But God hath revealed them unto us by his Spirit: for the Spirit searcheth all things, yea, the deep things of God. The adversative de (δέ, "but") pivots from human incapacity (v. 9) to divine disclosure. Apekalypsen (ἀπεκάλυψεν, "revealed") is aorist—definite historical action, likely referring to apostolic revelation recorded in Scripture. Dia tou pneumatos (διὰ τοῦ πνεύματος, "through the Spirit") identifies the Holy Spirit as revelation's agent, authenticating both Scripture's divine origin (2 Peter 1:21) and believers' illumination (John 16:13).
The explanation—the Spirit searcheth all things, yea, the deep things of God (to pneuma panta ereunaⁱ, kai ta bathē tou theou, τὸ πνεῦμα πάντα ἐραυνᾷ, καὶ τὰ βάθη τοῦ θεοῦ)—grounds revelation in Spirit's comprehensive knowledge. Ereunaō (ἐραυνάω) means "search thoroughly," not implying the Spirit lacks knowledge but that nothing escapes His complete understanding. Ta bathē (τὰ βάθη, "the depths") includes God's eternal decrees, redemptive purposes, and Trinitarian relationships. Only Spirit can reveal God because only Spirit fully knows God (v. 11).
Historical Context
Against Greek philosophy's confidence in human reason to discover truth, Paul insists revelation is necessary. The Stoics believed divine logos permeated cosmos, accessible through contemplation. Plato taught philosophers could ascend to knowledge of Forms. Paul rejects autonomous rationalism: God's "deep things" remain hidden unless God sovereignly discloses them. The Jewish concept of ruach Yahweh (Spirit of the LORD) inspiring prophets underlies Paul's pneumatology. Christian revelation is both external (Scripture) and internal (illumination).
