“The only teaching that is teaching is that which produces desirable changes in the life of the learner.”
“The only learning that changes conduct significantly is learning that is self-discovered and self-appropriated.”
“Never tell anyone anything that you can lead him to discover for himself.”
Keep in mind the purpose of your teaching. Have an aim for each lesson, and evaluate your achievement by the spiritual transformation of your pupils. You are not simply teaching the Bible, but you are teaching men and women the Bible.
