In this section of Luke's gospel, Luke begins a progressive teaching section that races toward what we commonly know as the 'sermon on the mount' (which happens on a plain in Luke's Gospel). Luke shows Jesus subverting many of the religious assumptions of his day through his ministry of healing (the leper and paralytic), eating (fellowship with "sinners"), and reworked spirituality (fasting and sabbath keeping).
One of Jesus' main actions in the gospels is the call to reexamine ourselves and our practices in light of God's work among us. As you have time, read through chapters 5 and 6 of Luke. As you pray today, use those moments in prayer to ask God to subvert your own assumptions of what it means to follow Jesus.
