Something this VITAL should be available withOUT having to 'look hard'.
EVERY doctrine 'needed' for salvation is found with the pages of the Bible, so just WHY should someone look elsewhere?
It was right in plan sight. If you would have read those things you would have seen a wonderful biblical history of temples. But, just like so many others, your purpose is not to find out what people believe but to try and find things so you can proove them “wrong”.
You ask why someone should look elsewhere. Because the common people in the time of Christ and after never even had the scriptures let alone the complete Bible. Which was more important to them, the scripturs or the Apostle Paul? The Lord has given additional instruction today. Read with the right attitude and you will see! www.lds.org
