Mormon 9:21-25

Moroni tells us the charge to the three Nephites was to preach the gospel to the world. This charge has been a part of the true gospel. Missionary work was the last recorded charge Christ gave his apostles in the Gospel of Matthew.

“Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:

“Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen” (Matthew 28:19-20).

During His ministry, Christ sent the seventy to preach His gospel. “After these things the Lord appointed other seventy also, and sent them two and two before his face into every city and place, whither he himself would come” (Luke 10:1).

Obedience to missionary work continued after Christ’s departure. “And he commanded us to preach unto the people, and to testify that it is he which was ordained of God to be the Judge of quick and dead” (Acts 10:42).

The charge continues in this dispensation. “And now, behold, I say unto you, that the thing which will be of the most worth unto you will be to declare repentance unto this people, that you may bring souls unto me, that you may rest with them in the kingdom of my Father. Amen” (D&C 15:6).

“Wherefore, you are called to cry repentance unto this people.

“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!” (D&C 18:14-15).

“Again I say, hearken ye elders of my church, whom I have appointed: Ye are not sent forth to be taught, but to teach the children of men the things which I have put into your hands by the power of my Spirit” (D&C 43:15).

The believer who is baptized will be saved. Those who reject the gospel will be damned.

“And he said unto them in his doctrine, Beware of the scribes, which love to go in long clothing, and love salutations in the marketplaces,

“And the chief seats in the synagogues, and the uppermost rooms at feasts:

“Which devour widows’ houses, and for a pretence make long prayers: these shall receive greater damnation” (Mark 12:38-40).

“That they all might be damned who believed not the truth, but had pleasure in unrighteousness” (2 Thessalonians 2:12).

“And if they will not repent and believe in his name, and be baptized in his name, and endure to the end, they must be damned; for the Lord God, the Holy One of Israel, has spoken it” (2 Nephi 9:24).

Signs will follow those which believe. “But, behold, faith cometh not by signs, but signs follow those that believe” (D&C 69:3). In His name, the righteous shall cast out devils, speak with new tongues, they will bless the sick and they will recover. “And it shall come to pass that he that feareth me shall be looking forth for the great day of the Lord to come, even for the signs of the coming of the Son of Man” (D&C 45:39).

Whomever will believe in His name, with no doubt, will receive His confirmation of all His words. “The law of the Lord is perfect, converting the soul: the testimony of the Lord is sure, making wise the simple” (Psalms 19:7).

“He saith unto them, But whom say ye that I am [The plural noun used here in the Greek indicates that Jesus asked this question of the apostles and not just one of them]?

“And Simon Peter answered and said, Thou art the Christ, the Son of the living God.

“And Jesus answered and said unto him, Blessed art thou, Simon Bar-jona [IE son of Jonah]: for flesh and blood hath not revealed it unto thee, but my Father which is in heaven” (Mathew 16:15-17).

“And it came to pass that he said unto them: Behold, here are the waters of Mormon (for thus were they called) and now, as ye are desirous to come into the fold of God, and to be called his people, and are willing to bear one another’s burdens, that they may be light;

“Yea, and are willing to mourn with those that mourn; yea, and comfort those that stand in need of comfort, and to stand as witnesses of God at all times and in all things, and in all places that ye may be in, even until death, that ye may be redeemed of God, and be numbered with those of the first resurrection, that ye may have eternal life” (Mosiah 18:8-9).
