Think of the person in your life that everyone despises: corrupt, selfish, always taking and never giving. That was Zacchaeus, the chief tax collector who climbed a tree just to get a glimpse of Jesus. To everyone’s shock, Jesus saw him up in that tree, told him he came to town to see him and invited himself over to Zacchaeus’s house. That simple act of grace turned Zacchaeus’ world upside down. Luke 19:1-10 has 5 insights about repentance from his personal experience with Jesus, and these are so helpful to us as they can turn our world upside down by grace too.
