Luke 17:7

say unto him by and by--The "by and by" (or rather "directly") should be joined not to the saying but the going: "Go directly." The connection here is: "But when your faith has been so increased as both to avoid and forgive offenses, and do things impossible to all but faith, be not puffed up as though you had laid the Lord under any obligations to you."

In this chapter we have, I. Some particular discourses which Christ had with his disciples, in which he teaches them to take heed of giving offence, and to forgive the injuries done them (Luk 17:1-4), encourages them to pray for the increase of their faith (Luk 17:5, Luk 17:6), and then teaches them humility, whatever service they had done for God (Luk 17:7-10). II. His cleansing ten lepers, and the thanks he had from one of them only, and he a Samaritan (Luk 17:11-19). III. His discourse with his disciples, upon occasion of an enquiry of the Pharisees, when the kingdom of God should appear (v. 20-37).

17:7-10 In Greco-Roman culture, servants existed to serve their masters faithfully. Faith (17:5-6) entails obedient submission to Christ and his commands.
