Alma Chapter 55

55:23 - "...and thus they saw that the Nephites had power over them; and in these circumstances they found that it was not expedient that they should fight with the Nephites..."
Not expedient...?  No kidding - you're surrounded!  The Lamanites recognized that they would not win, so they delivered up their weapons of war, asking for mercy.
Sometimes we need to realize that our situation makes it unwise to continue in our activity.  We need to realize when it is "not expedient" to continue.  Perhaps at that time we're trying to run faster than we have strength.  We must be careful to have the Spirit with us at all times so we can avoid those situations.

55:31 - "...but behold, the Nephites were not slow to remember the Lord their God in this their time of affliction. They could not be taken in their snares; yea, they would not partake of their wine, save they had first given to some of the Lamanite prisoners..."
If the wine would poison a Lamanite, it would also poison a Nephite.  We need to keep this in mind as we look at movies, music, media, an other similar situations.  If it will poison a kid, it can also poison an adult.
We need to put ourselves and our homes into situations where we will not be poisoned.


55:31-32 - "...but behold, the Nephites were not slow to remember the Lord their God in this their time of affliction..."
When we have faith in the Lord and are not slow to remember Him, then we will have the help we need to recognize and avoid temptation.
