The Four Earmarks of Discipleship have proven to be one of the most effective set of teaching tools in helping others understand what Discipleship is and what it isn’t.  I first came across the Four Earmarks of Discipleship in a book by Greg Ogden titled Transforming Discipleship: Making Disciples a Few at a Time. Discipleship is a pedagogy (a way of teaching) and when we are striving to form disciples, these four earmarks are what are needed to create an ideal atmosphere for Discipleship.

Eric Gallagher writes about these and the other fundamentals in his book Discipleship Focused Youth Ministry.
