Exploring the Meaning of Endeiknumi in Greek

ἐνδείκνυμι means “to show.” In the New Testament it appears in contexts where something inward becomes evident, where God makes an aspect of his action known, and where believers are urged to make qualities plainly visible in conduct.

Occurrences

Romans 2:15: “in that they show the work of the law written in their hearts, their conscience testifying with them, and their thoughts among themselves accusing or else excusing them)”

Here “show” is tied to moral awareness: what is “written in their hearts” becomes manifest in observable ways. The verse locates the showing in an interplay of inner witness (“their conscience testifying”) and inner deliberation (“their thoughts… accusing or else excusing”). ἐνδείκνυμι describes the movement from inward inscription to outwardly demonstrable reality.

Romans 9:17: “For the Scripture says to Pharaoh, “For this very purpose I caused you to be raised up, that I might show in you my power, and that my name might be proclaimed in all the earth.””

“Show” is God’s stated purpose within the situation of Pharaoh. The showing is not abstract: it is “in you,” with Pharaoh as the arena in which divine power is made evident. The result clause (“that my name might be proclaimed in all the earth”) frames ἐνδείκνυμι as a showing that carries public consequences—what is shown becomes speakable and spread.

Romans 9:22: “What if God, willing to show his wrath and to make his power known, endured with much patience vessels of wrath prepared for destruction,”

In this rhetorical question, ἐνδείκνυμι is paired with God’s resolve: he is “willing to show his wrath.” The verse also connects showing with disclosure (“to make his power known”) and with divine patience (“endured with much patience”). The showing is therefore situated within restraint and endurance, not only within immediate action.

2 Corinthians 8:24: “Therefore show the proof of your love to them before the assemblies, and of our boasting on your behalf.”

“Show” functions as an imperative directed to the community: love is to be exhibited as “proof,” and it is to be done “before the assemblies.” The public setting matters; ἐνδείκνυμι calls for conduct that makes love verifiable to others, confirming what has been claimed (“our boasting on your behalf”).

Ephesians 2:7: “that in the ages to come he might show the exceeding riches of his grace in kindness toward us in Christ Jesus;”

Here God is the one who shows, and the time frame is extended (“in the ages to come”). What is shown is described in layered terms—“the exceeding riches of his grace”—and the manner of showing is “in kindness toward us in Christ Jesus.” ἐνδείκνυμι thus operates in a forward-looking horizon where divine generosity is set on display through beneficent action.

1 Timothy 1:16: “However, for this cause I obtained mercy, that in me first, Jesus Christ might display all his patience for an example of those who were going to believe in him for eternal life.”

Although translated “display,” the verb expresses “show” in a personal, exemplary register. The showing occurs “in me first,” with Paul’s experience of mercy serving as the setting. What is shown is “all his patience,” and the purpose is pedagogical: it becomes “an example” oriented toward future believers. ἐνδείκνυμι here is showing that instructs by making a trait visible in a concrete life.

2 Timothy 4:14: “Alexander, the coppersmith, did much evil to me. The Lord will repay him according to his deeds,”

In this sentence, the focus is on “deeds” and recompense: actions are the relevant evidence by which repayment is measured. Within the thought-world of the verse, “show” belongs to the realm of demonstrated behavior—what a person has done stands as what has been made evident, and it is that manifested record that is in view when repayment is expected.

Titus 2:10: “not stealing, but showing all good fidelity, that they may adorn the doctrine of God, our Savior, in all things.”

“Showing” names a visible pattern of integrity set against a contrary practice (“not stealing”). The object is expansive—“all good fidelity”—and the outcome is reputational and communal: such conduct “may adorn the doctrine of God.” ἐνδείκνυμι connects inner trustworthiness with outward behavior that makes a teaching attractive by consistent practice.

Titus 3:2: “to speak evil of no one, not to be contentious, to be gentle, showing all humility toward all men.”

The verb appears in a list of social virtues, and “showing” attaches specifically to humility. Humility is not treated as a private sentiment but as something enacted “toward all men,” alongside speech discipline (“speak evil of no one”), restraint (“not… contentious”), and gentleness. ἐνδείκνυμι highlights humility as a quality made perceptible in relational conduct.

Hebrews 6:10: “For God is not unrighteous, so as to forget your work and the labor of love which you showed toward his name, in that you served the saints, and still do serve them.”

“Showed” looks back on a demonstrated “labor of love,” and the verse specifies how it was shown: “in that you served the saints, and still do serve them.” The showing is therefore concrete service, continuing into the present. The phrase “toward his name” links the visible act of service with honor directed Godward, and it grounds divine remembrance in what has been manifested in action.

Hebrews 6:11: “We desire that each one of you may show the same diligence to the fullness of hope even to the end,”

“May show” introduces an exhortation aimed at perseverance. The object is “the same diligence,” and the scope is sustained (“even to the end”). Diligence is framed as something one can make evident, and it serves “the fullness of hope,” suggesting that hope’s maturity is accompanied by an observable steadiness of effort.

Sense and Usage

Across these passages, ἐνδείκνυμι consistently marks the transition from what could remain hidden to what becomes evident. In Romans 2:15 the movement runs from the heart to demonstrated moral awareness; the verse’s language of conscience and thoughts shows that “showing” can be the outward (or at least detectable) effect of inward realities. Romans 9:17 and 9:22 place the verb on God’s side: divine power, wrath, and patience are not merely asserted but made evident within history and in relation to particular persons and circumstances (“in you,” and through endurance). Ephesians 2:7 similarly presents God’s showing as an extended unveiling across time, where grace becomes visible in kindness.

In the letters addressing communities and conduct (2 Corinthians 8:24; Titus 2:10; Titus 3:2; Hebrews 6:11), the verb often functions imperatively or exhortatively. Love, fidelity, humility, and diligence are not left as internal virtues; they are to be rendered recognizable—“proof” that can be seen “before the assemblies,” an integrity that “adorn[s] the doctrine,” a humility practiced “toward all men,” a diligence sustained “to the end.” The practical shape of showing is especially explicit in Hebrews 6:10: service to “the saints” is the concrete form in which love has been shown and continues to be shown.

Two passages focus on persons as the location where something is shown. Romans 9:17 and 1 Timothy 1:16 both use “in me/you” language: God or Christ shows something in an individual, making that person’s situation a kind of display. In Romans the showing supports worldwide proclamation; in Timothy it provides “an example” for those who will believe. Together they illustrate how ἐνδείκνυμι can make a life or a historical moment into a public demonstration without changing the basic sense of “show.”

Imagery in Context

The verb’s imagery is frequently evidential: “proof” before witnesses (2 Corinthians 8:24), remembered labor expressed in service (Hebrews 6:10), and a steadiness that can be recognized over time (Hebrews 6:11). When God is the subject, the showing is portrayed as large in scope and effect—power that leads to proclamation (Romans 9:17), wrath and power made known amid patience (Romans 9:22), and grace exhibited in kindness across “the ages to come” (Ephesians 2:7). When believers are the subject, the showing is embodied in recognizable patterns of speech, restraint, and service (Titus 3:2; Titus 2:10; Hebrews 6:10), giving the word a strong connection to visible, testable conduct.
