This particular verse of scripture describes how Jesus healed all ten lepers but only one came back to thank him.
The moral of the story is simple...
Many times God blesses us, heals us, restores us and gives us many wonderful things, however some of us never stop to really thank God for what he's done.
The story is a reminder of how we should stop and take time to show God our appreciation for the things that he's done in our lives..
Give thanks to the LORD, for he is good; his love endures forever
Psalms 118:1
