Joseph Smith: A Prophet of God When Joseph Smith was 14 years old, he wanted to know which church he should join, so he asked God in sincere prayer. In response to this prayer, God the Father and His Son, Jesus Christ, appeared to Joseph and told him the true Church of Jesus Christ was not on the earth and they had chosen Joseph to restore it. From that day, Joseph labored in God's service, working to establish The Church of Jesus Christ of Latter-day Saints and to build up God's kingdom on earth in the latter days. Faithful members of the Church witness that Jesus Christ is the Savior and Redeemer of the world. Jesus directs His Church today through revelation to a prophet on the earth. Joseph Smith was such a prophet. Although Joseph accomplished many things during his life, most important was his commitment to being a disciple and witness of Jesus Christ. He wrote, "After the many testimonies which have been given of him, this is the testimony, last of all, which we give of him: That he lives!" (Doctrine and Covenants 76:22). Those who receive the Prophet's testimony by the power of the Holy Ghost will know the truth of the work he was called to do. They can also know the peace and happiness that come through the Savior Jesus Christ, whom Joseph Smith worshiped and served.
