What Is Prophecy? | Ariel Blumenthal In this week’s Global Broadcast, Ariel Blumenthal explores what prophecy is, how it functions in both the Old and New Testaments, and what it means for believers today. He explains how prophets like Jeremiah primarily called the people to repentance, while warning of God’s impending judgment. Under the older covenant, a prophet was held to the highest standard of accuracy, punishable by death if what he prophesied did not come to pass. (Deuteronomy 18:20–22)
