Many modern missionaries see themselves as professionals who are already experts, having been allowed by their agencies to train themselves. Some are more mature individuals who have had successful careers, and perhaps the assumption is made that they automatically have the skills they need for church planting.
And yet, it has become clear to many of us in the past few years that truly learning cross-cultural church planting must be done in the field.
While books can give guiding principles to elucidate various approaches, and classroom discussions can impart much wisdom, true cross-cultural church planting has so much variety that it must be learned through experience.
Very few if any jobs in Christian ministry can compete with cross-cultural church planting for sheer difficulty.
