In the figure of Zacchaeus in today's Gospel, we have a portrait of a lost soul. He is a tax collector, by profession a "sinner" excluded from Israel's religious life. Not only that, he is a "chief tax collector." Worse still, he is a rich man who has apparently gained his living by fraud.
But Zacchaeus' faith brings salvation to his house. He expresses his faith in his fervent desire to "see" Jesus, even humbling himself to climb a tree just to watch Him pass by. While those of loftier religious stature react to Jesus with grumbling, Zacchaeus receives Him with joy.
Zacchaeus is not like the other rich men Jesus meets or tells stories about (see Luke 12:16-21; 16:19-31; 18:18-25). He repents, vowing to pay restitution to those he has cheated and to give half of his money to the poor.
By his humility he is exalted, made worthy to welcome the Lord into his house. By his faith, he is justified, made a descendant of Abraham (see Romans 4:16-17).
As He did last week, Jesus is again using a tax collector to show us the faith and humility we need to obtain salvation.
We are also called to seek Jesus daily with repentant hearts. And we should make our own Paul's prayer in today's Epistle: that God might make us worthy of His calling, that by our lives we might give glory to the name of Jesus.
