Well when they believed directly on Jehovah for personal salvation they believed in the Son too, before the Son was revealed as Jesus. They won’t be saved by law keeping, something that the Jewish people were already warned that they couldn’t do... at the time the law was given! The covenant pertains to earthly existence as a race not to eternal salvation, to which some will fail to attain because they won’t believe directly on Jehovah (revealed as Jesus or otherwise) for personal salvation. Also the biblical pattern strongly suggests, and I believe it is a truth, that Jews who believe on Jehovah for salvation will — not might, will — recognize who Jesus is at some point, which solves the conundrum of supposed Jesus-less salvation.
Indeed.
Look at Hosea 5:15. It states:
I will go and return to my place, till they acknowledge their offence, and seek my face: in their affliction they will seek me early.
First, this is in the Old Testament. Second, just who is this person who says he will return to his place? It's Christ Himself! Third, you can't return to a place that you hadn't left. Fourth, what offence is acknowledged and who's acknowleging? Christ's crucifixion, and a remnant of the children of Israel is who.
Yes, the time is soon coming where they will seek His face in dire affliction. When they do this, He will return.
Now, this is truly why Satan has it out for the Jewish people and the nation of Israel. Satan does NOT want their petition to be raised.
