Joseph Smith, Jr. and Sidney Rigdon

“ Would it not be that it was the assurance which we had of the existence of things which we had not seen, as yet?— Was it not the hope which you had, in consequence of your belief in the existence of unseen things, which stimulated you to action and exertion, in order to obtain them? Are you not dependent on your faith, or belief, for the acquisition of all knowledge, wisdom and intelligence? Would you exert yourselves to obtain wisdom and intelligence, unless you did believe that you could obtain them? ”

“ Take this principle or attribute, (for it is an attribute) from the Deity and he would cease to exist.
17 Who cannot see, that if God framed the worlds by faith, that it is by faith that he exercises power over them, and that faith is the principle of power? And that if the principle of power, it must be so in man as well as in the Deity? This is the testimony of all the sacred writers, and the lesson which they have been endeavoring to teach to man. ”

“ A. By it they exist, by it they are upheld, by it they are changed, or by it they remain, agreeably to the will of God; and without it there is no power; and without power there could be no creation, nor existence! ”
