One of the most penetrating insights in all of Paul’s letters is found in Romans 10:2–3:

“For I testify about them that they have a zeal for God, but not in accordance with knowledge. For not knowing about the righteousness of God and seeking to establish their own, they did not subject themselves to the righteousness of God.”

Here Paul addresses his fellow Israelites, the Jewish nation, who possessed genuine zeal and devotion to religious practice but lacked the true knowledge that leads to salvation. They were passionate, moral, and outwardly devout, yet they missed Christ. In their efforts to establish their own righteousness through works of the Law, they rejected the righteousness that comes only through faith in Jesus Christ.

This passage is not merely a historical critique of first-century Israel. It is a timeless warning to all who substitute religious zeal or humanitarian passion for the saving knowledge of Christ. Today, we see the same error repeated in the form of the social gospel—a misguided zeal that pursues charity, justice, and good works without the foundation of truth in Christ crucified and risen.

Zeal Without Knowledge

Paul does not deny that Israel had zeal. The Greek word zelos conveys fervor, ardor, enthusiasm, even jealousy. Israel’s zeal was evident in their devotion to the Law, their religious traditions, their synagogue life, and their moral seriousness. Yet zeal by itself is not saving. Zeal can be blind.

Paul qualifies their zeal with the phrase “not in accordance with knowledge.” The Greek word epignōsis means a full, accurate, relational knowledge of God. Israel’s zeal was not rooted in the truth of God’s revelation in Christ. They had information from the Law and the Prophets, but they failed to recognize that all pointed to the Messiah. Thus their zeal became misdirected energy, leading them away from salvation rather than toward it.

Zeal without knowledge is like a blazing fire without control—it has power but no direction, intensity but no truth. Israel’s zeal drove them to establish their own system of righteousness, to add layers of tradition to the Law, and to pursue works of merit. But zeal without the truth of Christ is spiritual blindness.

The Righteousness of God Versus Self-Righteousness

In verse 3 Paul explains the tragic result: “For not knowing about the righteousness of God and seeking to establish their own, they did not subject themselves to the righteousness of God.”

The “righteousness of God” is the righteousness that comes by faith in Christ, as Paul had already explained in Romans 3:21–22: “But now apart from the Law the righteousness of God has been manifested… even the righteousness of God through faith in Jesus Christ for all those who believe.”

Israel missed this because they clung to their own self-righteousness. They sought to “establish their own” system of acceptance with God through Law-keeping. In doing so, they rejected the righteousness that God freely gives to those who believe in Christ.

This is the essence of misplaced zeal: pursuing God on one’s own terms rather than submitting to His revealed way of salvation. No matter how fervent, sincere, or passionate, zeal apart from Christ is empty and damning.

Modern Parallels: The Social Gospel as Misguided Zeal

What Paul identified in first-century Israel is mirrored today in the modern distortion of Christianity known as the social gospel. Many churches and individuals display great zeal for humanitarian causes. They feed the poor, clothe the needy, march for justice, and engage in activism with impressive energy. Yet this zeal often lacks the foundation of true knowledge of the gospel.

Like Israel of old, they are “not knowing about the righteousness of God.” They confuse external works with spiritual life. They believe that by doing good works for society they are advancing the kingdom of God. In reality, they are establishing their own righteousness—a system of moral achievement that cannot save.

Zeal for the poor, zeal for social justice, zeal for humanitarian aid—when divorced from the knowledge of Christ and His atoning work—is zeal without knowledge. It is well-intentioned but eternally misguided. Just as Israel’s zeal did not bring them to salvation, so too modern social gospel zeal cannot reconcile anyone to God.

Paul’s Own Zeal Before Conversion

Paul himself is the ultimate example of misguided zeal. Before his conversion, he was a Pharisee of Pharisees, zealous for the Law, persecuting the church, advancing in Judaism beyond his peers (Philippians 3:5–6; Galatians 1:13–14). His zeal was unmatched, but it was zeal without knowledge. It was only when Christ confronted him on the Damascus road that his zeal was redirected toward the truth.

This personal testimony underscores Paul’s point. Zeal, no matter how intense, cannot save apart from Christ. Paul’s life shows that salvation comes not through passion for religion or good works, but through the knowledge of Jesus Christ as Lord and Savior.

The Danger of Misguided Zeal in the Church

The church today must take Paul’s warning seriously. Zeal can easily be misplaced. Churches can become more passionate about community service than about preaching the Word. They can be more zealous for social reform than for making disciples. They can measure their success by how many meals they serve rather than how many souls they lead to Christ.

This is zeal without knowledge. It is energy misdirected away from the gospel. The true church must never confuse fruit with root, works with salvation, or zeal with truth. The righteousness of God comes only through faith in Christ. Works of mercy are important, but they flow from salvation—they do not constitute it.

Submitting to the Righteousness of God

The key phrase in Romans 10:3 is that Israel “did not subject themselves to the righteousness of God.” Salvation requires submission, humility, and surrender. One must abandon all attempts to establish personal righteousness and receive the righteousness of Christ as a free gift.

This remains the dividing line today. The self-righteous person—whether the devout Pharisee or the modern humanitarian—refuses to bow before Christ. They prefer to build their own system of righteousness. But the believer submits, acknowledging that salvation is by grace alone through faith alone in Christ alone.

Application to Today’s Church

Paul’s rebuke of misguided zeal speaks powerfully to our age. The church must guard against replacing evangelism with philanthropy. Feeding the hungry, housing the homeless, and pursuing justice are good works, but they are not the gospel. The true mission of the church is to proclaim Christ crucified and risen, calling all to repentance and faith.

We must beware of zeal without knowledge—of pouring our energy into causes that make us look righteous but do not lead people to the righteousness of God in Christ. We must refuse to establish our own righteousness through works and instead submit to the righteousness God freely offers in His Son.

Conclusion

Paul’s words in Romans 10:2–3 expose the futility of zeal without knowledge. Israel had passion but missed Christ. Paul himself had zeal but was blind until Christ opened his eyes. Modern humanitarian zeal, no matter how well-meaning, is equally misguided if it is not rooted in the saving knowledge of Christ.

The lesson is clear: zeal must be grounded in truth. Works must flow from faith. Righteousness must be received, not achieved. The church must not replace the gospel with the social gospel. Like Paul, we must proclaim that salvation is not by works but by faith in Christ, and call all people to submit to the righteousness of God.
