“Subsequently, by our nurturing the seed carefully and by experiencing for ourselves, belief grows into confirmed faith, and faith grows into knowledge. Personal verification thereby occurs ‘in that thing’-meaning, in the principle which is specifically being obeyed and applied. Other principles or doctrines await the same process of personal verification.” (Gaining Spiritual Knowledge, p. 102)

"The prophet Alma presents an excellent explanation of the progressive steps by which one proceeds in his search for truth from a desire to experiment upon the words of the Lord to the ’exercise [of] a particle of faith, yea, even … no more than [a] desire to believe, let this desire work in you, even until ye believe in a manner that ye can give place for a portion’ of the words of the Lord; then by spiritual processes within one‘s own soul his knowledge and testimony is made ’perfect in that thing, and [his] faith is dormant…. ’ (Alma 32:27, 34.)
“As one reads this whole text, he finds clearly prescribed the way by which all may receive a testimony or ‘knowledge by revelation’ as defined above: first, desire; second, belief; third, faith; fourth, knowledge or testimony.” (Stand Ye In Holy Places, p. 194)
