The inheritance (hē klēronomia). Old word from klēronomos, heir (kleros, lot, nemomai, to distribute). See Mat 21:38; Act 7:5. This came to Israel by the promise to Abraham, not by the Mosaic law. So with us, Paul argues.
Hath granted (kecharistai). Perfect middle indicative of charizomai. It still holds good after the law came.
