Respectfully, I ask you to consider Hosea 5:15.
Hosea 5:15 is a warning from God concerning their disobedience (Ephraim and Judah to be exact). But this isn’t the destruction of Judaism. Because in the very next verse, 6:1, they repented and returned.
Adam Clarke’s commentary on Hosea 6:1: “ When God had purposed to abandon them, and they found that he had returned to his place-to his temple, where alone he could be successfully sought; they, feeling their weakness, and the fickleness, weakness, and unfaithfullness of their idols and allies, now resolve to "return to the Lord;" and, referring to what he said, Hos 5:14: "I will tear and go away;" they say, he "hath torn, but he will heal us;" their allies had torn, but they gave them no healing. While, therefore, they acknowledge the justice of God in their punishment, they depend on his well-known mercy and compassion for restoration to life and health.”
Hosea 5 and 6 do not refer to the destruction of Jerusalem. Jesus prophesied about this (as did Daniel). Jesus’ prophecy is in Matthew 24.
Roman general (later, emperor) Titus destroyed Jerusalem in 70 AD. The Roman troops destroyed the temple as well as all the genealogical records. These records enable Jews to trace their ancestry back to Abraham. If they could trace their ancestry to Abraham then they could claim the promises to Abraham’s descendents in Genesis 12. Once these records were gone no Jew could verify the lineage. Judaism was effectively dead.
Some people (who don’t know their Bible) make the false claim that just because someone claims to be a Jew, they have God’s eternal promises for salvation, etc. That’s nonsense.
Judaism was already totally corrupt by the time Christ lived. For example, an encounter that Jesus had with Jewish leaders in Mark 7:6-8: “Well hath Esaias prophesied of you hypocrites, as it is written, This people honoureth me with their lips, but their heart is far from me. Howbeit in vain do they worship me, teaching for doctrines the commandments of men. For laying aside the commandment of God, ye hold the tradition of men, as the washing of pots and cups: and many other such like things ye do.”
John the Baptist also told them, “And think not to say within yourselves, We have Abraham to our father: for I say unto you, that God is able of these stones to raise up children unto Abraham.” (Matt 3:9-10) Already, at the time of John the Baptist, he was dispelling the fable that being a Jew was anything special.
Jews reject Christ. Reform Jews reject God. They’re mostly atheist. And for anybody to suggest the idiotic notion that they’re going to be saved (unless they denounce religious error and become faithful New Testament Christians) is preposterous. That would make God a respecter of persons which, He is not. (Acts 10:34)
