The key to a relationship is communication, particularly speech communication. When it comes to our relationship with God, prayer – especially intimate, private personal prayer – is the best means of communicating. In that respect, personal prayer is the language of emuna. This type of prayer doesn't appear in any prayer book. It is written on the innermost walls of a person's heart. "The Language of Emuna," Rabbi Lazer's inspiring new book, shows how life-enriching personal prayers can be for anyone, no matter what their background might be.
