In a revelation given to Hyrum Smith, the Lord said: “And now, verily, verily, I say unto thee, put your trust in that Spirit which leadeth to do good—yea, to do justly, to walk humbly, to judge righteously; and this is my Spirit” (D&C 11:12).
When people respond to their consciences, when they seek alter and receive the fruits and gifts of he Spirit, they naturally find their affections and attentions being focused beyond themselves; animated with the desire to establish and perpetuate Zion, they come to dwell in righteousness, become of one heart and one mind, and see to the needs of those about them (see Moses 7:18).
“And it came to pass that the disciples whom Jesus had chosen began from that time forth to baptize and to teach as many as did come unto them; and as many as were baptized in the name of Jesus were filled with the Holy Ghost.
“And many of them saw and heard unspeakable things, which are not lawful to be written. And they taught, and did minister one to another; and they had all things common among them, every man dealing justly, one with another.
“And it came to pass that they did do all things even as Jesus had commanded them. And they who were baptized in the name of Jesus were called the church of Christ.”
(3 Nephi 26:17-21.)
