The one leper who returned loudly gave God the glory for his healing. He thereby acknowledged that Jesus was God"s agent. His prostrate posture and his thanksgiving expressed his great gratitude to Jesus (cf. Luke 5:12; Luke 8:41; Luke 18:11; Luke 22:17; Luke 22:19; Acts 5:10; Acts 28:15). The fact that he was a Samaritan rather than a Jew is the key point in the incident. Luke"s mention of this fact set the stage for Jesus" teaching that followed. [source][source][source]
