After three years of learning to prepare expository sermons, the time finally came when the theology students were permitted to preach at the weekly chapel service. With several hundred students and staff in attendance, it was a difficult place to begin. One year, we were surprised by a student whom everyone knew as quiet. When the time came, she launched into an expert and rousing sermon. Her voice was commanding. The exposition was punctuated with vivid stories and illustrations from the local marketplace. Her points were skilfully repeated and punctuated with challenging questions which called for a response. The listeners were energised and engaged. When she sat down, no one had any doubt about what she had been called to do.
