My brothers and sisters, let us live true to the trust the Lord has placed in us. Let us strive for personal, practical integrity in every endeavor, regardless of how mundane or inconsequential it may seem. The small matters accumulate to shape the direction of our lives.
Elder Joseph B. Wirthlin, "Personal Integrity", General Conference, April 1990
Integrity! It's a word that is becoming obsolete. It's a characteristic that is becoming irrelevant.
It is imperative that we hold on to personal integrity. Let us choose good despite the fact that nobody is watching. Let us be faithful to what the Lord teaches. Let us be the "good Samaritan" and do likewise as told in the Bible. Let us be honest in all we do and when we interact with our fellow man. Afterall, we never do anything without someone watching, whether somebody watches on this side or on the other side of the veil.
We all have the capacity to know good from evil. Let us choose the good because every little, minor choice we make determines the direction we go and the destination at which we end up. And any little variation in direction we make now means a huge gap in where we end up. For example, flying from Los Angeles to New York, if the pilot veered to the right or to the left just a couple degrees, then that plane would end up hundreds of miles from New York in the end.
