Joseph Smith - Baptism and the Gift of the Holy Ghost

After the Prophet Joseph Smith went to Washington D.C. -

"...to seek redress for the wrongs done to the Missouri Saints, Joseph Smith and Elias Higbee wrote the following to Hyrum Smith: “In our interview with the President [of the United States], he interrogated us wherein we differed in our religion from the other religions of the day. Brother Joseph said we differed in mode of baptism, and the gift of the Holy Ghost by the laying on of hands. We considered that all other considerations were contained in the gift of the Holy Ghost.”

The Prophet explained of the other considerations -

"We believe in the gift of the Holy Ghost being enjoyed now, as much as it was in the Apostles’ days; we believe that it [the gift of the Holy Ghost] is necessary to make and to organize the Priesthood, that no man can be called to fill any office in the ministry without it; we also believe in prophecy, in tongues, in visions, and in revelations, in gifts, and in healings; and that these things cannot be enjoyed without the gift of the Holy Ghost..."

"We believe that the holy men of old spake as they were moved by the Holy Ghost, and that holy men in these days speak by the same principle..."

"We believe in its being a comforter and a witness bearer, that it brings things past to our remembrance, leads us into all truth, and shows us of things to come; we believe that 'no man can know that Jesus is the Christ, but by the Holy Ghost'..."

In February 1847, nearly three years after the Prophet Joseph Smith was martyred, he appeared to President Brigham Young and said -

“Tell the people to be humble and faithful and sure to keep the Spirit of the Lord and it will lead them right. Be careful and not turn away the small still voice; it will teach [you what] to do and where to go; it will yield the fruits of the kingdom. Tell the brethren to keep their hearts open to conviction so that when the Holy Ghost comes to them, their hearts will be ready to receive it. They can tell the Spirit of the Lord from all other spirits. It will whisper peace and joy to their souls, and it will take malice, hatred, envying, strife, and all evil from their hearts; and their whole desire will be to do good, bring forth righteousness, and build up the kingdom of God. Tell the brethren if they will follow the Spirit of the Lord they will go right.”

The difference between the Church of Jesus Christ of Latter-day Saints and all other organizations is this consideration - the priesthood has been restored with power to give the Gift of the Holy Ghost. The difference then is that this Church possesses the Gift of the Holy Ghost.l
