Luke 17:11-17 teaches us about 10 lepers who asked Jesus to cleanss them, and they were told to go to the priest for examination, but one of them seeing that he was cleansed returned to thank God. The man that gave thanks got more than healing, he got wholeness. Ingratitude stops man from receiving more either from God or man... No one wants to give to an ungrateful person.. Some doors are closed in peoples lives simply because they failed to return and say thank you.
