God himself, finding he was in the midst of spirits and glory, because he was more intelligent, saw proper to institute laws whereby the rest could have a privilege to advance like himself. The relationship we have with God places us in a situation to advance in knowledge. He has power to institute laws to instruct the weaker intelligences, that they may be exalted with Himself, so that they might have one glory upon another, and all that knowledge, power, glory, and intelligence, which is requisite in order to save them in the world of spirits. (King Follett Discourse)
Joseph Smith, Jr.It is vain to try and hide a bad spirit from the eyes of them who are spiritual, for it will show itself in speaking and in writing as well as in all other conduct, it is also useless to make great pretensions when the heart is not right before God, for God looks at the heart, and where the heart is not right the Lord will expose it to the view of the faithful.
Joseph Smith, Jr.Let us this very day begin anew, and now say, with all our hearts, we will forsake our sins and be righteous.
Joseph Smith, Jr.Therefore, dearly beloved brethren, let us cheerfully do all things that lie in our power; and then may we stand still, with the utmost assurance, to see the salvation of God, and for his arm to be revealed.
Joseph Smith, Jr.
