The Ten Lepers
The story of the ten lepers being healed by Jesus makes the obvious point of the importance of gratitude. Jesus tells ten lepers to go and see the priests at the Temple in Jerusalem. They set off and on the way they are healed. Nine continue on their journey. One returns to thank Jesus. And he wasn't even a Jew. He was a Samaritan. His religion was a hybrid one - of no worth at all as far as the Jews were concerned.
