In Luke 17, on his way to Jerusalem, Jesus passed through Samaria and Galilee. In one village ten lepers called out to Him, “Lord Jesus, have mercy on us!” (Lk. 17:13). He told them to the go show themselves to priests, and as they went they were cured of their leprosy (v14).
We note that in this instance Jesus didn’t heal them immediately. He didn’t reach out and touch them, but in the process of doing what He said to do, they were made whole. George MacDonald said “Obedience is the opener of eyes.” For these ten, obedience was also restored worship. Jesus sent them to the priests because then they would be ritually cleansed and able to worship God with His people.
But only one of those lepers, when he saw that he was healed, came back to Jesus, glorified God, fell down at His feet, and thanked Him. Jesus commented on this to the disciples: “Were there not ten cleansed? But where are the nine? Were there not any found who returned to give glory to God except this foreigner?” (v18). He was a Samaritan, not someone expected to seek the Lord.
Ten lepers sought Jesus, ten obeyed Him, and ten were healed as they went. But only one came back, glorified God, and thanked Him.
