“The Gospel [Shall] Roll Forth . . . Until It Has Filled the Whole Earth”
Doctrine and Covenants 65:2
2 The keys of the kingdom of God are committed unto man on the earth, and from thence shall the gospel roll forth unto the ends of the earth, as the stone which is cut out of the mountain without hands shall roll forth, until it has filled the whole earth.
Elder Richard E. Cook said:
“President Kimball once called missionary work the lifeblood of the Church, and indeed it is. It’s not only because new converts give the Church vitality and strength, but the missionaries themselves gain a new measure of vitality and strength as they participate in the converts’ commitment to Christ. This vitality and strength is a mighty force, an instrument in God’s hands to cause the gospel to roll forth and fill the whole earth as Daniel saw in his dream (see Daniel 2:31–45; D&C 65:2).”
