By full inclusion
Paul means
the full number of Jews who will be saved; or
when Israel will reign with Jesus at his second coming.
Paul explains that Israel’s trespass has brought riches to the Gentiles, how much more their full inclusion.
The question, then, is what Paul means by Israel’s full inclusion.
The most likely interpretation is that Paul refers to the full number of Israelites who will come to faith in Christ. This is supported by his use of the same term fullness in Romans 11:25, where a partial hardening has come upon Israel until the fullness of the Gentiles has come in.
There, fullness
most naturally denotes the full inclusion or total number of the Gentiles who will be saved. Given the proximity with Romans 11:12, Paul likely uses the same term in the same sense in Romans 11:12. That is, he has in mind their number being included.
The immediate context also supports this reading. Paul distinguishes between a present remnant in Israel (Romans 11:5) and those who are hardened (Romans 11:7). He then asks whether those who stumbled did so in order to fall permanently, and concludes No. Instead, their trespass has led to salvation for the Gentiles. In this light, their full inclusion
most naturally refers to the future inclusion of those presently hardened—that is, a much greater turning of Jews to Christ.
Some interpret their full inclusion
more broadly, as referring to Israel’s future reigning with Christ for a thousand years when Christ returns. The idea here is that the prophet Zechariah prophesies that Israel will eventually repent over the crucifixion. Then, Christ will return, and Israel will reign alongside him for a thousand years as he defeats Satan. Israel turning to Christ and reigning with him for a thousand years is their fulfillment (Revelation 20:1–10).
There are several problems with this interpretation. First, the notion that Israel will reign with Christ for a literal thousand years when Christ returns is not clearly indicated by Revelation 20:1–10. Revelation is apocalyptic literature, which often uses non-literal imagery to convey its teaching. Second, even if Revelation did teach that Christ will reign for one thousand years when he returns, there is nothing from Paul’s letter to the Romans that suggests Israel’s full inclusion
is their reigning with Christ during the millennium. Third, the immediate context strongly suggests that when Paul refers to their full inclusion,
he has in mind not Israel as a whole but those who were hardened turning to Christ.
Thus, when Paul says, If their trespass means riches for the world, how much more their full inclusion,
he most likely has in view the full inclusion of Israel in salvation, in contrast to the present partial hardening.
Interpretation 1:
Paul has in mind the full number of Jews who will be saved.
Summary:
Paul has explained that a remnant of Jews was kept by God, while the rest disobeyed by rejecting the gospel. He now teaches that if the Jews’ rejecting the gospel meant the Gentiles would be saved, how much more glorious will it be when those Israelites who formerly rejected the gospel are also saved.

Minor differences:
Our authors generally agree that when Paul refers to their full inclusion,
he has quantity in mind. That is, he has in mind the full number of Israelites who are destined for salvation.
James Dunn suggests that the term full inclusion
should be understood in the context of the remnant, and the rest who rejected the gospel. There is the small remnant whom God kept for himself, and the rest who disobeyed, and now Paul introduces the notion of all Israel being saved.1
Douglas Moo takes it that Paul has both quantity and quality in mind when he uses the term full inclusion.
On this reading, Paul is saying that when the number of Israelites saved is reversed from a small remnant to a greater number, then Israel will have reached her fullness. So qualitative fullness is reached by quantity.2

Interpretation 2:
Paul has in mind when Israel will reign with Jesus at his second coming.
Summary:
Some Old Testament prophets predicted that when Christ returns, Israel will reign with him for a thousand years during the time of the tribulation. At this time Satan will be defeated and salvation will go out to all the nations. When Paul refers to Israel being fulfilled, he has in mind this one-thousand-year reign with Christ.

12 Now if their trespass means riches for the world, and if their failure means riches for the Gentiles, how much more will their full inclusion mean!
