How did knowledge of the one true God survive in ancient times?
God called Abraham, who then had a knowledge of Jehovah. That knowledge was passed on through Isaac, Jacob, and the twelve tribes. Consequently, Israel alone, during the period of the ancients, possessed a knowledge of the one true God, while all other nations followed pagan gods.
Les explains that after the call of Abraham, the knowledge of Jehovah was passed on through Isaac and Jacob and the twelve tribes, so that Israel alone, during the period of the ancients, had a knowledge of the one true God. All the rest had nothing but their pagan gods, which were usually female goddesses, gods of mythology, frogs, animals, the sun, or the moon. Later, Daniel, standing before a pagan king in all his splendor, declared that there is a God in heaven who reveals secrets and makes known what shall be in the latter days. Les stresses that all true prophecy centers on the nation of Israel, usually within a time frame, unlike the church age, for which there is no prophecy.
