Parable on persistence Luke 11:5-8
Everyday Parables

 Everyday Parable Carol Moore member of RHUC

I'm starting to think about the toothpaste tube and how some people just squeeze while it's easy to get the paste out and then discard it, while people like me squeeze every last bit out of the tube and then rub it with a toothbrush to make sure nothing is lost.  Might be a parable in that.
