Topical Lexicon
Overview of New Testament Usage

The adjective ἰσχυρός (Strong’s Greek 2478) appears twenty-nine times in the New Testament and consistently conveys the idea of exceptional power—whether physical, moral, institutional, angelic, or divine. The contexts fall naturally into several thematic groupings that together enrich a biblical theology of strength and its proper place under the sovereign rule of God.

Physical Power and Natural Forces

Luke 15:14 pictures a “severe famine” that overwhelms the prodigal, reminding readers that earthly scarcity can expose spiritual destitution.
Matthew 14:30 cites a “strong wind” that unsettles Peter; faith falters when the created order appears mightier than the Creator.
Hebrews 11:34 celebrates saints who “became mighty in battle,” yet the surrounding catalogue emphasizes that true valor springs from faith, not mere human prowess.

Human Institutions and Earthly Structures

• Revelation repeatedly calls Babylon “the mighty city” (Revelation 18:2, 10), only to show that her grandeur collapses in an hour. The repeated adjective underscores the moral: no empire is secure against the judgments of the Lord.
2 Corinthians 10:10 records critics who deem Paul’s letters “weighty and forceful,” yet the apostle counters in the same epistle that divine power works through apparent weakness (2 Corinthians 12:9).
1 Corinthians 1:27 sets up the paradox that God chooses the weak to shame the “strong,” overturning worldly metrics of importance.

Divine Strength and Angelic Might

• Mighty angels appear at critical junctures: proclaiming the worthiness of the Lamb (Revelation 5:2), revealing judgment (Revelation 10:1), and executing it (Revelation 18:21). Their strength is delegated, serving the purposes of the Almighty.
Revelation 18:8 grounds Babylon’s downfall in this affirmation: “for mighty is the Lord God who judges her.” Earthly power disintegrates before the eternal omnipotence of God.

Christ, the Stronger One

John the Baptist points beyond himself to “One more powerful than I” (Matthew 3:11; Mark 1:7; Luke 3:16). Jesus embodies ἰσχυρός in absolute terms—He is the King who binds the “strong man” (Matthew 12:29; Mark 3:27; Luke 11:21-22) and liberates the captives. His miracles, exorcisms, cross, and resurrection manifest a strength that conquers sin, death, and Satan.

The Gospel’s Paradox: Weakness Shaming the Strong

1 Corinthians 1:25-27 contrasts human and divine strength: “the weakness of God is stronger than man’s strength” (1 Corinthians 1:25). Paul revisits the theme in 1 Corinthians 4:10, conceding that apostles appear weak while the Corinthians regard themselves as strong—an ironic critique that urges humility. The same epistle warns, “Are we stronger than He?” (1 Corinthians 10:22), dismissing any notion that human resolve can outmuscle divine prerogative.

Spiritual Vigor in the Believer

Hebrews 6:18 offers “strong encouragement” rooted in God’s unchangeable oath, fortifying persecuted believers.
1 John 2:14 commends young men who “are strong, and the word of God abides in you,” linking spiritual stamina to Scripture’s indwelling presence.
Hebrews 5:7 portrays Jesus praying “with loud cries,” showing that earnest intercession is a channel for holy strength.

Prophetic Declarations of Final Judgment

The repeated adjective in Revelation 19:6 (“mighty thunder”) and 19:18 (“the flesh of kings, generals, and mighty men”) frames the eschaton as a theatre where every competing power is subdued beneath the reign of the Lord God Almighty.

Pastoral and Ministry Implications

1. Confidence: God’s strength guarantees the efficacy of His promises (Hebrews 6:18).
2. Humility: Human accomplishment, status, or ability must yield to the superior might of the cross (1 Corinthians 1:25-27).
3. Warfare: Spiritual conflict is real, but victory belongs to the “stronger” Christ who has already overcome (Luke 11:22).
4. Encouragement: Believers draw vigor from Scripture and prayer, not from self-reliance (1 John 2:14; Hebrews 5:7).
5. Mission: Paul’s example (2 Corinthians 10:10) assures ministers that divine potency often hides beneath outward frailty.

Summary

Ἰσχυρός threads through the New Testament as a reminder that genuine power is God’s alone. Whether depicting storms, empires, angels, or the Savior Himself, each occurrence feeds a unified testimony: “For the Lord our God, the Almighty, reigns” (Revelation 19:6). Those who trust Him may stand assured that His strength is both the ground of their salvation and the measure by which all other might is judged.
