The story of Zacchaeus’ encounter with Jesus is exclusive to the Gospel of Luke and is the last encounter of Jesus with outcasts before he enters
The desire of Zacchaeus to see Jesus is a genuine one. He shows it is genuine by his willingness to overcome any obstacles that come in the way of his seeing. He is willing to persevere and do all that is required of him. His perseverance is rewarded by his meeting Jesus and being transformed by him.
