This book deals with the identity of the Torah that Yahweh promised he would write on the hearts of New Covenant participants, as prophesied in Jeremiah 31:33 and understood later in New Testament times by Paul. This theological and exegetical monograph is an invaluable reference work and textbook for all theological seminaries and Christian religious departments of universities worldwide. Pastors and virtually all Christians interested in reading or researching Paul and the subject of Gospel/law controversy in biblical studies will benefit from it. The book's investigative study of the history of interpretation of the church's teaching on the subject from the early church to modern theological era, and Second Temple Judaism's writings on the topic, is unsurpassed. No work currently existing on this subject can compete with this book's historical survey and exegetical analysis, reading Jeremiah and Paul contextually on the issue.
