Of the Presidency of the Seventy
The Holy Ghost is the third member of the Godhead, and with the Father and the Son, He knows all things.
Sometime later that night I came to know for myself for the first time in my life that God and Jesus are real. I did not hear an audible voice nor see a heavenly being. I knew in the same way you too may have come to know—which is “by the unspeakable gift of the Holy Ghost” (D&C 121:26) and the spirit of revelation (see D&C 8:1–3) speaking peace to my mind (see D&C 6:23) and assurances to my heart (see Alma 58:11).
From that experience I witnessed the results of Alma’s counsel to “awake and arouse [my] faculties . . . to [conduct] an experiment upon [His] words” (Alma 32:27). These words or seeds have grown into trees, indeed giant trees of testimony. The process continues with more experiments upon the word, resulting in additional trees of testimony, now a veritable forest based on revelation through and by the Holy Ghost.
