Romans 11:12

Now if their fall, is the riches of the world, and their loss the riches of the Gentiles; how much more their fulness? "their fall" -what happened when Jewish people rejected the gospel.

"riches of the world..riches of the Gentiles" -Gentiles benefited from Jewish rejection, in the sense that such rejection enabled the messengers of the gospel to spend more time preaching to Gentiles. (Acts 13:46; Acts 18:6; Acts 19:9)

"how much more their fulness" -'what an enrichment will follow their reinstatement! (Wey)

Points to Note:

A. 'Their fulness', is not speaking of some future conversion of every Jewish person on the face of the planet.

B. 'Fulness' in verse 12, is placed in contrast with 'fall, loss', neither one of these words suggest any idea of 'number'. 'Their fulness', is the exact opposite of 'their fall'. And since every Jew didn't fall by unbelief and miss the blessings of salvation, the end of the verse cannot mean that every Jew (at some later time) will come to faith. Rather Paul is saying, 'If Gentiles benefited from Israel's rejection of the gospel, if others benefited from their misfortune, how much more will it be. wonderful thing, if some of these unbelieving Jews turn to God!' If unbelieving Jews would simply turn to Christ, they would be fully blessed!
