What does Romans 3 teach about sin?

In Romans 3, Paul articulates the universality of sin, stating that there is none righteous, no, not one (Romans 3:10). He emphasizes that all human beings, regardless of their background, are under sin and cannot claim any righteousness before God. This stark reality is essential, as it sets the stage for understanding the necessity of grace and the gospel. By highlighting the depth of our sinfulness, Paul makes clear that it is only through faith in Jesus Christ that we can attain righteousness. The overarching message is that acknowledgment of sin leads to the recognition of our need for a Savior and the incredible gift of justification offered through Christ.
