So I say, have they stumbled so as to fall [to spiritual ruin]? Certainly not! But by their transgression [their rejection of the Messiah] salvation has come to the Gentiles, to make Israel jealous [when they realize what they have forfeited].

and so [at that time] all Israel [that is, all Jews who have a personal faith in Jesus as Messiah] will be saved; just as it is written [in Scripture],

“The Deliverer (Messiah) will come from Zion,
He will remove ungodliness from Jacob.”

So then, each of us will give an account of himself to God.
