If you believe in Christ, then He has prescribed the steps needed to be taken in order to exhibit or prove your belief in Him. These are His words:
“[N]either shall there be disputations among you concerning the points of my doctrine, as there hath hitherto been. For verily, verily I say unto you, he that hath the spirit of contention is not of me, but is of the Devil, who is the father of contention; and he stirreth up the hearts of men to contend with anger, one with another. Behold, this is not my doctrine, to stir up the hearts of men with anger, one against another, but this is my doctrine, that such things should be done away.
Behold, verily, verily I say unto you, I will declare unto you my doctrine. And this is my doctrine, and it is the doctrine which the Father hath given unto me — and I bear record of the Father, and the Father beareth record of me, and the holy ghost beareth record of the Father and me — and I bear record that the Father commandeth all men everywhere to repent and believe in me. And whoso believeth in me, and is baptized, the same shall be saved, and they are they who shall inherit the kingdom of God. And whoso believeth not in me, and is not baptized, shall be damned.” (RE 3 Ne. 5:8-9)
He phrases this requirement first in the negative: Do not dispute over His doctrine, and avoid getting angry over religious differences.
Then He phrases it in the positive: If you believe then show it by being baptized. If you are baptized, you will be saved, and if not you will be damned.
Two words need to be understood: “Disputation” is wrong when men’s hearts are provoked to anger. In a modern revelation the Lord explained where this leads, and exactly how religious divisions have caused misery: “Mankind has been controlled by the adversary through anger and jealousy, which has led to bloodshed and the misery of many souls. Even strong disagreements should not provoke anger, nor to invoke my name in vain as if I had part in your every dispute.” (T&C 157:54)
Throughout “Christian” history, religious warfare has happened continually. Even today there continues to be violence over religious differences. The Lord commands that to end.
The word “damned” has been defined in the new scriptures Glossary of Terms: “To cease progressing or to regress. Damnation merely means the end of progress. So when one fails to progress in understanding, he voluntarily damns himself. ‘When God offers a blessing or knowledge to a man, and he refuses to receive it, he will be damned. If mankind is to be saved, it will be through their acquisition of knowledge. Put otherwise, it is stupidity that damns them; it is knowledge which saves man. Damnation means hedging up the way so that one cannot progress.” (T&C Glossary, Damned)
Baptism is required for progress in this and the afterlife. As the New Covenants puts it: “And now, if the Lamb of God, he being holy, should have need to be baptized by water to fulfill all righteousness, Oh, then, how much more need have we, being unholy, to be baptized, yea, even by water?” (2 Ne. 13:2)
As Christ put it before His own baptism, after John said Christ was more worthy than himself: “Suffer me to be baptized of you, for thus it becomes us to fulfill all righteousness.” (Matt. 2:4) Christ provided the example of the path He expects us to follow. His example included being baptized. If you believe in Him, then you too must be baptized.
