"As we truly humble ourselves, we will be blessed with this gift to have faith and to hope for things which are not seen but are true (see Alma 32:21). As we experiment upon the words given to us by the scriptures and the living prophets--even if we only have a desire to believe--and do not resist the Spirit of the Lord, our souls will be enlarged and our understanding will be enlightened (see Alma 32:26–28)."
-Dieter F. Uchtdorf
