Today's podcast is taken from a BYU devotional in 2015 by brother Mark B. Colton, who is an associate professor in the BYU Department of Mechanical Engineering. In this devotional, brother Colton addresses the importance of a testimony of the gospel of Jesus Christ. A testimony is one of our most your most valuable possessions; as such Satan seeks to erode our faith. We must fight to keep our testimonies with the same tenacity that we fight for other things in life.
