Paul's introduction emphasizes his calling as apostle to the Gentiles while declaring the gospel as God's power for salvation to everyone who believes, both Jew and Greek. His description of God's wrath against human ungodliness reveals how rejecting divine revelation in creation leads to moral and spiritual corruption through idolatry. The catalog of sins resulting from suppressing truth demonstrates how abandoning God produces both individual and social decay, setting up humanity's universal need for divine salvation.
