Every week a missionary comes to spend two days at Cornerstone. They are involved in all kinds of mission work and are from many different mission organisations. They share about the reality of life as a missionary; the ups and the downs, the tough times and the times of joy and seeing results. Students keep a logbook, in which they reflect on the presentations. They also interact in more depth with some of the visiting missionaries by interviewing them. This unit aims to give students a realistic picture of life as a missionary, tools for handling the challenges and ideas for their future ministry.
