Why did the Lord inspire Mormon (or Moroni or Alma) to include that in his record? What lesson can I learn from that to help me live in this day and age?

When you choose to follow Christ, you choose to be changed. Men and women changed for Christ will be captained by Christ. Their will is swallowed up in His will. They do always those things that please the Lord. Not only would they die for the Lord, but more important they want to live for Him. They stand as witnesses of God at all times, and in all things, and in all places. They have Christ on their minds, as they look unto Him in every thought. They have Christ in their hearts as their affections are placed on Him forever.

It is not enough simply to try to resist evil or empty our lives of sin. We must also fill our lives with righteousness

One of Satan's most frequently used deceptions is the notion that the commandments of God are meant to restrict freedom and limit happiness.

If we are to achieve long-range goals, we must learn to set up and accomplish short-range goals that will move us along the way. If we do not consciously select our goals, we may be controlled by goals not of our own choosing - goals imposed by outside pressures (such as the expectations of others) or by our habits (such as procrastination) or by our desire for the approval of the world.

The Book of Mormon is also the keystone of the doctrine of the Resurrection. As mentioned before, the Lord Himself has stated that the Book of Mormon contains the "fulness of the gospel of Jesus Christ".

As members of the Lord's Church, we must take missionary work more seriously. The Lord's commission to 'preach the gospel to every creature' (Mark 16:15) will never change in our dispensation. We have been greatly blessed with the material means, the technology, and an inspired message to bring the gospel to all men. More is expected of us than any previous generation. Where 'much is given much is required.' (D&C 82:3.)
