c. τινα, to fill one with any thought, conviction, or inclination: (Romans 15:13 L marginal reading (followed by ἐν with the dative of thing): others, πληρόω, which see, 1); hence, to make one certain, to persuade, convince, one (πολλαῖς οὖν λόγοις καί ὅρκοις πληροθορησαντες Μεγαβυζον, extracted from Ctesias () in Photius, p. 41, 29 ((edited by Bekker); but on this passive, see Lightfoot as below)); passive, to be persuaded, Romans 14:5; πληροθορηθεις, persuaded, fully convinced or assured, Romans 4:21; also πεπληροθορήμενοι, Colossians 4:12 L T Tr WH; οἱ ἀπόστολοι ... πληροθορηθεντες διά τῆς ἀναστάσεως τοῦ κυρίου Ἰησοῦ Χριστοῦ καί πιστωθενθες ἐν τῷ λόγῳ τοῦ Θεοῦ, Clement of Rome, 1 Cor. 42, 3 [ET]; frequent so in ecclesiastical writings; to render inclined or bent on, ἐπληροθορηθη καρδία ... τοῦ ποιῆσαι τό πονηρόν, Ecclesiastes 8:11 (cf.

Scope of the Term

Strong’s 4135 describes a movement from potential to completion. Whether applied to events, persons, or ministries, it conveys the idea of bringing something to full measure so that nothing lacking remains—hence “fully convinced,” “fully accomplished,” or “fulfilled.” The verb highlights God’s faithfulness to finish what He begins and the believer’s responsibility to see a God-given task through to the end.

Occurrences and Contextual Emphases

Luke 1:1 – Luke introduces his Gospel with the affirmation that the redemptive events concerning Jesus have already been “fulfilled among us.” The perfect participle underscores historical certainty: the deeds of Jesus are not mere hopes but accomplished realities. Luke roots the narrative in completion so that Theophilus may possess unshakable confidence (Luke 1:4).

Romans 4:21 – Abraham was “fully convinced that God was able to do what He had promised.” Full assurance rests on God’s omnipotence, not human probability. Paul cites Abraham as the prototype of saving faith: justification depends on trusting the God who completes His word.

Romans 14:5 – In disputable matters each believer “should be fully convinced in his own mind.” The verse guards liberty of conscience while maintaining unity. Personal persuasion must be informed by Scripture and charity, never by self-will.

Colossians 4:12 – Epaphras prays that the Colossians “may stand mature and fully assured in all the will of God.” Spiritual maturity is marked by settled certainty about God’s purposes, not by mystical uncertainty. Prayer is portrayed as the means through which such assurance is forged.

2 Timothy 4:5 – Timothy is commanded, “fulfill your ministry.” The verb turns a pastoral charge into a finishing assignment. Ministry is not complete when begun; it must be carried through every season, including hardship.

2 Timothy 4:17 – Paul testifies, “through me the proclamation might be fully accomplished and all the Gentiles might hear it.” Even in Roman custody the gospel mission advances to completion, demonstrating Christ’s abiding presence and sovereign oversight.

Theological Threads

1. Fulfillment of Salvation History

Luke 1:1 links the verb to covenant completion. God’s historical acts in Christ stand as irreversible milestones; they warrant the believer’s confidence that final redemption will likewise be brought to fullness (Philippians 1:6).

2. Assurance of Faith

Romans 4:21 and Colossians 4:12 pair the verb with faith’s interior certainty. Assurance is not presumption but a Spirit-bred conviction anchored in divine promise (Hebrews 10:22).

3. Completion of Calling

2 Timothy 4:5-17 applies the term to ministry. Servants of Christ are summoned to persevere until their assigned work is finished, mirroring Jesus’ own declaration, “It is finished” (John 19:30).

4. Conscience and Liberty

Romans 14:5 shows that full persuasion is essential for ethical integrity. The mature conscience operates with clarity, informed by Scripture and love, resisting both legalism and libertinism.

Historical and Pastoral Significance

Early Christian writers saw in Luke 1:1 a methodological model: careful research wedded to doctrinal conviction. Reformation expositors frequently cited Romans 4:21 to affirm the doctrine of sola fide, insisting that faith relies on a promise already secured in Christ. Puritan pastors drew on 2 Timothy 4:5 to exhort diligence in preaching and pastoral care, stressing that unfinished ministry is disobedience to mandate.

Practical Applications

• Cultivate assurance by meditating on fulfilled prophecy and accomplished redemption.
• Intercede for fellow believers that they may stand “fully assured” amid cultural turbulence.
• Evaluate personal calling: What remains unfinished? Resolve, like Timothy, to “fulfill your ministry.”
• Exercise Christian liberty responsibly, ensuring that every decision arises from a mind “fully convinced” and seeks the edification of others.

Summary

Strong’s 4135 traces a thread of divine completion through Scripture: God fulfills His saving acts, convinces His people of their security in Christ, and calls them to carry out their unique tasks to the end. When that fullness characterizes events, faith, conscience, and service, the church reflects the perfect faithfulness of her Lord.
