How does God's grace work in the story of Zacchaeus?

In the account of Zacchaeus, we see God's distinguishing grace at work. Despite Zacchaeus's reputation as a chief publican and a wealthy sinner, Jesus actively sought him out, demonstrating that His grace is not limited by human standards of worthiness. Zacchaeus's willingness to climb a tree to see Jesus shows both his desire and God's elective grace, with Christ calling him by name, revealing personal knowledge of him that brings immediate transformation. This transformation is evidenced by Zacchaeus's repentance and subsequent actions of restitution, which are not conditions for his salvation but rather fruits of God's grace in his heart. This illustrates the Reformed understanding that true salvation will manifest genuine change in behavior.
