But it is not as if the word of God [i.e., His promise to Israel] has failed [in its fulfillment]. For not all those descended from the Israelites are [truly] Israelites [i.e., God's people].

But the [means of] being made right with God by faith [in Christ] is described in the Scripture this way [Deut. 30:12-13], "Do not ask yourself, 'Who will go up into heaven?'" (in order to bring Christ down [to earth]).

"And [do not ask yourself], 'Who will go down into the deep hole?'" (in order to bring Christ up from the dead). [Note: This "deep hole" probably refers to the unseen place of departed spirits, or possibly the grave. Being made right with God does not require something as difficult as bringing Christ down from heaven or up from the dead (which God had already done), but is within easy reach of everyone].

For I want you to know this secret, brothers, so you will not become conceited: Part of the Israelites have become [spiritually] insensitive [to God], [and will remain that way] until the fullness of the Gentiles occurs. [Note: As with verse 12, concerning the Jews, "fullness" here may mean either a large or the complete number of Gentiles who will be saved].
