I found the following quote by Brigham Young concerning the eternal principle of work:
"We will have to go to work and get the gold out of the mountains to lay down, if we ever walk in streets paved with gold. The angels that now walk in their golden streets … had to obtain that gold and put it there. When we have streets paved with gold, we will have placed it there ourselves. When we enjoy a Zion in its beauty and glory [which we’re looking forward to], it will be when we have built it. ..."
Wait a minute! There will be road construction in heaven?! This I would not have supposed. (But, that explains a lot about Utah and its extensive, never ending construction on every road or freeway you want to use, including your "back way". It's closer to heaven than I thought.)
