6 We believe in the same organization that existed in the Primitive Church, namely, apostles, prophets, pastors, teachers, evangelists, and so forth.
Throughout the Bible we read about prophets and apostles through whom God worked to carry out His will. A few of the prophets mentioned in the Bible are Moses, Abraham, Isaiah, Jeremiah, and Elijah.
In Amos 3:7 we read, " 7 Surely the Lord God will do nothing, but he revealeth his secret unto his servants the prophets.". This is the pattern that God has followed throughout time. When Jesus was on the Earth, He set up the organization of His church with apostles and prophets. In these latter days, this same organization was restored to the earth through the prophet Joseph Smith. Today, the Church of Jesus Christ of Latter-Day Saints has a Prophet and Apostles that carry out God's will on the Earth.
In the LDS guide to the scriptures we read that a prophet is: "A person who has been called by and speaks for God. As a messenger of God, a prophet receives commandments, prophecies, and revelations from God. His responsibility is to make known God’s will and true character to mankind and to show the meaning of his dealings with them. A prophet denounces sin and foretells its consequences. He is a preacher of righteousness. On occasion, prophets may be inspired to foretell the future for the benefit of mankind. His primary responsibility, however, is to bear witness of Christ. The President of The Church of Jesus Christ of Latter-day Saints is God’s prophet on earth today. Members of the First Presidency and the Twelve Apostles are sustained as prophets, seers, and revelators."
