Can A Zebra Change

A beautiful, impactful, yet easy to perform, Gospel presentation with a standard utility prop. A blue striped silk is pulled from a tube with a blue striped interior. The scripture is shared that a "Leopard cannot change his spots" (or in this case, a Zebra, his stripes!)
When the silk is placed back in the tube it suddenly changes to a red striped silk! As a matter of fact the interior of the tube has also changed with it!
While a leopard may not be able to change his spots, God can change our sinful heart!
