If you have the Holy Ghost, then you you have been baptized with fire and received a remission of sins because the Holy Ghost does not dwell in unclean temples and will not dwell in those who have not been baptized by fire and received a remission of sins.
If you want to experience the baptism of fire (remission of your sins as if by fire) and the gift of the Holy Ghost, here is what to do...
The words are NOT important, it is the feeling and intent. You can't act you way through it. You must really feel it.2 And they had viewed themselves in their own carnal state, even less than the dust of the earth. And they all cried aloud with one voice, saying: O have mercy, and apply the atoning blood of Christ that we may receive forgiveness of our sins, and our hearts may be purified; for we believe in Jesus Christ, the Son of God, who created heaven and earth, and all things; who shall come down among the children of men.
3 And it came to pass that after they had spoken these words the Spirit of the Lord came upon them, and they were filled with joy, having received a remission of their sins, and having peace of conscience, because of the exceeding faith which they had in Jesus Christ who should come, according to the words which king Benjamin had spoken unto them. - Mosiah 4
It is important to have a correct understanding of who God is. God is NOT the tyrant of the universe or the dictator of the universe. He does not smite us for not obeying him, but we are subject to the natural consequences of our actions which can be harmful and painful. He gives us commandments that will help us to avoid the undesirable natural consequences and gain the desirable natural consequences. He gives these commandments and we obey for our benefit, not His.
If you want to always retain a remission of your sins so that you can have the holy ghost as your constant companion...6 I say unto you, if ye have come to a knowledge of the goodness of God, and his matchless power, and his wisdom, and his patience, and his long-suffering towards the children of men; and also, the atonement which has been prepared from the foundation of the world, that thereby salvation might come to him that should put his trust in the Lord, and should be diligent in keeping his commandments, and continue in the faith even unto the end of his life, I mean the life of the mortal body—
7 I say, that this is the man who receiveth salvation, through the atonement which was prepared from the foundation of the world for all mankind, which ever were since the fall of Adam, or who are, or who ever shall be, even unto the end of the world. - Mosiah 4
This is wise advice from an angel who taught King Benjamin.11 And again I say unto you as I have said before, that as ye have come to the knowledge of the glory of God, or if ye have known of his goodness and have tasted of his love, and have received a remission of your sins, which causeth such exceedingly great joy in your souls, even so I would that ye should remember, and always retain in remembrance, the greatness of God, and your own nothingness, and his goodness and long-suffering towards you, unworthy creatures, and humble yourselves even in the depths of humility, calling on the name of the Lord daily, and standing steadfastly in the faith of that which is to come, which was spoken by the mouth of the angel.
12 And behold, I say unto you that if ye do this ye shall always rejoice, and be filled with the love of God, and always retain a remission of your sins; and ye shall grow in the knowledge of the glory of him that created you, or in the knowledge of that which is just and true. - Mosiah 4
