What This Free Course Covers

This free audiobook course follows David Bercot’s The Kingdom That Turned the World Upside Down, a study of the kingdom of God as taught by Jesus and understood in early Christian history. It opens with the Crusaders’ siege of Jerusalem as a stark contrast to Jesus’ kingdom of love, enemy-love, and nonresistance.

From there, the chapters compare ancient Israel’s earthly kingdom with the present reality of Christ’s kingdom, then examine practical kingdom commitments involving wealth, honesty, marriage, divorce, enemies, government, and separation from the world.

The course also traces how Bercot believes the church’s witness changed after Constantine, how theology and church-state power reshaped Christian practice, and how later movements such as the Waldensians, Lollards, Anabaptists, and others carried forward kingdom themes. The lessons fit together as a historical and biblical argument that Jesus’ teachings are not optional ideals but the pattern for citizens of his kingdom.

Lesson-by-Lesson Guide

Chapter One: Holy War

  • Why begin a book on the kingdom of God with the Crusades?
  • How does the siege of Jerusalem contrast with Jesus’ teaching?
  • Did the Crusaders advance or harm the kingdom Bercot describes?

  • What made ancient Israel a right-side-up kingdom?
  • How were Israel’s blessings and punishments earthly and material?
  • Why does Bercot say Israel was not the final form of God’s kingdom?

Chapter 3, A Different Kind of Kingdom

Bercot explains John the Baptist’s announcement, Jesus’ preaching of the kingdom, and the four elements of a kingdom: ruler, subjects, domain, and laws. He emphasizes that Christ’s kingdom is already present, without earthly borders or military force.

  • What was the central theme of Jesus’ preaching?
  • Who are the subjects of the kingdom of God?
  • In what sense is the kingdom already present?
  • Why is this kingdom different from earthly kingdoms?

Chapter 4, Have You Made the Kingdom Commitments

Using the example of citizenship and allegiance, this chapter argues that Jesus requires undivided loyalty from kingdom citizens. Bercot introduces the Sermon on the Mount as the starting point for the kingdom’s values and laws.

  • What kind of allegiance does Jesus require?
  • Why does Bercot compare kingdom citizenship to naturalization?
  • How should Christians read the Sermon on the Mount?

Chapter 5, Changing Our View of Mammon

This lesson examines Jesus’ commands about treasure, mammon, contentment, and poverty of spirit. Bercot argues that kingdom citizens must let material things become servants rather than masters.

  • What does Jesus mean by not laying up treasures on earth?
  • Why does Bercot say no one can serve both God and mammon?
  • What does poverty of spirit look like in daily life?
  • How can materialism affect family and spiritual life?

Chapter 6, A New Standard of Honesty

  • Why does Jesus command his followers not to swear oaths?
  • What does it mean for yes to mean yes and no to mean no?
  • How does dishonesty damage Christian witness?
  • Why does Bercot treat false miracles as a serious problem?

Chapter 7, The Kingdom Laws on Marriage and Divorce

This lesson presents Bercot’s reading of Jesus’ teachings on divorce and remarriage. He argues that Jesus narrowed what had been permitted and calls readers to investigate the relevant passages honestly.

  • What did Jesus teach about divorce?
  • How does Bercot interpret Paul’s words in 1 Corinthians 7?
  • Why does this teaching offend many hearers?
  • Did Jesus expand or narrow earlier divorce permissions?

Chapter 8, Love My Enemies

Beginning a section on nonresistance, Bercot explores Jesus’ commands to turn the other cheek, go the second mile, and love enemies. He argues that these teachings touch everyday conflicts as well as war.

  • Why does Bercot call enemy-love the biggest stumbling block?
  • What does turning the other cheek require?
  • Is nonresistance the same as weakness?
  • How should Christians respond to enemies in ordinary life?

Chapter 9, But What If

This chapter addresses common objections to nonresistance, including self-defense, family protection, and military service. Bercot also appeals to early Christian writers who answered similar criticisms from pagan society.

  • What if someone threatens a Christian’s family?
  • Can love of family override Jesus’ commands?
  • How did early Christians answer charges that they would not defend the empire?
  • Can Christians divide allegiance between Christ and Caesar?

Chapter 10, But don't the Scriptures say

Bercot considers Scripture passages sometimes used to challenge nonresistance, including Jesus’ words about a sword, the centurion, Cornelius, and apostolic examples. He argues that these texts do not overturn Jesus’ kingdom commands.

  • What can be concluded from Cornelius’s conversion?
  • How did the early disciples respond to persecution?

  • In what sense are rulers God’s servants?
  • How does Satan relate to the kingdoms of this world?

  • How should believers use the Sermon on the Mount for self-examination?
  • What does Bercot mean by “kingdom Christians”?

  • Why does Bercot see Constantine’s support as spiritually dangerous?
  • How did church and state begin to mix?

  • Why does Bercot appeal to John the Baptist’s example?

  • How did papal power grow after the fall of Rome?
  • Why does Bercot discuss corrupt and violent medieval practices?
  • Can societal norms excuse disobedience to Jesus’ commands?

  • What was decided at Chanforon?
  • Why does Bercot see this meeting as the end of their kingdom witness?

  • Why does he say Christianity is relational rather than merely theological or mechanical?

About the Book

Cover of The Kingdom That Turned the World Upside Down by David W. Bercot

Recovering Jesus' core message about His kingdom

  • Author: David W. Bercot
  • First published: 2003

  • ISBN: 9780924722172

If someone were to ask you the theme of Jesus' preaching, what would you say? Man's need for salvation? The character of God? Heaven? Love? All are wonderful Biblical truths — but none of them were the theme of His teaching. The theme of Jesus' message was the kingdom of God. Wherever He went, Jesus preached about the kingdom.

Yet today, the kingdom is rarely discussed — and when it is, it has been so spiritualized and reduced that it bears little resemblance to what Jesus actually taught. We hear about the kingdom as a future hope, a heavenly destination, a poetic image. But in The Kingdom That Turned the World Upside Down, David Bercot takes the reader back to Jesus' actual teachings — teachings that have too often been forgotten or watered down.

Bercot describes the radically new laws of the kingdom and its upside-down values: Love your enemies. Don't swear oaths. Don't store up treasures. Be willing to lose your life. There's no room in Christ's kingdom for superficial Christianity, for this is a kingdom that has historically turned the world upside down. Polished throughout with captivating illustrations, personal testimonies, and historical evidence, this book will challenge you to the core in your Christian walk.

About the author: David W. Bercot is a former evangelical-turned-Anabaptist attorney and historian who has spent four decades studying the writings of the early Christians (A.D. 90–325). He is the editor of the landmark Dictionary of Early Christian Beliefs and the founder of Scroll Publishing Co.

An absolutely life-changing book. As a young Christian raised in the mainstream Evangelical Church, this book turned my world upside down. At first I hated the message — but I could not escape it.

Jessica Greening, Scroll Publishing customer review

The best exposition of the doctrine of the kingdom I have ever read! I have already put together two sermons modeled after his arguments. And I must say, it was a tremendous success in my congregation.
