Paul pleads with the Corinthians not to receive God's grace in vain. He defends his ministry by listing the hardships he has endured, then urges believers to open their hearts to him. The chapter concludes with a powerful call to separate from unbelievers and pursue holiness, grounding this appeal in Old Testament promises of God's presence among His people.
Paul structures these verses as a bridge from the theological exposition of reconciliation (5:11-21) to the practical implications for the Corinthian community. The participial phrase 'working together' (synergountes) is grammatically ambiguous—it could be construed absolutely ('as co-workers') or with an implied object ('working together with Him'). The LSB's 'working together with Him' captures the most natural reading given the context of 5:20, where Paul has just described himself as Christ's ambassador. The present participle indicates that Paul's exhortation flows directly from his ongoing collaborative ministry with God in the reconciliation project.
The negative purpose clause 'not to receive the grace of God in vain' (mē eis kenon tēn charin tou theou dexasthai) employs the aorist infinitive to denote a completed action with potential null result. Paul is not warning against failing to receive grace initially, but against receiving it without allowing it to accomplish its intended transformative purpose. The prepositional phrase eis kenon ('into emptiness') suggests grace poured out but producing no fruit, like water spilled on impervious ground. This sets up the urgent temporal appeal that follows.
Verse 2 introduces an Old Testament quotation (Isaiah 49:8) with the simple 'he says' (legei), using the historical present to make the ancient word contemporaneous. Paul then pivots dramatically with the double 'behold, now' (idou nyn... idou nyn), transforming Isaiah's prophetic promise into present reality. The shift from past tense verbs in the quotation ('I listened,' 'I helped') to the present substantives ('now is the acceptable time, now is the day of salvation') creates rhetorical urgency. The article with 'acceptable time' and 'day of salvation' points back to the Isaiah quotation, declaring its eschatological fulfillment in the gospel age. The emphatic repetition and present-tense construction leave no room for delay—the prophesied moment has arrived.
Grace received but not lived is grace rejected. The gospel creates not merely a new standing but a new season—and that season is now, demanding immediate, wholehearted response.
Paul quotes directly from Isaiah 49:8, a passage within the second Servant Song where Yahweh addresses His Servant and promises to answer Him 'in a time of favor' and help Him 'in a day of salvation.' In its original context, this oracle assures the Servant (and through Him, Israel) that God will respond at the appointed time, restoring the nation and making the Servant 'a covenant for the people, a light for the nations.' The temporal markers—'acceptable time' and 'day of salvation'—point to a specific moment in God's redemptive calendar when He will act decisively to rescue and restore.
Paul's hermeneutical move is breathtaking: he takes Isaiah's prophetic promise and declares it fulfilled in the present gospel age. The 'now' (nyn) appears twice for emphasis, transforming future promise into present reality. What Isaiah anticipated, Paul announces as arrived. The Servant has come, the covenant has been established, and the day of salvation is no longer future but present. This interpretive strategy reflects Paul's conviction that Christ's death and resurrection have inaugurated the eschatological age, collapsing the 'not yet' into the 'already.' The Corinthians stand within the very time Isaiah foresaw, making their response to grace a matter of urgent, immediate consequence.
Paul constructs verses 3-10 as a single, breathtaking sentence in Greek—a rhetorical torrent that overwhelms by accumulation. The structure pivots on two participles: διδόντες ('giving,' v. 3) negatively frames what Paul avoids, while συνιστάνοντες ('commending,' v. 4) positively introduces what follows. The latter governs an avalanche of twenty-eight prepositional phrases (ἐν + dative), creating a rhythmic, almost liturgical catalog. The first nine items (vv. 4b-5) detail external hardships; the next nine (vv. 6-7a) enumerate internal virtues and divine resources; the final section (vv. 7b-10) shifts to διά constructions and ὡς clauses, presenting the paradoxes of apostolic existence. This triadic structure—suffering endured, character displayed, paradox embodied—maps the comprehensive validation of Paul's ministry.
