Continuing Revelation and Scripture

My LDS friend had a gospel conversation with a colleague at work and gave an excellent analogy about the importance of continuing revelation.

My LDS friend was talking about the Book of Mormon to his work colleague.  The work colleague responded "everything that God wants us to know is in the Bible and the Bible is all I need".

My LDS friend then said, "imagine you taught your child everything they needed to know before they were 8 years old and  then after that you never taught them anything else.  How do you think your child would turn out?  Don't you think your child would need continual guidance?" 

In the same way a young child still needs direction and guidance from his parents, Our Heavenly Father continues to give us guidance and direction to His Church through Prophets and Apostles, continuing revelation and scripture.
