Likutei Moharan 62:3/ליקוטי מוהר"ן ס״ב:ג׳

13. {“For then I will turn [the speech of] the nations into pure speech, that they may all call out in God’ s Name and serve Him with one accord” (Zephaniah 3:9).} Faith is mainly perfected and adorned by bringing close in particular those who are distant, the aspect of “that they may all call out in God’s Name.” Even idolaters will draw close to the faith of the Jews “and serve Him with one accord.”
