1 Thessalonians 3

Verses 1-2 resume the problem of separation described in 2:17-20. The repeated language of no longer being able to "bear" the uncertainty explains the decision to remain alone at Athens while Timothy was sent to Thessalonica. Timothy is called "our brother" and, according to the dominant critical text, "God's coworker in the gospel of Christ." The wording of this description varies considerably across manuscripts, with alternatives such as "servant of God" and combinations of "servant" and "coworker," probably reflecting scribal discomfort with or clarification of the striking expression "God's coworker." Timothy's purpose is expressed through complementary infinitives: to establish and encourage the believers concerning their faith.

Verses 3-4 interpret the congregation's afflictions within Paul's prior teaching. The verb sainesthai in verse 3 is unusual and may mean "be disturbed," "be shaken," or possibly "be beguiled" by sufferings. Paul states that believers are "appointed" for such afflictions and reminds the Thessalonians that he had repeatedly predicted persecution. The language does not identify suffering as intrinsically desirable; rather, it places opposition within the expected circumstances of the mission, consistent with what Acts reports about Thessalonica.

Verse 5 restates Paul's concern in explicitly apocalyptic terms. "The tempter" is a designation for Satan, whose activity Paul had already invoked in 2:18. The aorist indicative epeirasen, "tempted," occurs within a clause expressing Paul's fear that temptation might have undermined the community and made the missionaries' kopos, "labor," empty or ineffective. The anxiety is therefore not merely personal separation but the possibility that persecution could reverse the Thessalonians' response to the gospel.

First Thessalonians 3 completes the autobiographical section begun in 2:17 by explaining how Paul responded to his forced separation from the Thessalonian believers. Verses 1-5 describe the decision to send Timothy from Athens to strengthen and encourage the congregation amid persecution. Paul presents suffering not as an unexpected failure of the mission but as something already anticipated within the Christian vocation. His anxiety centers on whether the tempter might exploit affliction and render the missionaries' labor ineffective.

Verses 6-13 turn from anxiety to relief after Timothy returns with favorable news about the Thessalonians' faith, love, and continuing attachment to Paul. Their steadfastness becomes a source of consolation to the missionaries in their own distress. The chapter culminates in prayer: Paul asks God to enable a return visit, increase the Thessalonians' love, and establish their hearts in holiness at the coming of Jesus. This prayer provides a transition from the letter's retrospective narrative to the ethical and eschatological instruction of chapters 4-5.
