Luke 17:11-19
This is the fourth of five miracles in Jesus' journey to Jerusalem (Luke 11:14; 13:10-13; 14:1-4; 18:35-43). While Jesus does a wonderful healing here, the emphasis is upon the reaction to it rather than the miracle itself. The emphasis is on proper thankfulness that is a "gift" too.
Jesus is moving east to west along the boundary between Samaria and Galilee. He comes in contact with some Samaritans - Gentiles, who were disliked by the Jews. Jesus also met some lepers (cf. Luke 5:12-16) - at least one being a Gentile (Luke 17:16).
Ten lepers stood before Jesus - at a distance "and called out in a loud voice, Jesus, Master, have pity on us!" (Luke 17:12-13). Jesus responded. He did not touch the ten, neither was there pronouncement, i.e "Be clean!" (cf. Luke 5:13). Jesus simply says, "Go, show yourselves to the priests" (Luke 17:14). This was a command of "faith." As Hughes says, "The command was to do what a cured leper would do, following the regulations stipulated in Leviticus 14, which required examination by a priest. If they were cured, they would joyfully undergo an eight-day ceremony and then be reunited with their families." Jesus spoke the Word - and thus these lepers were physically healed, but they could not see the effects of their healing but in time; they were healed "as they went" (Luke 17:14).
Only one leper returned to give thanks for the miracle that was done in his life. He was a Samaritan - a Gentile - to a Jew, a foreigner, pagan, or heathen (Luke 17:15-16). His day began before Jesus with a "loud" plea for mercy (Luke 17:13) and ended with "loud" praise to God (Luke 17:15). The Samaritan "came back, praising God in a loud voice" (Luke 17:15) and "threw himself at Jesus feet and thanked him" (Luke 17:16). Jesus is God (see below).
Jesus commented upon the other nine lepers that were healed (Luke 17:17-18). Apparently, God was not the center of their gratitude. Like the shrewd money-manager (Luke 16:1-13), their focus was earth-bound, but not upward; that is on their knees looking up to the Cross. Then he said to the leper that returned, "Rise and go; your faith has made you well" (Luke 17:19). God's common grace blesses and satisfies many, but his saving grace - given only to some for whom he died (see below) - ends in a relationship of thankfulness. Only one leper was given saving faith and turned to establish a relationship (now at his "feet" (Luke 17:16), where before he was at a "distance" (Luke 17:12)) indicating the presence of salvation (cf. Luke 7:50; 8:48; 18:42).
This account of a healed leper is similar to another healing recorded in 2 Kgs 5:1-15. In Jesus's day, it comes as a surprise that nine Jews were healed, but only the one Samaritan healed gives thanks. Many who should have received Jesus did not. Unexpectedly, many outsiders did trust him.
