Now that is so important, because if my righteousness depends on my doing anything, it becomes my own righteousness. It is no longer an alien righteousness, and it is not the righteousness of God. Faith is then made into a work, and then grace is no longer grace. If any part of justification is our doing—if we contribute to the basis of our righteousness in any way—then there is no Gospel, and we are all damned in our sins. God’s holiness is so magnificently perfect, His standard is so high, and our depravity is so pervasive, that all of our righteousness must be a free gift of His sovereign grace, because we could never earn it.
498 years ago, on October 31, 1517, Martin Luther famously nailed his 95 Theses to the Castle Church door in Wittenberg, Germany, kick-starting the Protestant Reformation. Nearly 500 years later, God’s people reserve this day to celebrate the rescue of His Word from the shackles of Roman Catholic tyranny, corruption, and heresy. The glorious Gospel of Jesus Christ as revealed in the sufficient Scriptures had been recovered, and it’s been doing its saving work ever since.
Romans 1:16–17 stands at the heart of the Reformation, especially because of how central it was in Luther’s conversion. Luther speaks of how he had hated the phrase, “the righteousness of God,” because he understood it to be speaking only of God’s standard of righteousness by which He would judge unrighteous sinners. But eventually, he says, “I began to understand that the righteousness of God is that through which the righteous live by a gift of God, namely by faith. Here I felt as if I were entirely born again and had entered paradise itself through the gates that had been flung open.”
Today, as we reflect upon and remember the grace of God that fell upon the world in the Protestant Reformation, I want to reflect upon the Gospel that made it happen—and particularly the concept of righteousness which was so central to the regeneration of the great reformer. And to do that I want to focus on another text that Paul penned, which gives us wonderful insight into the saving righteousness of God. In Philippians 3:9, Paul explains what it means to be found in Christ—namely, “not having my own righteousness, which is from the law, but that which is through faith in Christ, the righteousness which is from God by faith” (NKJV).
In this verse, Paul contrasts two different kinds of righteousness. And really he is contrasting two systems of salvation, because the only way one can be saved is to be found righteous before God. And though Paul is contrasting Christianity with Judaism in particular, what he says about Judaism can be applied to every other religious system in the world. As John MacArthur has often said, there are only two categories of religion in the world: (a) the religion of human achievement, where man works to achieve his own righteousness; and (b) the religion of divine accomplishment, where God accomplishes righteousness on man’s behalf and then freely gives that righteousness as a gift. The religion of divine accomplishment is Christianity. The religion of human achievement is every other religious system in the history of mankind. These two religions are delineated very carefully in Philippians 3:9.
The Source of Righteousness
Note first the source of saving righteousness. Paul says, “…not having my own righteousness,which is from the law, but that which is through faith in Christ, the righteousness which is from God by faith.”
In the religion of human achievement, the source of righteousness is law-keeping. There is some moral and/or ritualistic standard by which man is to order his life, and if he does that successfully, he may achieve a righteousness that is acceptable to his god. He earns his righteousness by keeping a law—by doing good works—whether that’s the Law of Moses or Roman sacramental system, his hope is that obedience to that standard is able to provide righteousness.
But in the religion of divine accomplishment, the source of righteousness is God Himself. InGalatians 3:21, Paul says that no law has been given which is able to impart life. Because of humanity’s total depravity—because the depth of our sinfulness runs to the very core of our being—the only thing that law could do was to arouse our sinful passions and demonstrate our inability to obey as we ought. That’s why Paul says in Romans 3:20: “…by the works of the Law no flesh will be justified in [God’s] sight; for through the Law comes the knowledge of sin.” Because we are sinful to the core, the standards of God’s righteousness can never free us from sin; they can only point out where we have continued to fall short of God’s standard.
And so Paul doesn’t want a righteousness that is sourced in the law; no such thing could exist!
