Every year the students went out on mission into areas of the country that were little evangelised. One year, we had a student who had been involved in traditional witchcraft before he became a Christian. As a result, he was not afraid to preach in houses where others held back. In one such house, a medicine man challenged him to a duel. He claimed superpowers that enabled him to eat unpalatable foods without harm. If the student’s God could protect him, then the medicine man would also become a Christian. Our student had 24 hours in which to fast and pray. He then went back to the house and joined the man in the meal. When nothing untoward happened, the medicine man declared that the student’s God had overcome his own powers and true to his promise, he became a Christian.
