I think the greatest advancement comes when we are willing to share everything we have with everyone else. This would be a far greater achievement than any flashy or comfort-producing technology. I believe that our Heavenly Father wants to give us so much more than we currently have, however, there are eternal laws that must be in operation if we are to receive any blessings from heaven. As we come to understand the laws of physics better, we gain the greatest benefit by subjecting ourselves to these laws, and by incorporating these physical laws into our daily lives via machines and other helpful technologies. The same is true with eternal and heavenly laws. If we subject ourselves to correct spiritual laws, we will gain the greatest advantage, not only in this life, but also throughout all of our eternal existence.
