"Lord, I believe, help thou mine unbelief"

What can we do in times of “unbelief,” or doubt or fear?

Mark 9:24

“When facing the challenge of faith, the father asserts his strength first and only then acknowledges his limitation. 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. In the growth we all have to experience in mortality, the spiritual equivalent of this boy’s affliction or this parent’s desperation is going to come to all of us. When those moments come and issues surface, the resolution of which is not immediately forthcoming, hold fast to what you already know and stand strong until additional knowledge comes.” Elder Holland  (“Lord, I Believe,” Ensign, May 2013, 93)
