Perfection Doesn’t Come All At Once

“Do not expect to become perfect at once. If you do, you will be disappointed. Be better today than you were yesterday, and be better tomorrow than you are today. The temptations that perhaps partially overcome us today, let them not overcome us so far tomorrow. Thus continue to be a little better day by day; and do not let your life wear away without accomplishing good to others as well as to ourselves” (Teachings of Presidents of the Church: Lorenzo Snow[2012], 103).
Perfection Is Like Climbing a Ladder

“It is not wisdom that we should have all knowledge at once presented before us; but that we should have a little at a time; then we can comprehend it”
Teachings of Presidents of the CHurch: Joseph Smith [2007] p 268

“When you climb up a ladder, you must begin at the bottom, and ascend step by step, until you arrive at the top; and so it is with the principles of the gospel—you must begin with the first, and go on until you learn all the principles of exaltation. But it will be a great while after you have passed through the veil before you will have learned them. It is not all to be comprehended in this world; it will be a great work to learn our salvation and exaltation even beyond the grave” (Teachings of Presidents of the Church: Joseph Smith [2007], 268).
