"Man may deceive his fellow men, deception may follow deception, and the children of the wicked one may have power to seduce the foolish and untaught; till naught but fiction feeds the many, and the fruit of falsehood carries in its current the giddy to the grave."
― Joseph Smith Jr.

"A man is saved no faster than he gets knowledge, for if he does not get knowledge, he will be brought into captivity by some evil power in the other world, as evil spirits will have more knowledge, and consequently more power than many men who are on the earth. Hence it needs revelation to assist us, and give us knowledge of the things of God."
― Joseph Smith Jr., Teachings of the Prophet Joseph Smith

"And if the question is asked, how were they to obtain the knowledge of God? (for there is a great difference between believing in God and knowing him -- knowledge implies more than faith. And notice, that all things that pertain to life and godliness were given through the knowledge of God) the answer is given -- through faith they were to obtain this knowledge; and, having power by faith to obtain the knowledge of God, they could with it obtain all other things which pertain to life and godliness."
― Joseph Smith Jr., Lectures on Faith

"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.

"The best way to obtain truth and wisdom is not to ask from books, but to go to God in prayer, and obtain divine teaching."
― Joseph Smith Jr.

"A person may profit by noticing the first intimation of the spirit of revelation; for instance, when you feel pure intelligence flowing into you, it may give you sudden strokes of ideas, so that by noticing it, you may find it fulfilled the same day or soon; (i.e.) those things that were presented unto your minds by the Spirit of God, will come to pass; and thus by learning the Spirit of God and understanding it, you may grow into the principle of revelation, until you become perfect in Christ Jesus."
― Joseph Smith

"For he that diligently seeketh shall find; and the mysteries of God shall be unfolded unto them, by the power of the Holy Ghost, as well in these times as in times of old, and as well in times of old as in times to come; wherefore, the course of the Lord is one eternal round."
― Joseph Smith Jr., The Book of Mormon

"The things of God are of deep import and time and experience and careful and ponderous and solemn thoughts can only find them out. Thy mind O man if thou wilt lead a soul into salvation must search into and contemplate the darkest abyss and the broad expanse of eternity, thou must commune with God." (Joseph Smith, History of the Church, vol. 3, p. 295.)
