After addressing the obligations Jesus’ disciples have to others, He talks briefly about the obligations they have toward God. This conversation begins with the disciples saying, “Increase our faith” (17:5). The disciples’ words here may have been a reaction to Jesus’ last statements about the high standards He had given them regarding their relationships with others. They knew that they needed Jesus to give them more faith if they were going to be able to achieve these standards. Jesus responds to their request for more faith by saying, “If you have faith as a mustard seed, you can say to this mulberry tree, ‘Be pulled up by the roots and be planted in the sea,’ and it would obey you” (17:6). Jesus was revealing that the amount of a person’s faith is not what is most important, but rather the object of that faith. God alone must be the source of a person’s faith and the disciples had to realize that they could never maintain right relationships with God or others without exclusive faith in Him. In case the disciples felt as if obeying Jesus’ commands through faith in God made them special, Jesus reminded them that these obligations were expected duties (17:7-10).
It is apparent that some time lapsed between Luke 17:10 and Luke 17:11, so we find Jesus stopping somewhere near Samaria and Galilee while on His way to Jerusalem (17:11). When He arrived in this village, ten men with leprosy shouted from a distance, “Jesus, Master, have mercy on us!” (17:12-13). Jesus immediately cleansed all ten lepers of this horrible disease, but only one of them, who was a Samaritan, returned to thank Jesus for His miraculous work (17:14-16). When Jesus saw that only one of them returned to give thanks He said, “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?” (17:17-18). The fact that the only leper who returned to give thanks was a Samaritan, shows that Jesus is teaching about the acceptance of Him by the Gentiles while the Jews continued rejecting Him. Salvation from the penalty of sin has been offered to all people (Jews and Gentiles), but only applicable to those who receive it by faith in Jesus Christ.
Dear God, with Your help, I desire to do Your will.
