And if it so be that you should labor all your days in crying repentance unto this people, and bring, save it be one soul unto me, how great shall be your joy with him in the kingdom of my Father!
And now, if your joy will be great with one soul that you have brought unto me in the kingdom of my Father, how great will be your joy if you should bring many souls unto me!
Doctrine and Covenants 18:15-16
"Just think of it, brothers and sisters, Jesus Christ suffered the pain of all men that you and I might have the promise of eternal life," said Elder M. Russell Ballard, in the October 1984 general conference. "Surely He can expect us to do His work that He has entrusted to us. Our Heavenly Father and His Beloved Son have not left us alone in this great work. They have promised to guide us if we will but ask them for help. . . . Many, if not all, of you will have special spiritual experiences as the Lord inspires you. I know from my own personal and family missionary experience that the Lord will enlighten your mind. He will sharpen your vision of this work by bringing names of non-members to your mind that you have never before regarded as potential members of the Church."
