'Advantage' in the Bible

Then what is the advantage of the Jew? Or what is the benefit of circumcision?

Now if Israel’s transgression means riches for the world [at large] and their failure means riches for the Gentiles, how much more will their fulfillment and reinstatement be!

From the standpoint of the gospel, the Jews [at present] are enemies [of God] for your sake [which is for your benefit], but from the standpoint of God’s choice [of the Jews as His people], they are still loved by Him for the sake of the fathers.
