Doctrine and Covenants
Yeah, it's rather amazing to see what kind of spiritual "resume'" people think they can present to an omniscient God who knows all about us.
Example: Most Mormons give an average of 10%...but actually the Bible says we're mere stewards and that God owns 100%!
Therefore a Mormon (or Christian) who hasn't stewarded 90% to God or to His Glory is shortchanging Him. That's called failing to glorify God; which isn't exactly endorsed by Him.
I took some time once to start tabulating all the "laws" mentioned @ Lds.org...I couldn't even find a single article there that referenced all of the laws Lds leaders say their people have to follow.
If they can't even be comprehensively listed, they won't be comprehensively followed.
So actually D&C 18:46 condemns even the best of Mormons!
