I do teach in a bible school so we use the adult teaching materials. The Study from these books have really whipped up their enthusiasm, and they are even more eager to learn. The students really ask such thought provoking questions that make me also to sit down and study to always be ahead of them in knowledge. Some of the students are pastors of some small churches who are not affiliated to any Christian organization body. Because of this, their approach to church activities have been rather myopic. But these materials have challenged them. Some are developing foresight and insight into proper doctrinal issues. They are now learning the way of systematic teaching and learning. They never stop thanking and blessing you all.
