The lesson was based on Elder Quentin L Cook's conference talk, Personal Peace: The Reward of Righteousness
There is a difference between world peace and personal peace.
We have a lot of control over personal peace, but less over world peace.
Personal peace is not dependent on world peace.
Agency makes peace possible.
2 Nephi 2:26
26 And the Messiah cometh in the fulness of time, that he may redeem the children of men from the fall. And because that they are redeemed from the fall they have become free forever, knowing good from evil; to act for themselves and not to be acted upon, save it be by the punishment of the law at the great and last day, according to the commandments which God hath given.
16 ¶ Behold, I send you forth as sheep in the midst of wolves: be ye therefore wise as serpents, and harmless as doves.
Doctrine and Covenants 1:35
35 For I am no respecter of persons, and will that all men shall know that the day speedily cometh; the hour is not yet, but is nigh at hand, when peace shall be taken from the earth, and the devil shall have power over his own dominion.
We must actively seek peace. Our personal peace is not dependant on the peace of the earth.
Forgiveness is a key to peace.
Doctrine and Covenants 64:10
10 I, the Lord, will forgive whom I will forgive, but of you it is required to forgive all men.
All men, including yourself.
Trials are often given when we need and have been prepared for growth.
"Peace is not found by attaining great wealth, power, or prominence.22 Peace is not found in the pursuit of pleasure, entertainment, or leisure. None of these can, even when attained in abundance, create any lasting happiness or peace." - Elder Cook
Lesson 28 - Doctrine and Covenants 121,122,123
Some of the Lesson was taken from Elder Jeffrey R Holland’s talk at a CES fireside reprinted in the September 2009 Ensign, Lessons from Liberty Jail,
The Doctrine and Covenants is real answers to real prayers by real people that really apply to us today.
The early saints of the latter-days came out of the trials understanding things they did not understand before. They knew things they didn't know before. They were prepared for things they were not prepared to deal with before.
19 Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:20 Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen.
