You can find the text and history of The Lectures on Faith here
These lectures were originally included as the first part of the 1835 edition of the Doctrine and Covenants and were subsequently removed in the 1921 edition. I had never read them! As I started to read, I wished there were an audio version, so I made one myself!
The following lectures will be added as audio narrations by Debra Woods as completed:
Faith Defined - LECTURE FIRST
The Object of Faith - LECTURE SECOND
The Character of God - LECTURE THIRD
The Attributes of God - LECTURE FOURTH
The Godhead - LECTURE FIFTH
The Law of Sacrifice - LECTURE SIXTH
The Effects of Faith - LECTURE SEVENTH
