The story of Zacchaeus in Luke 19 teaches us about the importance of seeing others, the value of friendship, and the power of salvation. Zacchaeus, a despised tax collector, climbed a tree to see Jesus. Jesus saw him, called him by name, and invited Himself to Zacchaeus' house. This encounter led to Zacchaeus' repentance and transformation. The story reminds us to see those who feel invisible, extend friendship to the marginalized, and embrace the message of salvation.
