"But here we lay the foundation. Here is where we are taught these simple truths of the Gospel of Jesus Christ, in this probationary state, to prepare us for that perfection. It is my duty, it is yours, to be better today than I was yesterday, and for you to be better today than you were yesterday, and better tomorrow than you were today. Why? Because we are on that road, if we are keeping the commandments of the Lord, we are on that road to perfection, and that can only come through obedience and the desire in our hearts to overcome the world” (Teachings of Presidents of the Church: Joseph Fielding Smith, p. 234-235).
