I delight in rest.

It is through the healing Atonement of Jesus Christ that we may have the strength to stand tall and strong and to have our souls be filled—with light, understanding, joy, and love. His invitation is extended to “all to come unto him and partake of his goodness; and he denieth none that come unto him” (2 Nephi 26:33). His promise is:

“Come unto me, all ye that labour and are heavy laden, and I will give you rest.

“Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls” (Matthew 11:28–29).

Of this rest President Joseph F. Smith said:

To my mind, it means entering into the knowledge and love of God, having faith in his purpose and in his plan, to such an extent that we know we are right, and that we are not hunting for something else, we are not disturbed by every wind of doctrine, or by the cunning and craftiness of men who lie in wait to deceive. We know of the doctrine that it is of God, and we do not ask any questions of anybody about it; they are welcome to their opinions, to their ideas and to their vagaries. The man who has reached that degree of faith in God that all doubt and fear have been cast from him, he has entered into ‘God’s rest’

(Teachings of Presidents of the Church: Joseph F. Smith [1998], 56).
