Link Jer. 6:28 & Rom. 3:23 on sin.
How does Jeremiah 6:28 connect with Romans 3:23 about human sinfulness?

Setting the Stage

Jeremiah and Paul wrote centuries apart, yet they speak with one voice about the depth of humanity’s sin problem. Jeremiah paints a gritty snapshot of Judah’s rebellion; Paul universalizes the diagnosis to every human heart.


Jeremiah 6:28 — Old Testament Snapshot

“ ‘They are all hardened rebels, walking around as slanderers. They are bronze and iron; all of them are corrupt.’ ”

• “Hardened rebels” – not occasional slip-ups but entrenched resistance against God.

• “Walking around as slanderers” – sin expressed in daily speech and relationships.

• “Bronze and iron” – imagery of stubborn, unyielding metal; hearts that will not bend to God (cf. Zechariah 7:11-12).

• “All of them are corrupt” – no exception clause, no righteous remnant on their own merits.


Romans 3:23 — New Testament Confirmation

“for all have sinned and fall short of the glory of God,”

• “All” ‑ the indictment stretches beyond Judah to every nation and every generation.

• “Sinned” – misses God’s perfect mark (Greek hamartanō).

• “Fall short of the glory” – the loss of God-reflecting purpose seen since Eden (Genesis 3:7-19).


Threads That Tie the Verses Together

• Universality of Sin

– Jeremiah: “all of them.”

– Romans: “all have sinned.”

• Depth of Corruption

– Jeremiah’s “bronze and iron” signals deeply ingrained hardness.

– Romans emphasizes an ongoing state: “fall short,” present tense, a continuing deficiency.

• Moral and Relational Breakdown

– Slander in Jeremiah reveals horizontal fallout.

– Falling short of God’s glory in Romans underscores vertical rupture with the Creator.

• Continuity of Revelation

– Jeremiah exposes the Old Covenant community’s failure; Paul shows that the New Covenant’s need is identical apart from Christ (cf. Romans 3:10-12 quoting Psalm 14:2-3).


Wider Biblical Echoes

Genesis 6:5 – pervasive evil “all day long.”

Isaiah 64:6 – “all our righteous acts are like filthy rags.”

Ephesians 2:1-3 – “dead in trespasses and sins… by nature children of wrath.”

1 John 1:8 – “If we say we have no sin, we deceive ourselves.”


Implications for Us Today

• Sin is not merely external behavior; it is internal hardness that resists God’s authority.

• No cultural, religious, or moral pedigree exempts anyone—Jeremiah’s covenant people and Paul’s entire world stand equally guilty.

• Honest acknowledgment of sin prepares the heart for the gospel (Proverbs 28:13; Romans 3:24-26).


Hope Beyond the Diagnosis

Jeremiah will later promise a new covenant with transformed hearts (Jeremiah 31:31-34). Paul unveils its fulfillment in Christ: “But now, apart from the Law, the righteousness of God has been revealed” (Romans 3:21). The God who exposes universal sin also provides a universal Savior (John 3:16), exchanging bronze hearts for hearts of flesh (Ezekiel 36:26).

What actions can we take to avoid becoming 'rebellious' as in Jeremiah 6:28?
