STRONGS NT 1650: ἔλεγχος

ἔλεγχος, ἐλέγχου, (ἐλέγχω);

1. a proof, that by which a thing is proved or tested (τό πρᾶγμα τόν ἔλεγχον δώσει, Demosthenes 44, 15 (i. e. in Philippians 1:15); τῆς εὐψυχίας, Euripides, Herc. fur. 162; ἐνθαδ' ἔλεγχος τοῦ πράγματος, Epictetus diss. 3, 10, 11; others): τῶν (or rather, πραγμάτων) οὐ βλεπομένων, that by which invisible things are proved (and we are convinced of their reality), Hebrews 11:1 (Vulg.argumentumnonapparentium (Tdf.rerumarg.nonparentum)); (others take the word here (in accordance with the preceding ὑπόστασις, which see) of the inward result of proving viz. a conviction; see Lünem, at the passage).

2. conviction (Augustine,convictio): πρός ἔλεγχον, for convicting one of his sinfulness, 2 Timothy 3:16 R G. (Euripides, Plato, Demosthenes, others; the Sept. chiefly for תּוכַחַת.)

Topical Lexicon
Meaning and Scope of the Term

The word denotes a demonstrative proof that exposes error and brings something to the light so that its true character is unmistakable. It functions both negatively (showing a fault) and positively (establishing what is real and sure).

Occurrences in the New Testament

1. 2 Timothy 3:16 – Paul lists Scripture as “useful for instruction, for conviction, for correction, and for training in righteousness”. Here the term highlights Scripture’s capacity to confront false belief or behavior and establish what is right.
2. Hebrews 11:1 – “Now faith is the assurance of what we hope for and the certainty of what we do not see”. Faith receives unseen realities as proven facts. The term underscores that biblical faith rests on firm evidence supplied by God Himself, not on wishful thinking.

Theological Significance

Conviction or proof is central to God’s revelation. By it:
• Scripture exposes sin (Psalm 19:7-11; James 1:22-25) and secures doctrinal soundness (Titus 1:9).
• The Spirit brings sinners to repentance (John 16:8-11), using the Word as His instrument.
• Believers gain confidence in unseen promises (Romans 4:20-21; 1 Peter 1:8-9).

Historical and Pastoral Context

Early Christian teachers cherished the term because it protected the church from error. The Pastoral Epistles repeatedly command leaders to “rebuke” (a cognate verb) those who contradict sound teaching (2 Timothy 4:2; Titus 1:13). Hebrews, written to wavering Jewish believers, employs the noun to insist that faith itself is grounded on objective, God-given proof.

Relationship to Allied Biblical Concepts

• Discipline: Hebrews 12:5-11 connects reproof with fatherly training.
• Testimony: The term overlaps with “witness” (martyria) in affirming verified truth (John 5:31-39).
• Assurance: Believers’ subjective confidence (1 John 5:13-15) rests on objective conviction granted by God’s Word and Spirit.

Application in Preaching and Teaching

• Expository preaching should allow the text to do its convicting work rather than relying on human persuasion.
• Counseling must present Scriptural proof that exposes sinful patterns while offering the substantiated hope of the Gospel.
• Evangelism should appeal to the Spirit-wrought certainty that the resurrection of Jesus is “proof to all men” (Acts 17:31).

Practical Ministry Implications

1. Saturate ministry with Scripture so that conviction is God-centered, not personality-driven.
2. Combine conviction with correction and training, following the balanced pattern of 2 Timothy 3:16.
3. Encourage believers that faith is anchored in reality already attested by God; doubt is addressed not by suppressing questions but by returning to the evidence God supplies.

Summary

Strong’s 1650 points to the God-given proof that unmasks error and establishes truth. Through Scripture and the witness of the Spirit, it brings sinners to repentance, strengthens the faith of believers, and safeguards the church’s purity until Christ returns.
