Hammer and Fire

A New Covenant Theology Rooted in the Kingdom of God

A Theology That Breathes With the Fire of the Spirit

For too long, Spirit-filled believers have been handed theological systems that make no room for the very life they carry. Too often it’s all lecterns and lectures—ideas without ignition, doctrines without demonstration. What’s missing is the pulse of the Spirit, the supernatural vitality that belongs not only in classrooms but in the streets and alleyways where real people live and real faith is tested.

This book seeks to change this.

In this groundbreaking and accessible work, J.D. King bridges the gap between head and heart, truth and power, doctrine and experience. He presents a Kingdom-centered, New Covenant vision of God’s redemptive plan—one that fully embraces the miraculous, Spirit-empowered worldview of the early Church.

Far more than a doctrinal guide, this volume invites readers into a living theology—one that forms disciples who think deeply, live faithfully, and intercede powerfully.

Whether you’re a pastor, ministry leader, Bible teacher, or passionate believer longing for a faith that’s both intellectually rich and spiritually alive, this book will equip you to:

• Grasp the biblical foundations of a Spirit-filled worldview.
• Reclaim theology as a tool for revival, not mere speculation.
• See how covenant, kingdom, and Spirit weave together God’s redemptive story.
• Lead others with greater authority, clarity, and power.

Designed for classroom use but written for the broader Church, this is a must-have resource for anyone who believes theology should not only inform the mind but also ignite the heart.
