Which chapter in Romans discusses God's righteousness revealing salvation for both Jews and Gentiles?

The chapters that discuss God's righteousness revealing salvation for both Jews and Gentiles are Chapters 1-3 of Romans. In this section, the Apostle Paul lays the groundwork for his argument about sin and the universality of the need for salvation. He emphasizes that both Jews and Gentiles are under sin and therefore in need of God's mercy through faith in Jesus Christ. This sets the stage for understanding that salvation is accessible to everyone, regardless of their background.

While Chapters 8-11 and 12-15 deal with deeper aspects of salvation, the roles of Israel, and practical living in light of salvation, the foundational teaching about the righteousness of God and its implications for all humanity is clearly established in the first three chapters. Thus, those chapters are crucial for understanding how Paul articulates the inclusive nature of God's salvation plan.
