When a servant of the Lord preaches the truth, he does a wonderful thing. When he does it with power and authority from God, and by the spirit, then his power to confound is increased, he speaks as a mouthpiece for the Lord, and his words are scripture: ’they shall speak as they are moved upon by the Holy Ghost. And whatsoever they shall speak when moved upon by the Holy Ghost shall be scripture, shall be the will of the Lord, shall be the mind of the Lord, shall be the word of the Lord, shall be the voice of the Lord, and the power of God unto salvation. Behold, this is the promise of the Lord unto you, O ye my servants’ (DC 68:3-5). This promise was given to the disciples of Christ’s day (Matt 10:19-20) and to his servants of the last days, ’lift up your voices unto this people; speak the thoughts that I shall put into your hearts, and you shall not be confounded before men; for it shall be given you in the very hour, yea, in the very moment, what ye shall say’ (DC 100:5-6).
Helaman 5:30 they heard this voice…of perfect mildness, as if it had been a whisper
The voice is heard three times but it is not the voice of an angel nor is it that ‘still small voice’ of the Holy Ghost. The voice heard was that of Jehovah. Remarkably, there is a perfect mildness and gentleness to his voice in spite of the fact that he is calling the people to repentance. This is the pattern he has established for us, ’And let your preaching be the warning voice, every man to his neighbor, in mildness and in meekness’ (DC 38:41).
However, his voice is not always perfectly mild as if a whisper. Before he appeared to the Nephites, a voice of doom was heard from the heavens (3 Nephi 9). At the dedication of the Kirtland temple, the Savior appeared and when he spoke, ’his voice was as the sound of the rushing of great waters, even the voice of Jehovah’ (DC 110:3). When He returns again, his voice will be ’as the voice of many waters, and as the voice of a great thunder’ (DC 133:22). But the voice of judgment had not yet come upon the Lamanites in this prison. There was time for them to repent, and the warning voice of the Lord was appropriately mild and gentle.
