What root of sin is shown in Romans 3:18?
How does Romans 3:18 reveal the root of human sinfulness?

The Verse in Focus

Romans 3:18: “There is no fear of God before their eyes.”


Setting the Scene

• Paul has just finished stringing together Old Testament citations (Romans 3:10-18) to prove that every person—Jew and Gentile alike—is under sin.

• The closing charge, v. 18, acts as the punchline: the fundamental reason for humanity’s downward spiral is a heart that refuses to reverence God.


What “No Fear of God” Means

• Fear here is not mere dread; it is awe, honor, and submission to God’s authority.

• When that awe is absent, every moral boundary collapses.

• Sin is therefore less about ignorance and more about willful disregard for God’s rightful place.


Why the Fear of God Is Foundational

Proverbs 1:7 – “The fear of the LORD is the beginning of knowledge.” No fear, no true knowledge of right and wrong.

Ecclesiastes 12:13 – Fear God and keep His commandments; it sums up our duty.

Isaiah 66:2 – God esteems the one “who is humble and contrite in spirit, and trembles at My word.”


The Chain Reaction When Fear Is Absent

1. Suppression of truth: Romans 1:18 – truth is pushed down because acknowledging it would require honoring God.

2. Darkened reasoning: Romans 1:21 – thinking becomes futile; hearts grow dark.

3. Unrestrained desires: Romans 1:24-32 – God “gives them over” to the very sins they crave.

4. Brazen practice: Psalm 36:1 – “There is no fear of God before his eyes; he flatters himself…” Sin becomes celebrated.


Old Testament Echo

Psalm 36:1 is Paul’s direct source. David noticed that wickedness springs from an internal declaration: “God won’t call me to account.” Romans 3 shows that the same attitude resides in every human heart apart from grace.


The First Sin Revisited

Genesis 3:5 – the serpent entices Eve with a vision of autonomy: “You will be like God.”

• The moment reverential fear is replaced by self-exaltation, the fall happens.

Romans 5:12 ties this rebellion to us all: “just as sin entered the world through one man…”


New Testament Reinforcement

Luke 12:4-5 – Jesus commands His disciples to fear God, who has ultimate authority.

2 Corinthians 7:1 – perfecting holiness happens “in the fear of God.”

Revelation 14:7 – the eternal gospel begins, “Fear God and give Him glory.”


Root Diagnosis

At its core, sin is not merely bad behavior; it is the soul’s refusal to stand in awe of its Creator. Romans 3:18 exposes the taproot: no fear, no obedience—only rebellion.


Walking it Out

• Cultivate daily awe through Scripture, seeing God’s holiness and majesty.

• Remember accountability: Hebrews 4:13 – nothing is hidden from His sight.

• Celebrate grace: through Christ, God instills a new heart that delights to fear Him (Jeremiah 32:40).

• Practice obedience promptly; reverential fear expresses itself in quick submission.


Summary

Romans 3:18 doesn’t just diagnose symptoms; it zeroes in on the disease. When the fear of God vanishes, sin flourishes. Restoring that fear—through the gospel—restores life, wisdom, and holiness.
