He also told this parable to some who trusted in themselves that they were righteous, and treated others with contempt: “Two men went up into the temple to pray, one a Pharisee and the other a tax collector. The Pharisee, standing by himself, prayed thus: ‘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.’ But the tax collector, standing far off, would not even lift up his eyes to heaven, but beat his breast, saying, ‘God, be merciful to me, a sinner!’ I tell you, this man went down to his house justified, rather than the other. For everyone who exalts himself will be humbled, but the one who humbles himself will be exalted.” (Luke 18:9–14, ESV)
From this passage, which man trusted God for his salvation? Which one saw God at work in his life? Most of the time the answer that is given is the second man because he cried out for God’s mercy while the Pharisee boasted of his own works. But look at the Pharisee’s prayer, “God, I thank you…” He indeed saw that it was God who had made him unlike other man. It was because of God’s good gifts that he was able to do the things that he did. However, he was trusting in what has become known as infused righteousness or an internal righteousness.
This Pharisee trusted in his own works, though given to him by God, for his salvation. As Calvin puts it in his commentary on this passage, “Hence we infer that men are not truly and properly humbled, though they are convinced that they can do nothing, unless they likewise distrust the merits of works, and learn to place their salvation in the undeserved goodness of God, so as to rest upon it all their confidence.” The fault of this man was not distrusting God for his salvation, but rather looking for God to create an internal righteousness that was sufficient to save him.
The tax collector however, does not trust in anything within himself. Rather, he acknowledges his sin and cries for God to be merciful to him. He does not point to any works of righteousness, God wrought or not. He know that he has no hope of salvation from God’s judgment within himself. Again, in theological terms, it could be said that he trusts in imputed righteousness. That is a righteousness which comes to us from outside ourselves that is not ours, but is counted (imputed) as ours by God. This righteousness is Christ’s that is imputed to us through his life, death, and resurrection. Not only were our sins imputed to him, but his righteousness to us.
This should give us hope when we sin, knowing that as God’s redeemed our standing before God is not based on an internal, God-given righteousness, but on the unchanging and always perfect righteousness of Christ. Also, it means that we can never “live the Gospel” or “be the Gospel.” To do so would be to say that the good news is what God has done in us, rather than what God has done in Christ. Instead of pointing people to an external righteousness in Christ, we would instead point people to our changed lives (see Objective Faith in a Subjective World).
