Deuteronomy 30: Restoration Promised

Read somewhere that the restoration promised here was fulfilled somewhere in Ezra. The restoration which it is said that it should take place in 20th Century is predicted somewhere ahead after the Deuteronomy.
The restoration promised here denotes one more fact that the organism of this faith viz. “Judaism” is very unique and community specific. Independently at ideological level it does not have a strong universal appeal. The question is how this community specific faith is being interpreted and was interpreted by Marathi Protestant Christians.
