Why don’t the people who are called prophets tell the Jews this?

“Convert to Protestant Christianity, ‘But I say, Did not Israel know? First Moses saith, I will provoke you to jealousy by them that are no people, and by a foolish nation I will anger you.’ (Romans 10:19), we’re here to ‘provoke them to jealousy’ (Romans 11:11). We know that ‘these also now not believed, that through your mercy they also may obtain mercy.’ (Romans 11:31). This is the mercy, hear us; this is the refreshing, join us.”
