Whatever the job that you have, the likelihood of you having received some training specific to that role is very high. It may have been on-the-job, 3+ years of formal study or even a half day of working out where things are but you have received some form of learning around the organisation/company you work for and how to do the task you’ve been given.
The same applies to overseas mission service. You may have already received the training for the professional skills you can offer, but mission service is far more than just your work life. To make the Good News known then we also need the skills and tools to do this appropriately and wisely alongside ensuring we understand the context in which we are working and living.
So training for mission is an important part of the preparation process. Each agency will have their own requirements about Bible/Theology training for long term service, however most recommend some level of study either prior to departure, while on the field or during a first home assignment time. The amount and level of training will also be reflective of the role that each individual has on the field. Whatever the role, it is still recommended that cross cultural training and orientation is undertaken. Options for training include formal accredited courses and qualifications and shorter focused study programmes.
