I counsel you to stop and think what you are doing, before you commit any more sins, before you give way to your temper. The temper, or the evil propensities of men, when given way to, are the cause of their sinning so much. The Lord is suffering the devil to work upon and try His people. The selfish will, operated upon by the power of Satan, is the strongest cord that vibrates through the human system. This has been verified a thousand times. Men have sacrificed their money, their health, their good names, their friends, and have broken through every tender tie to gratify their wills. Curb that, bridle the tongue, and then hold the mastery over your feelings, that they submit not to the will of the flesh, but to the will of the Holy Ghost; and decide in your own minds that your will and judgment shall be none other than the will and judgment of the Spirit of God, and you will then go and sin no more.
Brigham Young, October 23, 1853, Journal of Discourses 2:9
