The heart of the Protestant Reformation is that God declares you to be righteous by faith alone, in Christ alone. If you don’t believe this, then you do not have the true good news. This doctrine is often called “justification by faith.” It’s a churchy phrase that has lost some of its punch—many Christians know it’s “good,” but perhaps they can’t explain what it means. This article will show how the apostle Paul explains this vital truth in Romans 3:19-31. It’s a very big deal. Maybe the biggest deal ever.
The problem
We can trace the “Christian” family through three broad streams:
- Eastern Orthodoxy. This stream hails from the traditional Christian lands in modern-day Greece, Turkey, Syria, etc. It largely went its own way after the Western Roman Empire crumbled to bits. We won’t be discussing this tradition here.
- Roman Catholicism. This branch developed as a recognizable institution in the remnants of the western Roman Empire beginning from the late 6th century.
- Protestants. This is the variegated stream which broke away from the corruption of the Roman Catholic church beginning in the early 16th century, first in modern-day Germany, then in Switzerland, and beyond. If you’re a Christian in the West (that is, you’re not a convictional Roman Catholic and do not belong to a cult), then you’re in the “Protestant” stream—whether you know it or not.
Many churches celebrate “Reformation Sunday” on the Lord’s Day closest to 31 October to commemorate Martin Luther’s challenge to debate a series of theses about reforming the corrupt Roman Catholic church.
The Roman Catholic church believes good and true things about the trinity, about sin, about salvation, about Jesus, the virgin birth, our Savior’s life and death, his resurrection, his ascension, his return, and the new heavens and new earth.
So, what’s the problem?
- The problem is about the sufficiency of God’s grace by Jesus Christ.
- How, exactly, do we become Christians?
The Roman church teaches the equation: “Jesus + good works = merits eternal life.” It teaches that “Jesus + good works = forgiveness, reconciliation, and divine pardon.” Rome’s catechism explains (Art. 2010):
Rome speaks of “initial grace” and “the beginning of conversion.” There is no before and after. There is no bright line in the sand. Salvation is a cooperative process, not a divine event. Moved by the Spirit and by love, we must do good works to “merit for ourselves” the grace needed for eternal life.
This is heresy. It is false. It is wrong.
The truth is that we must trust in Jesus alone for salvation. God declares us to be righteous on the basis of what Jesus has already done. Based on that declaration, God gives his people legal pardon and personal reconciliation. Rome may speak of grace, charity, and conversion, but it means something very different.
Like all false religions, Rome teaches a version of “resume-ism.”
If you don’t believe God exists, then you’re not interested in submitting your resume to God. But, if you do believe he exists, then resume-ism will send you to hell—because it’s wrong.
- You can talk about Jesus all you want, but in the end it’s about you—what you do, what you bring to the table.
- The true faith is about Jesus, what he did, how he rescues you, and how God pardons you and declares you to be righteous if you trust in what Christ did for you.
The apostle Paul is against resume-ism. It’s his obsession. As we parachute into our passage at Romans 3:19-31, we learn from the first portion of the chapter that everyone is a sinner, without exception.
- We’re all in trouble. We’re guilty before the King of the universe.
- God’s old covenant law tells us how his people ought to act.
- But we don’t act like that all the time, or even most of the time.
- Most of us don’t want to act like it either.
So, most people don’t belong to God, because they don’t do what he says, nor do they want to. Now, to our passage.
Righteousness from God
The old covenant law tells God’s people how to live and love him. How to be different, weird, and separate from the world until the Messiah comes. This law speaks to people who are under its authority, “so that every mouth may be silenced and the whole world held accountable to God” (Rom 3:19).
He’s saying the old covenant law silences all excuses and acts as an immovable divine witness to which we are all accountable.
How does this accountability work? Why does it silence us as it confronts us?
Because by means of works of the law (ἐξ ἔργων νόμου) nobody will be declared to be righteous, in God’s sight (Rom 3:20). The word your English bible renders here as “righteous” or “justified” is a legal idea that means moral uprightness. You can’t achieve that by doing the works of the old covenant law—because you’ll keep messing up.
How do we know this? Because the law tells us so, because “through the law we become conscious of our sin” (Rom 3:20).
- The law brings knowledge of sin.
- It tells us we’ll always fall short of the mark—somehow, some way.
- No matter what.
- 100% guaranteed.
This isn’t good, obviously. If God left it there, some people might think he were cruel. But God is not toying with us. The law isn’t about salvation at all. It isn’t there to make us gnaw our fingernails and fear damnation. That’s just resume-ism talking.
- Law-keeping does not earn us salvation. It never did.
- Instead, the old covenant law tells us how to live while we wait for our Rescuer—King Jesus.
- But this “resume-ism” idea had so infected and twisted the popular Jewish understanding of salvation by Paul’s day (and Jesus,’ too) that in many circles it had become the default gateway to a relationship with God.
- Trust in the coming Messiah. Do law-keeping really well. Repeat (see Lk 18:9-14).
But, the apostle Paul says, that’s all wrong. It’s always been wrong. Now, separate from the old covenant law (χωρὶς νόμου), righteousness from God has now been made known—testified to by the law and the prophets (Rom 3:21). Resume-ism has nothing to do with the righteousness from God that’s on the table.
