Quote by Brigham Young
Let you be ever so true and faithful to your friends and never forsake them, never turn traitor to the Gospel which you have espoused, but live on in neglect of your duty, how do you know but I am teaching false doctrine? How do you know that I am not counseling you wrong? How do you know but I will lead you to destruction? And this is what I wish to urge upon you—live so that you can discern between truth and error, between light and darkness, between the things of God and those not of God, for by the revelations of the Lord, and these alone, can you and I understand the things of God.
