Shared ground
Paul treats generous giving as something God produces in communities. He calls it “the of God” at work in the Macedonian churches (explicit). Their circumstances were hard—“severe affliction” and “deep poverty”—yet their joy “overflowed” into practical generosity (explicit). Paul also presents giving as voluntary: they gave “of their own accord” and even pleaded to be included in the shared service for “the saints” (explicit).
Paul then explains the inner source of that generosity: they “first gave themselves to the Lord,” and then aligned themselves with Paul’s team “through the will of God” (explicit). The result is a model Paul uses to move the Corinthian project forward: Titus is urged to help them “complete” the same “grace” (explicit), and Corinth’s strengths in faith, speech, knowledge, and eagerness are meant to be matched by excelling in this generous act (explicit).
Where interpretation differs
What “grace” means here. Some read “grace” mainly as God’s empowering work that produces generosity in believers (inference from vv.1–2, 6–7). Others read it more concretely as the gift/collection itself—“this grace” meaning the specific relief offering (inference from vv.4, 6–7). Many interpreters see both senses at once: God’s enabling expressed through a tangible gift (inference).
Who “the saints” are. Some think “the saints” refers to a specific needy group known to the churches (often understood as a particular community of believers in distress), because Paul speaks of an organized, multi-church “service” (inference from vv.4, 6). Others take it more generally as believers in need wherever they are (inference), though this section itself does not name the location (explicitly unspecified).
What “beyond their power” implies. Some read it as extraordinary sacrifice that still remains wise and truly voluntary—Paul’s emphasis is eager participation, not coercion (inference from vv.3–4). Others think it suggests a kind of self-emptying risk that could look imprudent from the outside, and Paul is highlighting how surprising their choice was (inference from v.3). The text itself stresses willingness and eagerness rather than evaluating budgeting practices (explicit focus).
Why the disagreement exists
Paul uses compact phrases that can point in more than one direction. “Grace” can mean God’s favor and enabling, and it can also name a specific generous act or gift; in this paragraph Paul appears to move between God’s action (vv.1–2) and the collection as a shared project to be completed (vv.6–7). Likewise, “the saints” is a defined group in Paul’s mind, but the passage does not specify where they are, leaving readers to connect it with other parts of 2 Corinthians and Paul’s wider ministry.
What this passage clearly contributes
This paragraph links outward generosity to inward allegiance: the Macedonians’ giving is rooted in giving themselves “first…to the Lord” (v.5). It frames financial assistance as a shared ministry—“fellowship in the service”—rather than mere charity (v.4). It also shows Paul’s method: he reports God’s work in one set of churches to motivate completion in another, and he uses a trusted coworker (Titus) to help bring the project to completion (vv.6–7).
