D&C 117

 The Lord gave an eternal perspective to Newel K. Whitney - 

"Let them repent of all their sins, and of all their covetous desires, before me, saith the Lord; for what is property unto me? saith the Lord."  (Doctrine and Covenants 117:4)

In my mind, this falls under the law of sacrifice...things that we possess

Again, from an eternal perspective - 

"Is there not room enough on the mountains of Adam-ondi-Ahman, and on the plains of Olaha Shinehah, or the land where Adam dwelt, that you should covet that which is but the drop, and neglect the more weighty matters?"  (Doctrine and Covenants 117:8)
