And this counsel seems pointed.We take the sacred writings into our hands, and admit that they were given by direct inspiration for the good of man. We believe that God condescended to speak from the heavens and declare His will concerning the human family, to give them just and holy laws, to regulate their conduct, and guide them in a direct way, that in due time He might take them to Himself, and make them joint heirs with His Son. But when this fact is admitted, that the immediate will of heaven is contained in the Scriptures, are we not bound as rational creatures to live in accordance to all its precepts? Will the mere admission, that this is the will of heaven ever benefit us if we do not comply with all its teachings? Do we not offer violence to the Supreme Intelligence of heaven, when we admit the truth of its teachings, and do not obey them? Do we not descend below our own knowledge, and the better wisdom which heaven has endowed us with, by such a course of conduct? For these reasons, if we have direct revelations given us from heaven, surely those revelations were never given to be trifled with, without the trifler's incurring displeasure and vengeance upon his own head, if there is any justice in heaven; and that there is must be admitted by every individual who admits the truth and force of God's teachings, His blessings and cursings, as contained in the sacred volume. - Joseph Smith
Mosiah 23:14 And also trust no one to be your teacher nor your minister, except he be a man of God, walking in his ways and keeping his commandments.
