A Discovery Bible Study (DBS) is a disciple-making tool used to help launch gospel movements—sometimes known as Disciple Making Movements or DMM—around the world. It’s a great way to share the good news of Jesus and form new disciples in an interactive, Holy Spirit-led format. In a DBS group, spiritually-interested people read a Bible story together, discover what it says, and then are challenged to immediately live out what they learned and share it with someone else.
