This is a wonderful DVD lesson with many applications. It makes a great addition to any individual or group bible study on covenants, communion, weddings, or biblical culture. In this lesson John explains the significance of salt in the eastern world and Jewish culture. He also explains how the biblical word's "Ye are the salt of the earth" are both a compliment and a commandment. With this clarification, the scriptures about salt, covenants and communion become more meaningful.
