The Seed and the Inheritance is a direct, Scripture-driven examination of one of the most contested questions in modern Christianity: Who are the true heirs of God’s promises?

Drawing exclusively from the King James Bible, David Michael Curtis presents a systematic challenge to two dominant systems—Dispensationalism and Sabbatarianism—by returning to a single, testable foundation: gather every verse, believe what it says, and force full harmony.

At the center of this work is Joint-Heir Theology—the biblical claim that every promise made to Abraham belongs to one Seed alone, Jesus Christ, and that all believers inherit those promises only by being in Him.

This book walks the reader through:

• The legal framework of inheritance in Scripture
• The distinction between the “Seed” and the “seeds”
• The role of the Law as a schoolmaster, not a pathway to righteousness
• The difference between covenant promise and covenant mixture
• The errors behind modern systems that divide Israel and the Church
• The conflict between grace-based inheritance and law-based maintenance

Structured in 100 summary answers and 100 in-depth studies, this work allows readers to move quickly through core doctrines or stop and examine each issue in detail.

This is not a book of commentary or tradition. It is a test.

Every claim can be verified. Every conclusion can be challenged. The reader is invited to lay aside denominational systems, gather the verses, and determine whether the Scriptures truly speak with one unified voice.

If the promises belong to Christ alone, then the question becomes unavoidable:

Are you trusting in a system—or are you in the Seed?
