A D-Group is a gender-specific closed group of 3 to 5 believers (including the leader) who meet together at least once a month for the purpose of accelerated spiritual transformation. 

While LifeGroups exist for the purpose of connecting, A D-Group, on the other hand, consists of believers who desire a deeper walk with Christ. It is not evangelistic in its form or function, but in its fruit: it makes disciples who will then go on to make more disciples.

The format of a D-Group is not one of a teacher-student, but a roundtable discussion. In their book The Invested Life, Joel Rosenberg and T.E. Koshy suggest that a discipleship relationship is “more personal, more practical, and more powerful. A teacher shares information, while a discipler shares life; a teacher aims for the head, while a discipler aims for the heart; a teacher measures knowledge, while a discipler measures faith; a teacher is an authority, while a discipler is a servant; and a teacher says, ‘Listen to me,’ while a discipler says, ‘Follow me.’” This blueprint, sketched by Jesus Christ through His personal example, is how discipleship is accomplished in the lives of believers, and, ultimately, within the local church. When this plan is followed, those involved will participate in three dynamics that result in growth in their personal lives, as well as in the Kingdom: connecting because of the Gospel, growth in the Gospel, and influence with the Gospel.
