President Dieter F. Uchtdorf, October 2017, “Bearers of Heavenly Light”

Whatever causes our spiritual ailments, they all have one thing in common: the absence of divine light.

Darkness reduces our ability to see clearly. It dims our vision of that which was at one time plain and clear. When we are in darkness, we are more likely to make poor choices because we cannot see dangers in our path. When we are in darkness, we are more likely to lose hope because we cannot see the peace and joy that await us if we just keep pressing forward.

Light, on the other hand, allows us to see things as they really are. It allows us to discern between truth and error, between the vital and the trivial. When we are in the light, we can make righteous choices based on true principles. When we are in the light, we have “a perfect brightness of hope”2 because we can see our mortal trials from an eternal perspective.

We will find spiritual healing as we step away from the shadows of the world and into the everlasting Light of Christ.

The more we understand and apply the doctrinal concept of light, the more we can guard against spiritual sicknesses that afflict or trouble us on every side and hand, and the better we can serve as energetic, courageous, caring, and humble bearers of the holy priesthood—true servants and disciples of our beloved and eternal King….

Every time you turn your hearts to God in humble prayer, you experience His light. Every time you seek His word and will in the scriptures, the light grows in brightness. Every time you notice someone in need and sacrifice your own comfort to reach out in love, the light expands and swells. Every time you reject temptation and choose purity, every time you seek or extend forgiveness, every time you courageously testify of truth, the light chases away darkness and attracts others who are also seeking light and truth.

D&C 88:67 – “And if your eye be single to my glory, your whole bodies shall be filled with light, and there shall be no darkness in you; and that body which is filled with light comprehendeth all things.”
