Isaiah 36:15: Faith vs. Fear Theme?
How does Isaiah 36:15 reflect the theme of faith versus fear?

Canonical Text and Translation

“Do not let Hezekiah persuade you to trust in the LORD when he says: ‘The LORD will surely deliver us; this city will not be handed over to the king of Assyria.’ ” (Isaiah 36:15)


Historical Setting: The Assyrian Crisis of 701 BC

Isaiah 36 records the Assyrian assault under Sennacherib against Judah. By 701 BC, Assyria had already crushed Samaria (722 BC) and subdued forty-six fortified Judean towns (cf. Taylor Prism, British Museum). Only Jerusalem remained. The Rabshakeh—Sennacherib’s chief envoy—stood outside the city walls, speaking Judean so the common people could hear. His speech blends intimidation with theological ridicule, aiming to dismantle Hezekiah’s faith and replace it with paralyzing fear.


Literary Context within Isaiah 36–39

Chapters 1–35 contain prophetic oracles, while 36–39 shift to narrative, providing a living case study of faith versus fear. Isaiah 36:15 sits at the center of Rabshakeh’s taunt (vv. 4-20). His rhetoric directly contradicts Isaiah’s earlier calls to “trust in the Holy One of Israel” (Isaiah 30:15). The tension heightens: whom will Jerusalem believe—Yahweh or Assyria?


Faith versus Fear: Theological Theme

1. Fear weaponizes visible power; faith relies on the unseen but covenantally faithful God (Isaiah 7:9; 2 Corinthians 5:7).

2. Fear magnifies circumstances; faith magnifies God (Psalm 46:1-3, written in this era).

3. Fear demands surrender to worldly masters; faith rests in Yahweh’s sovereignty (Isaiah 37:16).

Rabshakeh’s line “Do not let Hezekiah persuade you to trust in the LORD” unmasks the contest. Hezekiah’s policy (37:14-20) is prayerful dependence; Assyria’s policy is psychological warfare.


Psychology of Fear and Propaganda

Modern behavioral science notes that fear messages succeed when: (a) threat is severe, (b) audience feels powerless, (c) an alternative authority offers safety. Rabshakeh hits each point: Assyria’s conquests (severe), Jerusalem’s smallness (powerless), Assyrian clemency upon surrender (safety). Yet biblical faith supplies an even greater authority and a promise of deliverance, breaking fear’s grip (1 John 4:18).


Contrast With Hezekiah’s Prayer and God’s Deliverance

Isaiah 37 records Hezekiah spreading Rabshakeh’s letter “before the LORD” (v. 14). Faith pivots from human speech to divine response. God answers: “I will defend this city to save it” (37:35). That night the Angel of the LORD strikes 185,000 Assyrians (37:36). Archaeologically, Sennacherib’s annals conspicuously omit Jerusalem’s capture, admitting only that he “shut up Hezekiah… like a bird in a cage.” The deliverance validates faith and exposes fear’s lie.


New Testament Parallels and Fulfillment

Jesus echoes Isaiah’s theme: “Do not fear those who kill the body” (Matthew 10:28). The ultimate deliverance arrives in Christ’s resurrection (1 Corinthians 15:54-57). Just as Hezekiah trusted in Yahweh’s power over Assyria, believers trust in Christ’s victory over sin and death.


Archaeological Corroboration

• Taylor Prism & Chicago Prism: list of conquered Judean cities, corroborating Isaiah 36–37 timelines.

• Lachish Reliefs (British Museum): stone panels from Sennacherib’s palace depicting the siege of Lachish, affirming the Assyrian advance described in Isaiah 36:1-2.

• Hezekiah’s Tunnel inscription (Silwan): attests to Hezekiah’s water-security preparations (2 Kings 20:20), underscoring the historical backdrop of impending siege and the logic of either faith in God or fear of deprivation.


Applications for Believers Today

1. Evaluate voices: modern “Rabshakehs”—media, culture, academia—still say, “Do not let faith persuade you.” We must discern.

2. Respond with prayer: spread anxieties “before the LORD” (Philippians 4:6-7).

3. Recall past deliverances: archaeology, manuscript preservation, and Christ’s empty tomb supply evidential anchors that feed faith, not fear.

4. Act in obedience: Hezekiah’s reforms (2 Kings 18:3-6) show that faith that conquers fear expresses itself in concrete holiness.


Conclusion

Isaiah 36:15 crystallizes the age-old contest: trust in God or succumb to fear. History, text, and fulfilled prophecy converge to vindicate faith. The same Lord who routed Assyria and rose from the grave calls every generation to turn from dread and rest in His unassailable power.