The repeated preposition ἐν functions as the grammatical engine of verses 4-7a, but its semantic force shifts subtly across the catalog. In the hardship list (vv. 4b-5), ἐν denotes circumstance: 'in the midst of afflictions.' In the virtue list (vv. 6-7a), ἐν indicates manner or means: 'by means of purity, knowledge, patience.' This grammatical fluidity allows Paul to present suffering and virtue not as separate categories but as interpenetrating realities—the apostle displays godly character precisely within crushing circumstances. The shift to διά ('through,' v. 7b-8a) introduces instrumentality: Paul ministers 'through' both honor and dishonor, wielding even opposition as a tool. Finally, the ὡς ('as,' vv. 8b-10) clauses present appearance versus reality, the world's verdict versus God's truth.
The paradoxes of verses 8b-10 employ a consistent grammatical pattern: ὡς + participle/adjective + καί/δέ + contrasting participle/adjective. This creates a staccato rhythm of thesis and antithesis: 'as deceivers and yet true, as unknown yet well-known.' The participles are predominantly present tense, emphasizing ongoing, simultaneous realities—Paul is not describing sequential states but coexisting truths. The climactic triad of verse 10 intensifies with each clause: 'as sorrowful yet always rejoicing' (emotional paradox), 'as poor yet making many rich' (economic paradox), 'as having nothing yet possessing all things' (ontological paradox). The final phrase πάντα κατέχοντες employs the intensive compound verb to assert comprehensive ownership, the ultimate reversal of apparent destitution. This is not mere rhetoric but theological claim: in Christ, the cruciform pattern of death-yielding-life becomes the apostle's daily existence.
The apostle's credentials are his scars, his wealth is his poverty, his life is his dying—Paul dismantles every human metric of ministerial success and replaces it with the paradox of the cross. True ministry is validated not by avoiding suffering but by enduring it with integrity, not by accumulating resources but by dispensing them, not by self-promotion but by self-giving that mirrors the kenosis of Christ himself.
Paul shifts from third-person description of his ministry (vv. 3-10) to direct, impassioned address. The vocative 'O Corinthians' (Κορίνθιοι) is rare in Paul's letters—he uses it only here and in 2 Cor 6:11 and Gal 3:1, always at moments of intense emotional appeal. The perfect tenses in verse 11 (ἀνέῳγεν, πεπλάτυνται) emphasize the settled, ongoing state of Paul's openness: his mouth remains open, his heart continues enlarged. This is not a momentary gesture but an abiding posture of vulnerability and affection toward a congregation that has caused him profound pain.
Verse 12 employs a striking antithesis through repeated vocabulary with contrasting subjects. 'You are not restrained (στενοχωρεῖσθε) in us, but you are restrained (στενοχωρεῖσθε) in your own affections (σπλάγχνοις).' The spatial metaphor is vivid: Paul's heart is a wide-open space (πεπλάτυνται), offering ample room for the Corinthians, but their own emotional capacity (σπλάγχνοις) has become narrow and constricted (στενοχωρεῖσθε). The problem is not external—Paul has not closed himself off—but internal. They are hemmed in by their own suspicions, resentments, or divided loyalties. The present tense verbs underscore the ongoing nature of this self-imposed restriction.
Verse 13 issues the appeal with carefully calibrated rhetoric. The phrase 'in a like exchange' (τὴν δὲ αὐτὴν ἀντιμισθίαν) frames the request as reciprocity, not demand—Paul seeks correspondence, a matching response to his own openness. The parenthetical 'I speak as to children' (ὡς τέκνοις λέγω) is simultaneously tender and authoritative. It softens the imperative that follows while also reminding them of their obligation: children owe their parents responsive affection. The aorist imperative 'open wide' (πλατύνθητε) echoes the perfect 'has been opened wide' (πεπλάτυνται) from verse 11, creating a verbal mirror. Paul has modeled the posture he now commands. The emphatic 'you also' (καὶ ὑμεῖς) at the end underscores the reciprocal nature of the appeal—he has done his part; now they must do theirs.
Relational distance is rarely imposed from without; it is cultivated from within. Paul's plea exposes the Corinthians' self-constriction—they are cramped not by his coldness but by their own narrow affections—and invites them into the spacious vulnerability he has already extended.
