Shared ground
Paul’s “confidence” is presented as real but not self-made. It is through Christ and aimed toward God (v.4). He then blocks a misunderstanding: neither he nor his coworkers are “sufficient” in themselves to credit any meaningful ministry outcome to their own resources (v.5). Any adequacy comes from God.
Paul also ties that God-given adequacy to a particular calling: God has made them “servants of a new covenant” (v.6). The newness is marked by a contrast: not of “letter” (letter) but of “spirit”. Paul summarizes the stakes with a sharp line: “the letter kills, but the spirit gives life.”
Where interpretation differs
Some disagreement centers on what “letter” and “spirit” mean in v.6.
- One reading takes “letter” mainly as God’s written law and its commandments when treated as an external code. On this view, “kills” points to how the law exposes and condemns sin, while “spirit” refers to God’s Spirit giving new life under the new covenant.
- Another reading takes “letter” more broadly as any merely external, document-based, or rule-focused way of relating to God (including how someone might use Scripture itself), while “spirit” points to the inward, Spirit-empowered reality the new covenant produces. On this view, the contrast is less about a specific set of commands and more about a whole mode of ministry and transformation.
There is also a smaller question about what Paul means by “account anything as from ourselves” (v.5): whether he means outcomes of ministry, the right to claim credit, or even the ability to make proper judgments in ministry. The text clearly denies self-sufficiency, but it does not itemize every category.
Why the disagreement exists
Paul uses compact, contrastive language without defining his terms here (“letter,” “spirit,” “kills,” “gives life”). The surrounding context (3:1–3 and what follows in chapter 3) suggests he is setting up a larger comparison of covenant ministries, but vv.4–6 alone leave more than one plausible scope for “letter” and for what “kills” refers to.
What this passage clearly contributes
- It explicitly grounds Paul’s ministerial confidence in God’s action mediated “through Christ” (v.4), not in personal capability (v.5).
- It explicitly describes God as the source of ministerial adequacy and commissioning (vv.5–6).
- It explicitly frames Paul’s ministry as “new covenant” service marked by “spirit,” and it states a life-and-death contrast between “letter” and “spirit” (v.6). This makes divine enabling central to how Paul understands legitimate ministry and its effects.
