In a recent teaching session, we explored Romans 5:12, a verse that serves as a gateway to understanding the pervasive nature of sin and the transformative power of justification by faith. Paul’s message emphasizes the solution to sin through Jesus Christ, highlighting the benefits of justification by faith, such as peace, joy, and assurance of salvation. We examined the logical structure of the verse, noting its use of syllogism and chiasmus to contrast Adam’s transgression with Christ’s redemptive work. The discussion also addressed the broader implications of sin and death, while underscoring the comprehensive remedy offered by Christ.