Paul structures this passage as a sustained rhetorical crescendo, building from prohibition to promise through a carefully orchestrated series of five rhetorical questions (vv. 14b-16a), a theological declaration (v. 16b), and a composite Old Testament quotation (vv. 16c-18). The opening imperative, 'Do not be bound together' (μὴ γίνεσθε ἑτεροζυγοῦντες), uses the present tense with μή to command the cessation of an ongoing action—the Corinthians are apparently already entangled in relationships Paul deems spiritually compromising. The agricultural metaphor of unequal yoking provides the controlling image, but Paul immediately shifts to abstract relational terms (partnership, fellowship, harmony, common ground, agreement) to explore every conceivable angle of the incompatibility between belief and unbelief.
The five rhetorical questions escalate in intensity and specificity. The first pair (v. 14b) contrasts abstract moral categories: righteousness versus lawlessness, light versus darkness. The second pair (v. 15) personalizes the conflict: Christ versus Beliar, believer versus unbeliever. The fifth question (v. 16a) brings the issue to its theological climax: what agreement can God's sanctuary have with idols? Each question expects the answer 'None!'—a fact so obvious that Paul doesn't bother to state it. The anaphoric repetition of τίς ('what') and the varied vocabulary for relationship create a hammering effect, closing off every possible avenue of compromise. The structure itself enacts Paul's argument: there is no common ground, no middle way, no synthesis possible.
Verse 16b pivots from interrogation to declaration with γάρ ('for'), grounding the ethical imperative in theological reality: 'we are the sanctuary of the living God.' This is not aspiration but fact, and Paul immediately supports it with a catena of Old Testament texts woven together (drawing from Leviticus 26:11-12, Ezekiel 37:27, Isaiah 52:11, 2 Samuel 7:14, and possibly others). The quotations are introduced with standard formulae ('just as God said,' 'says the Lord,' 'says the Lord Almighty'), lending divine authority to the call for separation. The logic is covenantal: because God dwells among his people (v. 16c), therefore they must separate from defilement (v. 17), so that the Father-child relationship may be fully realized (v. 18). The future tenses in the promises ('I will welcome you,' 'I will be a father to you') are not conditional but consequential—they describe what will inevitably follow from obedient separation.
The passage's grammar of separation is matched by a grammar of belonging. The pronouns shift tellingly: 'their midst' (ἐκ μέσου αὐτῶν) marks the place believers must leave, while 'my people' (μου λαός), 'to you' (ὑμῖν), and 'to me' (μοι) establish the intimate reciprocity of covenant relationship. The divine 'I will' statements (ἐνοικήσω, ἐμπεριπατήσω, ἔσομαι, εἰσδέξομαι) pile up as promises, each verb depicting God's active commitment to his separated people. The final title, 'Lord Almighty' (κύριος παντοκράτωρ), functions as the divine signature on these covenant promises, assuring the Corinthians that the one who calls them to costly separation is the one who possesses all power to fulfill what he promises.
Separation from the world is not isolation but consecration—not the absence of relationship but the presence of a greater one. Paul's call is not fundamentally negative but covenantal: we separate from what is incompatible with God's indwelling precisely because we are the sanctuary where the living God has chosen to dwell.
The LSB's rendering of ἑτεροζυγοῦντες as 'bound together' captures the yoking metaphor while remaining accessible to modern readers. Some translations opt for 'unequally yoked' (following the KJV tradition), which preserves the agricultural imagery more explicitly but risks sounding archaic. The LSB's choice maintains the sense of binding or partnership without requiring readers to understand ancient farming practices, though it does sacrifice some of the vividness of the original metaphor.
In verse 16, the LSB translates ναός as 'sanctuary' rather than the more common 'temple.' This is a significant choice that highlights the distinction between ναός (the inner holy place) and ἱερόν (the temple complex as a whole). By using 'sanctuary,' the LSB emphasizes the sacred, set-apart nature of believers as the dwelling place of God's presence. This translation choice underscores the gravity of Paul's argument: believers are not merely associated with God's temple; they are the very sanctuary where his presence resides, the holy of holies made living and corporate.
The LSB preserves the direct quotation formula 'says the Lord' (λέγει κύριος) in verses 17 and 18, maintaining the prophetic tone of Paul's composite Old Testament citation. Some modern translations smooth this into indirect discourse or eliminate the repetition, but the LSB's retention of the formula emphasizes the divine authority behind the commands and promises. The final title 'Lord Almighty' (κύριος παντοκράτωρ) is rendered with appropriate majesty, capturing the Septuagintal echo of 'LORD of hosts' and the sovereign power implied in the Greek term.
