What does Romans 5 teach about the relationship between sin and grace?

In Romans 5, Paul poignantly contrasts the effects of Adam's sin with the redemptive work of Christ. He asserts that through one man's disobedience, many were made sinners; however, through one man's obedience—referring to Christ—many will be made righteous. This illustrates a pivotal theological truth: sin may have brought death, but grace provided through Jesus ensures life and hope for believers. Romans 5:21 encapsulates this by stating that as sin reigned in death, grace reigns through righteousness resulting in eternal life. Therefore, the relationship underscores that grace is superior and transformative, countering the effects of sin.