If this righteousness from God—the kind that can never come by means of works of the law—is testified to by the law and the prophets … is it a new thing?
Of course not. This isn’t new. It’s simply the re-presentation of something very old. Rome would do well to listen to Paul. If so, it wouldn’t speak of “meriting for ourselves” the grace needed for eternal life.
- Well, how do you get this righteousness that God is offering? “This righteousness is given through faith in Jesus Christ …” (Rom 3:22). We trust in his faithfulness—that he has been perfect for us, as our delegate and representative.
- Who can have it? Who is eligible? “… to all who believe” (Rom 3:22).
- Why is this righteousness open to anyone? “Because there is no distinction [between people]—everyone sins and therefore lacks God’s glory” (Rom 3:22-23, my trans.).
The phrase often translated as “fallen short of the glory of God” means to be deficient—to be missing or lacking something. Without Jesus, we are each missing the righteousness and holiness and love for God he made us to have. Instead, we sin, so we’re broken, and so we “fall short of” (i.e., lack) God’s glory.
So, how does this righteousness from God happen? Why is it by faith alone and not works?
- Because God declares us to be righteous as a gift, or freely, or gratis (Rom 3:24). This declaration is “on the house.” This means there is no “merit” we bring to the table. Rome is wrong. Dead wrong.
- God issues this declaration to his people by means of his grace, through the liberation (“redemption”) that comes from Christ Jesus (Rom 3:24).
How so?
Well, “God displayed him publicly as the instrument of forgiveness by his shedding of blood, to be received by special faith. God did this to prove his justice because, due to his long-suffering patience, he had let the sins of the past go unpunished” (Rom 3:25, my trans.).
Jesus is the propitiation or sacrifice of atonement or instrument of forgiveness. How so? By means of his death (ἐν τῷ αὐτοῦ αἵματι).
- This is a Federal, representative concept (see Rom 5:12f).
- Like Adam, Jesus is the vicarious representative who acts on behalf of his people. Jesus lives the perfect life we cannot. He dies the criminal death we deserve. He defeats Satan and the curse of death on our behalf. He does this as our Federal representative.
- Jesus takes our sins upon himself in the same manner as an employer that is legally, vicariously responsible for the actions of its employees.
- The difference is, of course, that Jesus does this willingly and lovingly.
How do we receive this righteousness from God that Jesus achieves? By faith (Rom 3:24). Not by works. In fact, Jesus has retroactively paid for all the sins he had forgiven on credit from the old covenant days gone by (Rom 3:25).
God has done this as a demonstration or proof of his righteousness—his justice (Rom 3:26). I recently investigated a case in which adoptive parents sexually and physically tortured their adoptive children for years. It would have been evil if the state had opted to “forgive and forget” this. We instinctively know that. Crime demands punishment. Justice must be done. It’s the same with God, and so Jesus’ life—his death as our vicarious representative—is what satisfies the justice required. That’s why Jesus’ life and death demonstrates or proves that God is just.
And whom does God justify? Who does God declare to be righteous? The one with the best resume? The one who does more than the guy next to him? The one who does the most good works? No—it is “those who have faith in Jesus” (Rom 3:26).
The inevitable result of resume-ism is pride and self-satisfaction. But, because we now know that righteousness is a gift from God separate from works, we know that all boasting is excluded. It is shut out by the law of faith (Rom 3:27). It has nothing to do with being a Christian. “For we maintain that a person is justified by faith apart from the works of the law” (Rom 3:28). This is open to any person. Jew. Gentile. Azeri. Afghani. Japanese. God will declare anyone to be righteousness who trusts in Christ for salvation (Rom 3:29-30; cp. Gal 3:28-29).
This whole thing (righteousness from God by faith alone, in Christ alone—nothing to do with resume-ism) is not new. The new covenant does not rip up and invalidate the old covenant law. Instead, the apostle Paul declares, it upholds it (Rom 3:31) because Jesus teaches us that the law is about how to live as believers, not how to become a believer.
Why being a Protestant matters
It matters because this is about how you become a Christian. Is Jesus’ grace enough to (a) give us permanent, legal pardon, and (b) permanently heal our broken relationship with God? Or do we need to stir in some resume-ism, too? The apostle Paul says that, because we have been justified by faith, we have peace with God through our Lord Jesus Christ (Rom 5:1).
We’re justified by God because we have faith … in what?
- That Jesus died for you.
- That he did it as your vicarious representative, in your place.
- That resume-ism won’t get you there.
- That it can’t get you there.
And so, the equation “Jesus + something else = salvation” is wrong. It will send you to hell, because it can’t get you this righteousness from God (Gal 2:21).
- That means you’re still in trouble, no matter what label you put on yourself.
- It means you don’t have peace with God through our Lord Jesus Christ, because you haven’t yet trusted in him alone for salvation.
- You’re still trying to upload your resume to the website.
But God does not want your resume. He wants you to only trust in what his eternal Son has already done for you. He declares you to be righteousness by means of faith and trust in his Son—nothing else. That is the core issue of the Protestant Reformation, and of the true Christian faith.
