Without you , we are but dust

In church this morning we were sitting beside a little girl and her mother when the preacher began his sermon.

..."Dear Lord," the minister began,
with arms extended toward heaven and a rapturous look on his
upturned face. "Without you, we are but dust." He would have
continued but at that moment the little girl sitting next to me who
was listening leaned over to me and asked quite audibly in her

shrill little four year old girl voice, "Mr, what is butt dust?"
