Jesus Christ said, “I am the light of the world: he that followeth me shall not walk in [the] darkness, but shall have the light of life.”3
What does this mean?
Simply this: He who humbly follows Jesus Christ will experience and share in His light. And that light will grow until it eventually dispels even the most profound darkness. – Dieter F. Uchtdorf, “Bearers of Heavenly Light,” Ensign (CR) November 2017
