Problem & Solution

We live in a broken world full of people who need a word of transformation. The message of healing can often be muddled—offering some truths, partial truths, and illusions. Yet, the Living Word alone holds the power to heal our brokenness. Utilizing oral methods rooted in hearing the Living Word brings healing and holistic transformation.

Our Ultimate Task: Retool 21st Century Leaders

  • Create model ministries beginning with one school, one church, and one mission organization that practice oral principles and methods.
  • Form replicable networks/cohorts of mission and educational leaders that foster a movement of orality-framed communication and instruction from the classroom to the pulpit to the grassroots.
  • Launch orality training cohorts beginning in Southeast Asia, Africa, and Latin America.
  • Become a leading force in orality research that supports and enhances orality.
  • Provide orality resources for cross-cultural workers, pastors, and teachers working among the oral majority.
  • Build a close network of orality experts who practice, research, and train regional leaders at all levels (especially grass-roots) in the art of oral instructional communication.
