Deuteronomy 21 - Reformation | Looking Back, Looking Forward


Deuteronomy 21 shows that true reformation begins with revived hearts and then reshapes families, justice, discipline, and society under God’s wisdom.

What is the difference between revival and reformation? In this Deuteronomy 21 study, Paul J. Bucknell explains how revived hearts can lead to lasting godly change in families and society. Deuteronomy 21:15-21 may seem difficult at first, but these laws reveal God’s concern for justice, family responsibility, protection of the vulnerable, and the danger of unchecked rebellion. This study calls believers to examine their values, strengthen family life, discipline children wisely, and seek true reformation through God’s Word and the transforming power of Christ.

Teaching Points

  • Revival renews the heart, while reformation describes the long-term cultural changes that flow from renewed hearts.
  • A society declines when it separates values from God’s life principles.
  • God redeemed Israel so that His people could live in His presence and under His blessing.
  • Old Testament laws reveal God’s values, even when they are not directly applied as civil law under the New Covenant.
  • Deuteronomy 21:15-17 protects the vulnerable by restraining family favoritism and inheritance injustice.
  • Deuteronomy 21:18-21 warns that unchecked rebellion harms families, victims, and society.
  • Strong families, wise discipline, faithful marriages, and gospel hope are central to lasting social reformation.

Deuteronomy 31 Life’s Calling and Faith

Deuteronomy 31 brings Moses to the end of his earthly journey and Joshua to the beginning of a new calling. In this study, Paul J. Bucknell reflects on how these two movements meet to clarify our life purpose, strengthen our faith, and teach us to move forward under God’s leading. The lesson calls believers to evaluate their whole life before the Lord, reject both pride and despair, and courageously join God in the work He has prepared.
