Everyone is a teacher and everyone can learn to teach better. That is the theme and substance of Teach Ye Diligently, a book that has become one of the premier resources on gospel teaching since its initial publication in 1975. A teacher by profession, President Boyd K. Packer of the Quorum of the Twelve Apostles draws upon personal experiences and observations in the classroom, as a teaching administrator, and in his own family to provide insightful interpretations of teaching principles that can help everyone who teaches in any type of situation.

There are suggestions to help the classroom teacher maintain discipline, provide a climate conducive to learning, and principles to aid the learning process. For parents as well as those called formally to teach, there are suggestions on how to make difficult subjects more easily understood, how to address the hard-to-answer questions, and how to get the attention of students.
