Paul’s Systematic Explanation of Salvation, Justification, and Sanctification.

THE POWER OF THE GOSPEL:

Righteousness by Faith Alone

Lesson 46 of 66: The Book of Romans

The Revelation of Righteousness: The Gospel of God

The Book of Romans is the Apostle Paul’s masterpiece, often considered the most important theological treatise ever written. Paul wrote this letter to the church in Rome (which he had not yet visited) to introduce himself and to systematically lay out the complete meaning of the Gospel—the good news of Jesus Christ.

The central theme of the entire book is found early in the letter: "For I am not ashamed of the gospel, for it is the power of God for salvation to everyone who believes, to the Jew first and also to the Greek. For in it the righteousness of God is revealed from faith for faith, as it is written, 'The righteous shall live by faith.'" (Romans 1:16–17)

I. The Need for Righteousness (Chapters 1–3)

Paul first establishes the essential foundation for salvation: all humanity is condemned before a holy God.

  • The Sin of All People: Paul argues that both the Gentiles (those outside the Law) and the Jews (those under the Law) are utterly sinful. Gentiles are guilty because they rejected the obvious truth revealed in creation, while Jews are guilty because they failed to keep the Law they were given.

  • Universal Condemnation: Paul concludes this section with a devastating summary: “For all have sinned and fall short of the glory of God.” (Romans 3:23) This makes it clear that no one can earn salvation or achieve righteousness on their own merits.

II. The Provision of Righteousness (Chapters 3–8)

Having established humanity’s desperate need, Paul reveals God's perfect solution through Christ.

  • Justification by Faith: Justification is the key word here. It means being declared righteous by God. Paul asserts that this righteousness is received "apart from the law" and is granted solely through faith in Jesus Christ. We are saved not by what we do, but by what Christ did: “we are justified by faith apart from works of the law.” (Romans 3:28)

  • Peace and Assurance: Paul uses Abraham as the ultimate example, noting that he was credited as righteous simply because he believed God's promise. Because we are justified, we have peace with God and absolute assurance of our salvation through the Holy Spirit.

  • Sanctification: Chapter 6 introduces sanctification—the process of becoming holy. The Christian is "dead to sin" but "alive to God in Christ Jesus" (Romans 6:11). This new life is empowered by the Holy Spirit (Chapter 8), who enables us to live righteously and guarantees our future resurrection.

III. God’s Sovereign Plan for Israel (Chapters 9–11)

Paul pauses to address God’s plan for Israel, explaining why the majority of Jews have rejected Jesus as the Messiah.

  • God’s Unchanging Promise: Paul affirms that God has not abandoned Israel; His promises are still true. God has sovereignly allowed Israel's temporary rejection of Christ to bring salvation to the Gentiles.

  • The Future Hope: The book promises that one day, a remnant of Israel will be saved, culminating in a future spiritual restoration: “a partial hardening has come upon Israel, until the fullness of the Gentiles has come in. And in this way all Israel will be saved.” (Romans 11:25–26)

IV. The Practice of Righteousness (Chapters 12–16)

The final section is a powerful instruction on how justified believers should live their lives—this is where theology becomes practical action.

  • Living Sacrifice: Paul calls us to be "living sacrifices," transforming our minds so we can serve others with genuine love and humility (Romans 12:1–2).

  • Love and Submission: Christians are instructed on how to live in the community—using spiritual gifts, loving enemies, and submitting to governing authorities.

  • Caring for the Weak: Paul strongly emphasizes unity, instructing believers to be sensitive to those whose consciences are weaker in matters that are non-essential, all for the sake of unity and glorifying God.

Applying the Truth Today

Romans is an essential guide to understanding the heart of the Christian faith. It assures us that our salvation is totally secure because it rests not on our own fickle performance, but on the finished work of Christ. It challenges us to live out our justification by allowing the Holy Spirit to continually sanctify us, leading to a life characterized by humble, active love and submission to God's will.

Reflection Questions for Your Journey:

  1. Justification by Faith. If you were asked how you get into heaven, would your answer rely on your actions or solely on your faith in Christ's finished work? How does Romans 3:28 secure your hope?

  2. Living Sacrifice. What does it mean for your daily routine to present your body as a "living sacrifice"? What specific habit or activity do you need to stop to renew your mind?

  3. Sanctification. How are you currently cooperating with the Holy Spirit (Chapter 8) in the process of sanctification—the journey of becoming more like Christ?
