you figure out the answer and then think again about a particular part of the clue:

I have 13 arms, 10 legs, 2 head, and smell like burnt denim. What am I?

You can read through Romans 3:1-6 to find the word that answers this particular Bible riddle.

Good luck, but I think you can figure it out.
