"His initial declaration is affirmative and without hesitation: “Lord, I believe.” I would say to all who wish for more faith, remember this man! In moments of fear or doubt or troubling times, hold the ground you have already won, even if that ground is limited.

So be kind regarding human frailty—your own as well as that of those who serve with you in a Church led by volunteer, mortal men and women. Except in the case of His only perfect Begotten Son, imperfect people are all God has ever had to work with. That must be terribly frustrating to Him, but He deals with it. So should we... when the infinite fulness is poured forth, it is not the oil’s fault if there is some loss because finite vessels can’t quite contain it all. Those finite vessels include you and me, so be patient and kind and forgiving

A 14-year-old boy recently said to me a little hesitantly, “Brother Holland, I can’t say yet that I know the Church is true, but I believe it is.” I hugged that boy until his eyes bulged out. I told him with all the fervor of my soul that belief is a precious word, an even more precious act, and he need never apologize for “only believing.”
...
Hope on. Journey on. Honestly acknowledge your questions and your concerns, but first and forever fan the flame of your faith, because all things are possible to them that believe."
Elder Holland
