It was a childlike question, but the answer was as stunning as it was profound. If God is light, what do the primary colors of the rainbow’s spectrum signify? The Gospel of John declares in eight mysterious signs that God is light and Jesus Christ in the flesh was God sent to bring the light of true life to us. These enigmatic signs of light, semeion, imply the eight signs’ significance pointed to something other than what they appeared. The themes of John’s eight signs match the themes of the Feasts given to ancient Israel at Mount Sinai and a sequence of YHWH’s covenant names. Behold, I AM is a rich, in-depth study into God’s Holyday appointed times, His eight Festivals of Light, what they meant then, what they mean today, and how they are fulfilling prophecy. 

These Are YHWH's Feasts
Tracing God's Calendar from Creation to New Creation

What if the Feasts of YHWH are more than ancient observances—what if they trace the entire biblical journey from Creation to New Creation?

After more than fifty years of studying and observing the biblical Feast Days, Joyce Lynn Wulf brings together Scripture, Hebrew word studies, Ancient Near Eastern history, the Hebrew calendar, numerical patterns, and the structure of the Pentateuch to explore the appointed times of Leviticus 23.

Beginning with the rhythms established in Genesis, These Are YHWH’s Feasts follows Passover, Unleavened Bread, the Feast of Weeks, Trumpets, the Day of Atonements, Tabernacles, and the Eighth Day through the biblical story. Along the way, familiar passages take on new depth as connections emerge between creation, Exodus, covenant, sacred time, the Tabernacle, Israel’s wilderness journeys, the Gospel of John, and the work of Yeshua.

Rather than treating the Feasts merely as historical festivals or isolated prophetic symbols, this study places them within the worldview of the biblical writers and asks what they reveal about God’s character, His covenant purposes, and humanity’s transformation into His image.

Rich with charts, Hebrew and Greek studies, Scripture connections, historical context, and recurring numerical patterns, this book is designed for readers who want to go beyond a surface study of the biblical Feasts and explore the architecture woven throughout Scripture.

Awake Not the Hungry

Imagine you are born deaf, blind, unable to speak, with doctors saying you will only live a few months.  And then imagine sensing the hand of a loving God reaching toward you as if to say, “I have a purpose for your life, and I will be with you every day of your journey.”

Matthew Andreas Wulf struggled for life from birth with a rare disorder Zellweger’s Syndrome.  His body profoundly affected, he worked with tenacity to learn, to discover, to achieve, to live.  As he reached up to grasp the hand of God in a hope that will amaze, Matthew kept a record of his writing over six years of his school life, showing his progression in both his learning and faith.

Out of this, he formed the book, Awake Not the Hungry, as an effort to make his short life meaningful and inspiring to others who learn of him, and those who struggle with disabilities and challenges bigger than they are.  Matthew wants most of all to share an unusual life that has developed his belief in the power of God and His purpose for every life.
