Romans 11:31
So, now these [same] Jews have also been disobedient [to God], so that they may also now obtain [God's] mercy by means of the mercy [He has] shown to you [Gentiles].
Romans 10:16
But not everyone [of the Israelites] obeyed [that] good news. For Isaiah said [Isa. 53:1], "Lord, who has believed our message?"
Romans 11:15
For if their rejection [by God] meant that [the rest of] the world could be restored to favor [with God], what would [God's] receiving the Jews back into fellowship be, except like dead people coming back to life?
Romans 11:25
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].
