In Christianity and Islam, one must join the faith in order to be saved.That is not the case in Judaism. Judaism seeks no converts because Judaism holds that non-Jews do not need Judaism, since all people, including non-Jews, already have a binding Covenant with God that exists outside of Judaism.That Covenant is the Seven Laws of the Sons of Noah. And Judaism holds that if a non-Jew but follows these seven simple laws, instead of the far more restrictive 613 laws of Judaism, one has done enough to save himself, and therefore doesn't need Judaism.But why should a Christian listen or pay heed to what Judaism informs him is his obligation and reward. To Christians, Judaism is null and void and defunct, and made so by the New Covenant of Jesus, which has replaced and surpassed the Old Covenants of Abraham and Moses. Why then should any Christian listen to what Judaism tells him he should do?This book tells why. This book establishes a number of little known facts.1) From evidence furnished in the Christian scriptures, this book demonstrates that the founders of the original Jerusalem Church of Jesus, these disciples who had known Jesus personally and in the flesh, understood the Seven Laws of the Sons of Noah and adopted these laws as the operating law of their church. And therefore, so this book argues, if the Seven Laws were good enough for the very founders of Christianity, the Seven Laws should therefore be good enough for all living Christians today.2) This book shows why certain passages in the Christian scriptures cannot at all be correctly understood by Christians unless and until Christians know about the Seven Laws, but once Christians do understand these Seven Laws, these passages in their own scriptures will jump out at them with unexpected clarity. Christians should therefore study this book in order to gain new insights into their own religion.These passages include the narratives of The Good Centurion, Cornelius the Good Centurion, the conversion of the first 3,000 Christians on the first Pentecost, the accounts of Paul's missionary journeys, and the accounts of both trials of the Apostle Paul.This book is therefore indispensible to all Christians who seek to know their own religion better.
