According to Romans 5:12, how did sin enter the world?

The explanation for why sin entered the world as described in Romans 5:12 highlights a significant theological concept concerning the nature of sin and its consequences. The verse states that sin entered the world "through one man," referring to Adam, whose disobedience in the Garden of Eden is traditionally understood to have initiated a fall from grace. This event is pivotal in Christian theology, as it establishes the belief that humanity inherited a sinful nature due to this original sin.

The phrase "leading to death spreading to all men" underscores the universality of this consequence; essentially, it indicates that as a result of Adam's sin, death and sin became pervasive within humanity. This reflects the doctrine of original sin, indicating that every human being is affected by Adam's transgression, thus requiring redemption through Christ.

By focusing on this singular event, the verse emphasizes the direct lineage of sin entering the world and awakens a need for understanding salvation. It is not contradicted by the nature of societal norms, natural disasters, or the actions of multiple prophets, as those do not align with the specific narrative of humanity's fall and need for salvation established in the apostolic teaching of Paul.
