"Which is to show unto the remnant of the house of Israel what great things the Lord hath done for their fathers and that they may know the covenants of the Lord, that they are not cast off forever-And also to the convincing of the Jew and Gentile that JESUS is the CHRIST the ETERNAL GOD, manifesting himself unto all nations- And now if there are faults they are the mistakes of men"
- The Book of Mormon
The Book of Mormon is not a history book. The purpose of the Book of Mormon is stated in the above quote taken from the first page. "This is a book which needs to be read with a spirit of prayer and meditation." ( Elder Enrique R. Falabella). Read it then pray about the truthfulness and see what you receive for your answer. Horses, and steel, and elephants cannot explain away the fact the Book of Mormon presents the gospel in a way that plain, easy to understand, inspired, and most of all beautiful. Some things I have to exercise faith about, but I have never had a question about the truthfulness of this book.
When investigating the church I found it best to not believe everything I read on the internet or heard from family and friends that were reading negative media about The Church of Jesus Christ of Latter-Day Saints. I found it best to investigate the doctrine of the church and see if I found it to be the truth. Doctrine is not found in something a general authority said 100 years ago when he was speaking at a stake conference. Doctrine is found in the scriptures and the teachings of all the prophets and apostles. I hope this helps.
