He opens by challenging a rival reading. To make the case, he turns first to the Psalms, where phrases like 'in God' and 'in thee' are treated as idioms for help from God rather than as statements about acting inside the divine essence. He then brings in Paul, arguing that thanksgiving for grace given in Christ, and the claim that believers are 'of him' in Christ Jesus, cannot be forced into a theory that makes every phrase refer to essence itself; that reading simply does not hold. He returns to 'in him we live, and move, and have our being' and insists that it means dependence on God, not location inside the Father's substance. The chapter closes by arguing that the Son's works reveal the Father's power so clearly that their matching deeds point away from separation of essence and toward a unity of nature.
