The Unmatched Superiority of Faith In Christ
Big Idea: The Way of Faith is Way Better than Any Other Way!
Paul wants every person to understand that God’s way of justifying people—by grace—absolutely excludes any possibility that we may take credit for our salvation. But another possible identification of this person is more specific: the Jew. Paul used this same language of “boasting” or “bragging” about Jews in 2:17, so he may be reminding Jews that they can no longer brag about their superiority to Gentiles. God justifies both Jew and Gentile on the same basis (see vv. 29–30).
His primary concern continues to be to show that Jews need the gospel, for by demonstrating this, he will have shown that all people need it.
Verse 28 is a famous statement of the doctrine of justification by faith, and, under the influence of Luther, many of us almost automatically add an “alone” after faith. The word is not, of course, found in the verse. But it legitimately brings out the sense of what Paul is saying (long before Luther, the Roman Catholic theologian Aquinas had also added it). For in denying that even the best human works can justify us (e.g., Jewish obedience to God’s holy law), Paul is, in effect, denying that anything a human being does will ever justify one before God.
Paul affirms the valid demand that God makes of people in the law, and that demand cannot simply be swept under the carpet. But one of the things Christ does is to fulfill the law on our behalf. We who are in Christ are therefore accounted as having fulfilled the law and been set free from its penalties for disobedience. It is, paradoxically, this very freedom from the law’s condemnation that puts us into a relationship in which true obedience, motivated and directed by the Spirit, can come about.
