Why does Paul express a desire to "supply what is lacking" in their faith? Immediate Context in 1 Thessalonians Paul had been forced out of Thessalonica after only a matter of weeks (Acts 17:1-10). Concerned about the infant church, he dispatched Timothy, “to strengthen and encourage you concerning your faith” (1 Thessalonians 3:2). Timothy’s positive report (3:6-8) relieved Paul, yet the apostle still longed to visit personally, because written words and emissaries could not replace direct apostolic teaching, modeling, and correction (cf. 2 Thessalonians 2:5). Historical and Cultural Background Thessalonica was a free city in Macedonia, strategically located on the Via Egnatia. Archaeological discoveries confirm Luke’s accuracy in calling its magistrates “politarchs” (Acts 17:6)—a title found on first-century local inscriptions now housed in the British Museum. Such data underscore the historical reliability of Acts and, by extension, Paul’s movements described there. The Greek Term “katartisai” – Fill Up, Equip, Perfect In classical and Koine usage, katartizo depicts bringing something to its intended state. In Galatians 6:1 it refers to “restoring” a brother; in Hebrews 13:21 God “equip[s]” believers for every good work. Paul envisions a faith that is authentic yet in need of maturation—bones set but not yet fully rehabilitated, nets tied yet not entirely fit for the next catch. Nature of the Thessalonian Believers’ Faith 1 Th 1:3 commends their “work of faith,” demonstrating authenticity. However, being former pagans (1 Thessalonians 1:9-10) they lacked grounding in Scripture, ecclesiology, and eschatology. Their anxieties about deceased believers (4:13), sexual ethics (4:3-8), and spiritual gifts (5:19-22) illustrate specific gaps. Areas Paul Sought to Complete: Doctrinal, Moral, Eschatological 1. Doctrine of the Resurrection and Second Coming (4:13-18; 5:1-11). 2. Sanctification in daily conduct (4:1-8). 3. Brotherly love and disciplined labor (4:9-12). 4. Church order—respect for leaders, discernment of prophecies, persistence in prayer (5:12-22). Pastoral Motive and Apostolic Authority Paul calls himself a nursing mother and exhorting father (2:7-11). Apostolic presence carried unique revelatory and disciplinary authority (cf. 1 Corinthians 4:21). His desire is not to control but to nurture; the metaphor is constructive, not punitive. Spiritual Formation: Justification and Ongoing Sanctification Justification is instantaneous (Romans 5:1), yet sanctification is progressive (1 Thessalonians 4:3). Paul prays that God would “sanctify you completely” (5:23) while simultaneously planning to teach and model obedience. Divine action and human instruction cooperate without contradiction. Divine Sovereignty and Human Instrumentality Paul prays “may our God…direct our way to you” (3:11) acknowledging God’s providence, yet he still strategizes travel and writes letters, embodying the biblically balanced view that God ordains both ends and means (cf. Philippians 2:12-13). Patterns in Pauline Correspondence Similar language appears in 2 Corinthians 13:9 (“your restoration”) and Colossians 1:28 (“present everyone perfect”). The apostle’s consistent aim is believers’ maturity, not merely conversion. Application for the Church Today Christian leaders must identify and address doctrinal and ethical deficiencies—even in vibrant congregations. Personal presence, not merely digital communication, remains vital for discipleship. Prayer for opportunities should precede planning. Illustrative Parallels from Later Church History During the Great Awakening, George Whitefield often returned to nascent fellowships to “form Christ in them,” echoing Paul’s practice. Modern missionaries likewise establish Bible institutes after initial evangelism, recognizing that faith needs scaffolding. Conclusion Paul’s yearning to “supply what is lacking” reflects an apostolic conviction that saving faith is the starting point of an ever-deepening relationship with Christ. Through prayerful dependence on God and intentional teaching, the unfinished is brought to completion until “He who calls you is faithful, and He will do it” (1 Thessalonians 5:24). |
