Luke 16

v1-18: We are to notice the shrewd way the man made the most of the present opportunity to provide for his future needs rather than his dishonesty toward his master.  "The wisdom of worldly people in the concerns of this world is to be imitated by us in spiritual matters: they are motivated to make the most of every opportunity, to do first what is most necessary, to prepare for winter in summer and harvest, to grab hold of a good bargain when it is offered them, to trust the faithful and not the false. Oh that we were so wise in our spiritual lives!"

v19-31: Within the parable we have a warning about the torment of hell for those who will not accept the offers made of eternal life.  "As soon as the soul leaves the body, it goes immediately to either heaven or hell, to comfort or torment... In heaven, there is eternal comfort. On the other hand, hell will truly be hell to those who go there from the midst of enjoying all worldly delights and pleasures."

Luke 17

v1-10: Stumbling blocks will come to God's people.  Persecutors who "cause injury."  Deceivers who "corrupt Christ's truths and ordinances and so trouble the minds of the disciples." Professing Christians who "lead disgraceful lives and so weaken the hands and sadden the hearts of God's people."  Jesus pronounces a woe on those who harm His followers in this way.

v11-19: The blood of Christ is powerful to cleanse everyone and anyone with spiritual leprosy who cry out for mercy.  If we have received this cleansing, we "should make it known to others, so that they too may praise God and may be encouraged to trust in him."

v20-37: The kingdom of God is a spiritual kingdom.  It does not have "external show as other kingdoms have".  Christ says that when it comes we may not be aware of it, this is because rather than changing people's outward condition, it changes their hearts and lives. "We must not think that Christ’s church and cause are lost because they are not always equally visible and effective."
