Why spoken, rather than
written words?

2/3 of the world’s population learns through spoken, not written, words.

Oral communities rely primarily on spoken means of communication, preferring to pass along knowledge and traditions from one generation to the next through verbal communication such as stories, songs, poems, and dramas – this is their preferred learning style. Yet most Christian discipleship resources have been produced for literate learners, informed by a Western cultural worldview. 

If you and nine of your friends made up the world’s population, about seven of you would be oral learners.
