Thomas S. Monson
"If you do not have a firm testimony of these things, do that which is necessary to obtain one. It is essential for you to have your own testimony in these difficult times, for the testimonies of others will carry you only so far. However, once obtained, a testimony needs to be kept vital and alive through continued obedience to the commandments of God and through daily prayer and scripture study” (“The Power of the Book of Mormon,” Ensign, May 2017).
