Spirit of Truth

D&C 50:13-14, 17-23

Unto what was I ordained? To preach the the Lord's gospel through the Comforter which teaches the truth.
I know that by the Spirit truth will be manifested. I have bore my testimony of the gospel and every time I can feel the Spirit whispering to me that it is true. A few months ago I played a variation of Joseph Smith's Prayer, A Poor Wayfaring Man of Grief, and Praise to the Man on the piano in sacrament. As soon as I was done and walked back to my parents, and not hearing a single sound due to the reverence, I felt a swelling and a burning in my bosom which filled and consumed my whole soul. I knew that right then that Spirit had testified unto me that Joseph Smith did see God the Father and Jesus Christ, that what he did for humanity was great, and that he his a prophet of the Lord.
This experience has taught me that the Spirit can do marvelous things in teaching and guiding. My goal as a missionary is to seek ways to keep and invite the Spirit at all times off and on my mission so as when I'm faced with the opportunity to teach an investigator, I may be able to teach with the Spirit as my companion.
