You hearken to that still small voice that whispers eternal truth, that opens the visions of eternity to you that you can discern, understand and follow, and the foul spirits that throng the air, and that fill our houses if we let them in, will not have power over you. 15:7.
Every individual that lives according to the laws that the Lord has given to his people, and has received the blessings that he has in store for the faithful, should be able to know the things of God from the things which are not of God, the light from the darkness, that which comes from heaven and that which comes from somewhere else. This is the satisfaction and the consolation that the Latter-day Saints enjoy by living their religion; this is the knowledge which every one who thus lives possesses. 16:163.
Now, I ask the wise, where did you get your wisdom? Was it taught you? Yes, I say it was taught you. By your professors in college? No, it was taught you by the influence of the spirit that is in man, and the inspiration of the Spirit of God giveth it understanding; and every creature can thus add intelligence to intelligence. 13:172.
Revelation—No person can receive a knowledge of this work, except by the power of revelation. 8:315.
The spirit of revelation, even the spirit of eternal life, is within that person who lives so as to bear properly the yoke of Jesus. The heavens are open to such persons, and they see and understand things that pertain to eternity, and also the things that pertain to this earth. 8:206.
The spirit of revelation attends the Gospel, and without that spirit no man can understand it. 8:130.
Many of the first revelations given to Joseph were of a temporal character, pertaining to a literal kingdom on the earth. And most of the revelations he received in the early part of his ministry pertained to what the few around him should do in this or in that case—when and how they should perform their duties; at the same time calling upon them to preach the Gospel and diffuse the spirit and principles of the Kingdom of God, that their eyes might be open to see and gather the people together that they might begin and organize a literal, temporal organization on the earth. 6:171.
How can you know the Latter-day work to be true? You can know it only by the spirit of revelation direct from heaven.
What proved this work true to you in England, Ireland, Scotland, Germany, France, the United States, etc.? Was it not the spirit of revelation that rested upon you? Then why should you lose the spirit? You should add to it day by day; you should add as the Lord gives—a little here and a little there, and treasure up truth in your faith and understanding, until you become perfect before the Lord and are prepared to receive the further things of the Kingdom of God. 7:159-160.
This principle we are in possession of, and it should be nourished and cherished by us; it is the principle of revelation, or, if you like the term better, of foreseeing. There are those who possess fore-knowledge, who do not believe as we believe with regard to the establishment of the Kingdom of God on the earth. Take the statesman, for instance: he has a certain degree of knowledge with regard to the results of the measures which he may recommend, but does he know whence he derived that knowledge? No. He may say: "I foresee if we take this course we shall perpetuate our government and strengthen it, but if we take the opposite course we will destroy it." But can he tell whence he has received that wisdom and fore-knowledge? He cannot. Yet that is the condition of the statesmen in the nations of the earth. If the philosopher can gaze into the immensity of space, and understand how to fashion and make glasses that will magnify a million times, that knowledge comes from the Fountain of knowledge. A man of the world may say: "I can foresee, I can understand, I can frame an engine, make a track, and run that engine upon it, bearing along a train of loaded cars at the rate of forty, fifty, or sixty miles an hour." Another may say: "I can take the lightning, convey it on wires, and speak to foreign nations." But where do they get this wisdom? From the same source where you and I get our wisdom and our knowledge of God and godliness. 12:112-13.
