Jesus told the parable of the Pharisee and the tax collector "to some who trusted in themselves that they were righteous, and treated others with contempt" (Luke 18:9). Luke gives us the target audience before the story even begins, and it is a uncomfortably accurate description of the religious pride that can infect any believer. The parable is a mirror held up to every heart that has ever compared itself favorably to someone else.
Two men went up to the temple to pray. The Pharisee stood by himself and prayed: "God, I thank you that I am not like other men — extortioners, unjust, adulterers, or even like this tax collector. I fast twice a week; I give tithes of all that I get" (Luke 18:11-12). Notice the direction of his prayer: it is entirely horizontal. He compares himself to other people, not to God. His standard is the sinners around him, not the holiness of the One he claims to address. And his résumé of righteousness — fasting, tithing — is presented as grounds for God's approval.
The tax collector, by contrast, "standing far off, would not even lift up his eyes to heaven, but beat his breast, saying, 'God, be merciful to me, a sinner!'" (Luke 18:13). His prayer is seven words in Greek. He does not list his accomplishments (he has none to list). He does not compare himself to anyone else. He does not make excuses. He simply throws himself on the mercy of God, acknowledging the truth about himself: he is a sinner, and he needs mercy.
Then comes the verdict that must have stunned Jesus' original audience: "I tell you, this man went down to his house justified, rather than the other" (Luke 18:14). The tax collector — the traitor who collaborated with Rome, the extortioner who grew rich on his neighbors' misery — went home right with God. The Pharisee — the Bible-believing, commandment-keeping, tithe-giving religious leader — did not. The difference was not in their sin (both were sinners) but in their posture. One came claiming righteousness; the other came begging for mercy.
Jesus concludes with the principle that undergirds the entire biblical teaching on pride: "For everyone who exalts himself will be humbled, but the one who humbles himself will be exalted" (Luke 18:14). This is not merely good advice; it is a law of the spiritual universe as fixed as gravity. The way up is down. The path to justification is not through self-justification but through honest confession. The tax collector's seven-word prayer — "God, be merciful to me, a sinner!" — is the only prayer that every human being can pray with complete sincerity, and it is the only prayer that guarantees a hearing in heaven.
