"Every word that proceedeth from the mouth of Jehovah has such an influence over the human mind—the logical mind—that it is convincing without other testimony. Faith cometh by hearing." (Joseph Smith, HC 5:27)
"FAITH comes by hearing the word of God, through the testimony of the servants of God; that testimony is always attended by the Spirit of prophecy and revelation." (Joseph Smith HC 3:25)
"Faith comes by hearing the word of God." (Joseph Smith, HC 5:18)
The Holy Ghost removes carnal desires, replaces with desire to do good.
Faith comes by hearing the word of God. (This presupposes the speaker is in possesion of it, or in other words, is speaking by the power of the Holy Ghost)
Gift of prophecy is the hallmark of having the Holy Ghost.
"And they all cried with one voice, saying: Yea, we believe all the words which thou hast spoken unto us; and also, we know of their surety and truth, because of the Spirit of the Lord Omnipotent, which has wrought a mighty change in us, or in our hearts, that we have no more disposition to do evil, but to do good continually.
"And we, ourselves, also, through the infinite goodness of God, and the manifestations of his Spirit, have great views of that which is to come; and were it expedient, we could prophesy of all things.
"And it is the faith which we have had on the things which our king has spoken unto us that has brought us to this great knowledge, whereby we do rejoice with such exceedingly great joy." (King Benjamin, Mosiah 5:2-4)
"Let us here observe, that three things are necessary, in order that any rational and intelligent being may exercise faith in God unto life and salvation.
"First, The idea that he actually exists.
"Secondly, A correct idea of his character, perfections and attributes.
"Thirdly, An actual knowledge that the course of life which he is pursuing, is according to his will. For without an acquaintance with these three important facts, the faith of every rational being must be imperfect and unproductive; but with this understanding, it can become perfect and fruitful, abounding in righteousness unto the praise and glory of God the Father, and the Lord Jesus Christ." (Joseph Smith, Lectures on Faith, Third Lecture. Emphasis in original)
"During his message on the Holy Spirit, the hunger in my soul became palpable. I could hardly stay in my seat. “Yes!” I thought. “This is what my life is missing. This is what I need!” (After all, I had already tried everything else). I had been filled with the Spirit once before, had spoken in tongues, but probably not in 10 years. When the evangelist gave the altar call for those wishing to receive the Holy Spirit, I went forward, despite some of the curious stares I got.
"Again, I didn’t shout. I didn’t dance around. I didn’t shake or lose control of my body. I didn’t fall out in the floor. In fact, the evangelist had all of the respondents sit down on the first row. He didn’t yell, spit, blow on anyone or try to push them down. He just prayed very simply for people to receive the gift of the Holy Spirit. Before he even reached where I was sitting, I began (quietly) praying in tongues.
"That night, a great sense of peace flooded my heart. I found myself singing in tongues while driving down the road a couple of days later. The relief I felt was so sweet.
"It was about two weeks later, after I had returned home to my husband, that I realized something incredible: there was no pain or anger in my heart anymore! All the dark memories I had of abuse and ridicule no longer hurt me. I had forgiven all of my abusers 100%, including the man who had molested me! The same-sex attraction I had been struggling with was gone, too. I no longer had any desire to look at porn or entertain fantasies about anyone other than my husband. I decided to start attending church more regularly–every week if I could. (April Kelsey. My Faith Experience, part 4)
