Valerie Moody taught the biblical festivals and a Hebraic perspective of end time prophecy on GLC. While celebrating the feasts and Sabbath, she discovered that no feast book answered all of her questions. She wrote The Feasts of Adonai to answer important questions about each festival, its biblical foundation, purpose, spiritual meaning, prophetic fulfillment, and ways for believers to celebrate. The book has been a bestseller since 2002. One Arizona reader said: "This is the best feast book out there, and I have them all!"
