The first post - Doctrine and Covenants

I'm taking a class on the Doctrine and Covenants this year. I believe that the Doctrine and Covenants is a book of scripture given to the world by Jesus Christ through Joseph Smith. I believe this because I feel inside me that it's right.
I'm a member of the Church of Jesus Christ of Latter-day Saints, better known by most people as the Mormon Church, though that's just a nickname. We believe that the Doctrine and Covenants is canonized scripture along with the Bible (both New and Old Testaments) and the Book of Mormon.
The Book of Mormon was also given to the world through Joseph Smith, but is very different from the Doctrine and Covenants. The Book of Mormon is a book of scripture written by people that lived in the ancient Americas. They wrote some of their history and a lot about Jesus Christ. Just like in the Bible, when we read the Book of Mormon we can learn lessons from people who lived before us and apply them to our own lives.
The Doctrine and Covenants is a book of revelations received by Joseph Smith for the present time. It applies directly to us today.
The reason why we believe it's scripture is because we believe that Joseph Smith was called to be a prophet by God and Jesus Christ. So, it's like in Biblical times. Moses was called to be a prophet, so we accept his writings as the word of God, Isaiah was called to be a prophet, so we accept his writings to be the word of God, etc. In just the same way we accept Joseph Smith's writings as the word of God because we believe that he was a prophet.

So, because I really believe in this I'm excited for the class and learning more about it.
