Mark Biltz did not set out to become one of the most recognized voices in biblical prophecy. He set out to understand what most people had stopped looking for. In 1999 he founded El Shaddai Ministries in Washington State - a congregation that today livestreams its weekly services to more than two hundred cities across twenty nations. But it was his deep dive into the Hebrew language, the biblical feasts, and God's prophetic calendar that brought him to global attention. In 2008, Biltz made a discovery that would reframe how millions of Christians read the end times : a series of blood moon tetrads - four consecutive total lunar eclipses falling precisely on Passover and the Feast of Tabernacles - that historically coincided with pivotal moments in Jewish history. He traced them to 1493, 1948, 1967, and 2014-2015. The pattern was not coincidence. It was appointment. His book Blood Moons became a bestseller and sparked a worldwide conversation about the relationship between God's calendar and prophetic fulfillment. Since then, Biltz has authored multiple books - including God's Day Timer and Decoding the Antichrist and the End Times - and lectured at conferences and congregations in twenty-five nations on five continents. The Final Tyrant is his most urgent message yet. Not a theory about the future - a warning about the present. El Shaddai Ministries: esm.us
