15 Then one of them, when he saw that he was healed, turned back, praising God with a loud voice; 16 and he fell on his face at Jesus' feet, giving him thanks. Now he was a Samaritan. 17 Then said Jesus, "Were not ten cleansed? Where are the nine? 18 Was no one found to return and give praise to God except this foreigner?" 19 And he said to him, "Rise and go your way; your faith has made you well."
Matthew Henry's Commentary on Luke 17:15-19
Commentary on Luke 17:11-19
(Read Luke 17:11-19)
A sense of our spiritual leprosy should make us very humble whenever we draw near to Christ. It is enough to refer ourselves to the compassions of Christ, for they fail not. We may look for God to meet us with mercy, when we are found in the way of obedience. Only one of those who were healed returned to give thanks. It becomes us, like him, to be very humble in thanksgivings, as well as in prayers. Christ noticed the one who thus distinguished himself, he was a Samaritan. The others only got the outward cure, he alone got the spiritual blessing.
