Jesus instructs the disciples to avoid tempting people to sin, to lovingly confront sin, and also forgive when people sin against us. This causes astonishment by the disciples who ask for more faith. Jesus lets them know the issue is not needing great faith, but realizing they trust a great God. Then, lest they get self-righteous or proud of their deeds or faith, they should realize they are only doing their duty.
Jesus continues to challenge the Pharisees due to their love of money (16:14). Now he gives a parable challenging their assumptions about wealth and who is blessed by God. Through the story, Jesus calls us to live with open-eyed generosity to those in need around us. In this Jesus shows them that God’s Word is enough for us to live a life that honors Him.
