The argument is made that, in evaluating the development of the biblical counseling movement, it is important to embrace the founding work of the first generation and the developing work of the second generation, being thankful for each. This work argues that the biblical counseling movement is one, single movement that has experienced conceptual, methodological, and apologetic development from a first, founding generation to a second, developing generation. It is further argued that this development has improved the theological foundation of the movement.
