1 Nephi 1:1

1 Nephi 1:1  Nephi had many afflictions. Why did he consider himself highly favored of the Lord?

How can I feel "favored of the Lord" in the midst of my afflictions?

 Nephi continued that he "had a great knowledge of the goodness and the mysteries of God." In the Oct 2088 General Conference, Elder Bednar said,

"Revelation is communication from Heavenly Father to His children on earth. As we ask in faith, we can receive revelation upon revelation and knowledge upon knowledge and come to know the mysteries and peaceable things that bring joy and eternal life (see D&C 42:61). The mysteries are those matters that can only be known and understood by the power of the Holy Ghost (see Harold B. Lee, Ye Are the Light of the World [1974], 211)." [italics added]

 The mysteries of God are known via revelation through the Holy Ghost, which bears record of the Father and the Son. If Nephi had the companionship of the Holy Ghost (and he did), then he had access to gifts of the Spirit, which include peace and comfort, which he would have needed to pass through his afflictions.

Nephi kept a record of his life. What purpose does keeping a journal serve? To remember what has passed, revelations we have received, evidences of God's love and tender mercies in our lives, testimonies, a witness to those who may later read it, a warning, an example...

Of record keeping (personal journal), President Kimball said,

"Accordingly, we urge our young people to begin today to write and keep records of all the important things in their own lives...Your own private journal should record the way you face up to challenges that beset you. Do not suppose life changes so much that your experiences will not be interesting to your posterity. Experiences of work, relations with people, and an awareness of the rightness and wrongness of actions will always be relevant." "The Angels May Quote From It" also the BoM Student Manual

President Kimball also said that "remember" might be the most important word, "when you look in the dictionary for the most important word, do you know what it is?  It could be 'remember.' Because all of (us) have made covenants...our greatest need is to remember."
