Romans 2:15: God's law on our hearts?
How does Romans 2:15 reveal God's law written on our hearts?

Romans 2 : 15

“…since they show that the work of the Law is written on their hearts, their consciences also bearing witness, and their thoughts either accusing or defending them.”

Core truth

- God Himself has engraved His moral standard inside every person’s inner being; no one is born morally neutral or blank.

The phrase “written on their hearts”

- “Written” points to a finished, deliberate act—God placed His Law there.

- “Hearts” in Scripture refers to the whole inner person—mind, will, emotions—so the Law reaches every facet of life.

Evidence of the inscription

- Conscience: an internal courtroom where we “hear” the Law; it testifies for or against us.

- Inner dialogue: our thoughts “accuse or defend,” proving that we already know right from wrong even apart from the written Torah.

How Romans 2 : 15 links with the rest of Scripture

- Jeremiah 31 : 33; Ezekiel 36 : 26-27 – God promises to write His Law on hearts, fulfilled ultimately in the new covenant.

- 2 Corinthians 3 : 3 – The Spirit now writes not on stone but on “tablets of human hearts.”

- Hebrews 8 : 10 – Echoes Jeremiah, showing continuity between Old and New Covenants.

- John 1 : 9 – Christ, the true Light, “gives light to everyone,” aligning with the universal witness of conscience.

What this means for believers

- We can appeal to the conscience of every person when sharing the gospel; the Law already resonates inside them (Acts 24 : 16).

- Our own renewed hearts can now obey from the inside out, not by external pressure (Romans 6 : 17).

- Sensitivity matters: a clean conscience is maintained by quick repentance and obedience (1 Peter 3 : 16; 1 John 1 : 9).

Practical takeaways

1. Acknowledge the Law within: pay attention when conscience flags sin or affirms righteousness.

2. Use Scripture to sharpen that inner voice; the written Word clarifies what conscience senses.

3. Share the gospel confidently, knowing every heart already bears a faint imprint of God’s standards.
