"It’s
natural to have questions—the acorn of honest inquiry has often
sprouted and matured into a great oak of understanding. There are few
members of the Church who, at one time or another, have not wrestled
with serious or sensitive questions. One of the purposes of the Church
is to nurture and cultivate the seed of faith—even in the sometimes
sandy soil of doubt and uncertainty. Faith is to hope for things which
are not seen but which are true.7
Therefore, my dear brothers and sisters—my dear friends—please, first doubt your doubts before you doubt your faith.8 We must never allow doubt to hold us prisoner and keep us from the divine love, peace, and gifts that come through faith in the Lord Jesus Christ."
