"Be judicious in your use of commentaries and other nonscriptural sources of information."


("Judicious" means: "having good judgement or sense.")


"When preparing for Gospel Doctrine class, it is important that you seek inspiration and guidance from the Spirit of the Lord...

While preparing for class, pray for the Spirit to help you understand the scriptures and the needs of class members. The Spirit can also help you plan meaningful ways to discuss the scriptures and apply them to the present (1 Nephi 19:23). With the help of the Spirit, you will become an effective instrument in the hands of the Lord to teach his word to his children.

This manual is a tool to help you teach the scriptures...

During class, keep discussions focused on the scriptures. Be judicious in your use of commentaries and other nonscriptural sources of information. Class members should be taught to seek knowledge and inspiration from the scriptures and the words of the latter-day prophets.

The lessons have been designed to contain more information than you will probably be able to teach in one class period. Seek the Spirit of the Lord in selecting the scripture accounts, questions, and activities that best meet the needs of class members.

...Seek the Spirit’s guidance in deciding which questions to ask, how to organize them, and how to develop them. Class discussions should center on matters that help members come unto Christ and live as his disciples.

Covering all the lesson material is less important than helping class members better understand the scriptures and commit themselves to increased discipleship. If class members are learning from a good discussion, it is often helpful to let it continue rather than try to cover all the lesson material."
