Will every living Jew be part of the saved remnant when God restores Israel?
No, not every living Jew will be included; Scripture indicates only a saved remnant will be brought into the nation. However, once that remnant is gathered, not one will be lost, just as not a single fish escaped the net.
Les explains that the saved of Israel will only be a remnant, and it is not going to be every Jew that is living. But when God brings that remnant into the nation of Israel, not a one is going to be lost. He compares this to the net full of fishes where not a one flopped out, which is why the count was given as 153. Les also points to Amos 9:9, where God says He will sift the house of Israel among all nations like corn sifted in a sieve, yet not the least grain will fall upon the earth. So not a kernel of what God wants to keep will be lost. Thus, while not all living Jews are part of the remnant, the remnant itself is completely secure.
