HELPS Word-studies

1506 eilikrinḗs (from heilē, "shining of the sun" and 2929 /krystallízō, "to judge") – properly, rightly judged because seen in full light; (figuratively) judged in the rays of God's light, i.e. with divine clarity (spiritual vision) which results in real insight (discernment).

1506 /eilikrinḗs ("sincere because transparent") describes something proven because well-examined (totally scrutinized) – therefore, certified as sincere (inwardly pure). 1506 (eilikrinḗs) naturally refers to something completely clear, free from hypocrisy (deceit, wickedness) which stands in the full light of God's approval. This term is used twice in the NT (Phil 1:10; 2 Pet 3:1).

STRONGS NT 1506: εἰλικρινής

εἰλικρινής, ἐιλικρινες ((on the breathing see WH's Appendix, p. 144; Liddell and Scott, under the word, at the end); commonly supposed to be from εἴλη or ἕλη, sunlight, and κρίνω, properly, found pure when unfolded and examined by the sun's light; hence, some write εἰλικρινής. (see references above); according to the conjecture of others from ἐιλος, ἐίλειν, properly, sifted and cleansed by rapid movement or rolling to and fro), pure, unsullied, sincere; of the soul, an εἰλικρινής man: Philippians 1:10; διάνοια, 2 Peter 3:1. (Wis. 7:25, where cf. Grimm, Exgt. Hdb.; (see, on the word, also Trench, § lxxxv.); (Hippocrates), Xenophon, Plato (Aristotle, Plutarch), Polybius, Philo (others).) [SYNONYMS: εἰλικρινής, καθαρός: According to Trench as above the former word expresses freedom from the falsehoods, the latter from the defilements, of the flesh and of the world.]

Topical Lexicon
Overview

Strong’s Greek 1506 unfolds the idea of moral and spiritual transparency—an inner life free from admixture, shadow, or ulterior motive. The term pictures something examined in full light and found without hidden fault. Scripture applies it to the believer’s mind and character, calling for an integrity that can stand before God’s searching gaze.

Occurrences in the New Testament

1. Philippians 1:10 urges the church to “test and prove what is best, so that you may be pure and blameless for the day of Christ”. Here the word describes the believer’s inner quality as he or she anticipates final evaluation.
2. 2 Peter 3:1 records Peter’s desire “to stir you to a sincere mind”, a disposition fitted to recall prophetic warnings and apostolic commandments in view of coming judgment.

Though appearing only twice, the term anchors two key apostolic appeals: Paul’s prayer for holiness that withstands Christ’s tribunal, and Peter’s exhortation to clarity of mind that resists scoffers and holds fast to the promise of the Lord’s return.

Historical and Cultural Setting

Greco-Roman moralists esteemed candor and despised duplicity, yet public life was riddled with flattery, political intrigue, and religious syncretism. Against that backdrop, the word’s etymological image—something held up to sunlight to disclose flaws—would resonate with first-century readers. Christian proclamation radicalized the idea: the “sun-test” becomes God Himself, who “dwells in unapproachable light.” Genuine discipleship therefore demands a purity deeper than cultural ideals, grounded in regeneration and sustained by the Spirit.

Theological Significance

1. Eschatological Purity: Both texts connect sincerity with the day of divine reckoning. The Christian hope does not excuse moral laxity; it compels refinement of motives and actions.
2. Intellectual Integrity: Peter links the term to the mind, indicating that pure living begins with undiluted allegiance to revealed truth.
3. Covenant Faithfulness: Purity is not self-generated perfection but the fruit of union with Christ, whose own sincerity was vindicated in resurrection glory.

Ministry and Discipleship Implications

• Preaching and Teaching: Proclaim doctrine without mixture of human speculation, presenting the whole counsel of God.
• Pastoral Care: Cultivate transparency—confession, accountability, and unfeigned love—so congregations mirror Christ’s character.
• Leadership Qualification: Elders and deacons must exhibit this quality, guarding against hypocrisy that undermines witness.
• Evangelism and Apologetics: A life free of hidden agendas validates the gospel before a skeptical world.

Related Biblical Themes

Purity of heart (Psalm 24:4); integrity (Proverbs 10:9); singleness of eye (Matthew 6:22); guileless spirit (John 1:47); blamelessness (1 Thessalonians 5:23). Each motif converges on the same goal: undivided devotion that honors God and serves neighbor.

Contemporary Reflection

In an age of curated images and shifting loyalties, Strong’s 1506 challenges believers to submit thoughts, plans, and relationships to the searching light of Scripture. Such sincerity nourishes unity within the church, credibility before the world, and confident anticipation of the Lord’s appearing.
