Note: As the Church has said, the manual has been prepared as the primary source of lesson material. These supplements, from general conference addresses, are meant only as a complement to your study on this lesson’s topic.
Supplement is from President Henry B. Eyring's talk, "Adversity" from the April 2009 General Conference:
My purpose today is to assure you that our Heavenly Father and the Savior live and that They love all humanity. The very opportunity for us to face adversity and affliction is part of the evidence of Their infinite love. God gave us the gift of living in mortality so that we could be prepared to receive the greatest of all the gifts of God, which is eternal life. Then our spirits will be changed. We will become able to want what God wants, to think as He thinks, and thus be prepared for the trust of an endless posterity to teach and to lead through tests to be raised up to qualify to live forever in eternal life.
It is clear that for us to have that gift and to be given that trust, we must be transformed through making righteous choices where that is hard to do. We are prepared for so great a trust by passing through trying and testing experiences in mortality. That education can come only as we are subject to trials while serving God and others for Him.
In this education we experience misery and happiness, sickness and health, the sadness from sin and the joy of forgiveness. That forgiveness can come only through the infinite Atonement of the Savior, which He worked out through pain we could not bear and which we can only faintly comprehend.
It will comfort us when we must wait in distress for the Savior’s promised relief that He knows, from experience, how to heal and help us.
