"Faith is so much more than mere belief or assent. Faith stretches us. It forces us to reach beyond our senses, and in that reaching we develop spiritual strength and greater trust in the Lord....
"I repeat: faith, therefore, is more than belief. Faith is an active force, not a passive condition. I suspect that one reason why we have to develop it here on earth is because of the expectations that will be placed on us when we are in the next sphere. I offer this only as personal opinion, but the Lord has promised that those who are faithful will inherit all that the Father has.
"In the eternities to come, will those who create worlds do so because they have learned the laws of physics that govern the universe, or will they work through the exercise of perfect faith, or a combination of both? How much reaching and stretching will it take? We don’t know, but when Jesus says that by faith we can move mountains, is he merely being figurative or is there something about the power of faith that we now only dimly perceive, but that we must learn while here on earth?"
