Brigham Young,
Journal of Discourses — Volume 10…
“ Let us from this time strive more diligently to overcome our own evil passions. We may talk about Priesthood, about power and authority, about blessings and exaltations, about the kingdom of God upon the earth, about gathering the house of Israel, about redeeming Zion and enjoying its fulness, about preparing for the coming of the Son of Man and enjoying celestial glory with him, but all this is vain if we do not sanctify ourselves before God, and sanctify the Lord our God in our hearts. ”
