What are Indigenous Churches Like?

It seems that the only optimism that can be generated with respect to reaching the millions without Christ is not to be found in the number of missionaries who go to the field, but in the rapid multiplication of Christianity among nationals reached by nationals. How effective are indigenous churches? How free are indigenous churches? How numerous are they? Is the use of the term “indigenous church” simply lip service to a concept? [Question by Frank E.
