Well, that's certainly true, but Weingrad's makes the point, correctly, I think, that in the divergence of the Christian and Rabbinic Jewish traditions, the dualist "battle between Good and Evil" part tended to be played up in Christianity while it faded in Rabbinic Judaism.
Yearning for the Messiah if anything got more important between Talmudic and medieval times -- but it's hard to find much universalized Forces of Evil. There's no hugely powerful Dark Lord against whom the (relatively weak) forces of Good must battle, none of Lewis's sense that the Earth is hostile occupied territory where the Devil reigns supreme.
Instead there was the sense of the world as broken, as corrupt, as fallen. It was a place, certainly, where evil abounded -- but not Evil. There was no lack of suffering to motivate the yearning for a Redeemer. But there was only one Lord, from whom both dark and light came. The climax of the Jewish story is when God decides to send the Messiah -- not any battle that the Messiah would thereafter fight against an Adversary, none of the dualist book-of-revelations epic fantasy struggle which obsessed Christians.
