Does divine hardening negate free will?
Does God hardening hearts contradict free will?

HARDENING OF THE HEART AND HUMAN FREEDOM (Exodus 10:20)


Key Text

“But the LORD hardened Pharaoh’s heart, and he would not let the Israelites go.” (Exodus 10:20)


I. Defining “Hardening” In The Old Testament

Three Hebrew verbs appear in the Exodus narratives:

• ḥāzaq (חָזַק) – “to strengthen, make firm.”

• kāḇēd (כָּבֵד) – “to make heavy, dull.”

• qāšâ (קָשָׁה) – “to make stubborn, severe.”

Combined, they describe a heart rendered obstinate, not by removal of choice, but by reinforcement of a pre-existing disposition. Ancient Semitic idiom routinely ascribes ultimate causality to God for events He permits (cf. Job 1:21; Amos 3:6).


Ii. Textual Distribution Of Agency In Exodus 4–14

Self-hardening: 7:13; 7:22; 8:15; 8:32; 9:7; 9:34; 1 Samuel 6:6 (retrospective).

Divine prediction: 4:21; 7:3; 14:4.

Divine hardening realized: 9:12; 10:20; 10:27; 11:10; 14:8.

The narrative alternates: Pharaoh first hardens himself (8:15) before God judicially confirms that posture (9:12). This literary pattern safeguards moral responsibility while highlighting divine sovereignty.


Iii. The Hebraic Principle Of Concurrent Causation

Scripture presents dual agency without contradiction. Joseph declares, “You planned evil against me, but God planned it for good” (Genesis 50:20). The crucifixion—“by God’s set purpose and foreknowledge” yet executed “by the hands of the lawless” (Acts 2:23)—exemplifies the same compatibilism. Human volition operates genuinely within the parameters of God’s overarching decree.


Iv. Philosophical Coherence: Free Will Under Sovereignty

1. Libertarian freedom (ability to choose A or not-A) is unnecessary for moral accountability; what is required is freedom from external coercion of one’s own desires.

2. Pharaoh acts according to his strongest inclination—retaining Israelite labor. Divine hardening does not implant new evil; it withdraws restraining grace (Romans 1:24–28), allowing existing corruption to solidify.

3. Such compatibilism avoids determinism (which denies genuine choice) and indeterminism (which renders choice random).


V. Theological Motive: Displaying God’S Glory

“For this very purpose I have raised you up, that I might display My power in you, and that My name might be proclaimed in all the earth” (Romans 9:17 quoting Exodus 9:16). Judgment upon Egypt showcased divine supremacy over its deities (Numbers 33:4) and prepared the typological canvas for redemption by the Passover Lamb (Exodus 12; 1 Corinthians 5:7).


Vi. Archaeological And Historical Corroboration

• The Ipuwer Papyrus (Leiden 344) laments Nile bloodshed, darkness, and the death of the firstborn—parallels to the plagues that hardening precipitated.

• Merneptah Stele (c. 1208 BC) confirms an Israelite presence in Canaan soon after a plausible Exodus window.

• Karnak reliefs depict Pharaohs claiming divine empowerment for obstinacy against enemies—mirroring the biblical motif of a king whose heart is “a stream of water in the hand of the LORD” (Proverbs 21:1).


Vii. New Testament Confirmation

John 12:39-40 cites Isaiah 6:10 to explain unbelief among those who witnessed Christ’s signs: “‘He has blinded their eyes and hardened their hearts…’” Yet verse 42 immediately records many believing rulers—free response persists beneath divine judicial action.


Viii. Pastoral Implications

1. Warning: A repeated refusal of light invites judicial hardening (Hebrews 3:7-15).

2. Hope: God also “opens the heart” (Acts 16:14). Prayer and proclamation remain vital means ordained to overcome rebellion (2 Corinthians 4:4-6).

3. Humility: Believers credit grace alone for any softening (Ezekiel 36:26).


Ix. Conclusion

Exodus 10:20 does not negate free will; it illustrates that God’s sovereign governance and human choices operate concurrently. Pharaoh chooses according to his corrupt nature; God magnifies His glory by permitting—and then fortifying—that choice for redemptive-historical ends. The text upholds both moral responsibility and divine prerogative without contradiction, inviting every reader to “Today, if you hear His voice, do not harden your hearts.” (Hebrews 3:15)
