The Lamb Swap

What happens when an everyday man—doubting, questioning, and deeply ordinary—encounters the profound mysteries of both God and the universe?

Mark S. Harris isn’t a physicist or a theologian. He’s an ordinary guy from Saint Jacob, Illinois — co-founder of Equip Products, Inc., an adaptive fitness gear company for veterans and trauma survivors, husband, horse rider, and lifelong seeker navigating faith amid chaos.

In The Lamb Swap, Mark S. Harris invites readers into his raw, honest pilgrimage: a life transformed by swapping his flawed, human perspective for the light of the divine Lamb.

From his home in small-town Illinois, Mark draws from personal struggles, moments of doubt, and unexpected revelations to show how timeless Christian truths align strikingly with modern physics.

From the illuminating power of light (both literal and spiritual) to the mind-bending paradoxes of quantum theory, relativity, and the fabric of reality, this memoir reveals surprising harmonies between scripture and science. It’s not a debate or a textbook—it’s one ordinary guy’s story of discovery: how wrestling with the laws of the universe deepened his encounter with the Creator, turning skepticism into awe and ordinary life into sacred purpose.

Perfect for believers seeking intellectual depth, seekers curious about faith-science intersections, or anyone pondering life’s biggest questions. The Lamb Swap shows that faith isn’t blind—it’s illuminated by truth from every direction.

Discover how an “ordinary guy” found extraordinary hope in the swap between shadow and light.
