I know Joseph Smith was a Prophet of God

I know Joseph Smith was a true prophet. First, he was visited by God, our Father and Jesus Christ. Later, he was visited by the angel Moroni and given golden plates to translate that are now known as the Book of Mormon. Joseph Smith translated these plates by the power of God. Joseph Smith was also visited by Peter, James and John and given the very priesthood that Christ himself gave to them. Joseph Smith reestablished Christ's church on the earth in this time. He was truly a chosen prophet of God.
