Who are the two houses of Israel? Historically, they were the Northern Kingdom (house of Israel) and the Southern Kingdom (house of Judah). Today, they are known as the names of Christianity (house of Israel) and Judaism (house of Judah). Why are the two houses of Israel divided? How and when will they be reunited? This book examines some of the doctrinal issues that have historically divided the two houses of Israel like Torah, grace, Sabbath, who is the Jewish Messiah (Mashiach) and eschatology (study of the last days). It will also examine how the Israel/Arab peace process is associated with the reunification of both houses of Israel in the end of days.
