Joseph F. Smith said on September 3, 1892,
Concerning the question of blind obedience. Not a man in this Church, since the Prophet Joseph Smith down to the present day, has ever asked any man to do as he was told blindly. No Prophet of God, no Apostle, no President of a Stake, no Bishop, who has had the spirit of his office and calling resting upon him, has ever asked a soul to do anything that they might not know was right and the proper thing to do. We do not ask you to do anything that you may not know it is your duty to do, or that you may not know will be a blessing for you to do.
If we give you counsel, we do not ask you to obey that counsel without you know that it is right to do so. But how shall we know that it is right? By getting the Spirit of God in our hearts, by which our minds may be opened and enlightened, that we may know the doctrine for ourselves, and be able to divide truth from error, light from darkness and good from evil.
