Compare Isaiah 3:9 with Romans 1:32 on the acknowledgment of sin.

Texts in Focus

Isaiah 3:9: “The expression on their faces testifies against them, and like Sodom they flaunt their sin; they do not conceal it. Woe to them, for they have brought disaster upon themselves.”

Romans 1:32: “Although they know God’s righteous decree that those who do such things are worthy of death, they not only continue to do these things, but also approve of those who practice them.”


Key Observations from Isaiah 3:9

• Outward countenance gives away inward rebellion—sin is no longer hidden.

• The comparison to Sodom highlights shamelessness (cf. Genesis 19:5).

• Refusal to conceal wrongdoing indicates a hardened heart.

• A divine “woe” signals certain judgment; disaster is self-inflicted (cf. Proverbs 6:32).


Key Observations from Romans 1:32

• The people possess moral awareness: they “know God’s righteous decree.”

• Knowledge does not restrain behavior; sin is practiced knowingly (cf. James 4:17).

• Approval of others’ sin adds a communal dimension—corruption is celebrated.

• Worthiness of death (cf. Romans 6:23) underscores the seriousness of rebellion.


Shared Themes

• Conscious recognition of God’s standards—yet deliberate refusal to submit.

• Public, even proud, endorsement of ungodliness.

• Sin that moves from private indulgence to public display invites intensified judgment (cf. Hosea 4:1-3).

• Accountability rests on knowledge: greater light brings greater responsibility (Luke 12:47-48).


Progression of Revelation

• Isaiah exposes brazen sin in Judah’s society, warning of impending national calamity.

• Paul broadens the indictment to the Gentile world, revealing a universal pattern when truth is suppressed (Romans 1:18).

• Together, the passages trace a consistent biblical trajectory: awareness → flaunting → judgment.


Consequences of Open Sin

• Internal: seared conscience (1 Timothy 4:2) and spiritual blindness (2 Corinthians 4:4).

• Social: corporate approval multiplies evil, eroding moral order (Micah 7:3-4).

• Divine: certain, righteous judgment—temporal and eternal (Hebrews 10:26-27).


Implications for Believers Today

• Guard the heart against celebrating what God condemns.

• Maintain a tender conscience; swift repentance keeps sin from becoming public spectacle (Proverbs 28:13; 1 John 1:9).

• Counter cultural applause for sin by living and speaking truth in love (Ephesians 4:15).

• Remember that knowledge of God’s decree demands obedience, not mere acknowledgment (John 14:15).
