ELI5: Explain Like I'm 5

Christian reconstructionism

Christian Reconstructionism is a philosophy that believes that the Old Testament law should be followed by Christians today in its entirety. This means that Christians should live their lives according to the laws God gave in the Bible like not working on the Sabbath day, not kidnapping, respecting their parents and generally doing what God wants. It is a way for Christians to follow God's plan for them in the Bible.
