“He had begun to associate with the wrong kinds of people; he eventually surrendered to the allurements and pressures to conform to the ways of the worldly. But, Alma scolded, because others gave in to sin was no reason for him to do the same: This was no excuse for thee, my son. Thou shouldst have tended to the ministry where with thou wast entrusted (Alma 39:3-4).” (Robert Millet, Studies in Scripture, ed. by K. Jackson, 8:49)
“Oh, if our young people could learn this basic lesson to always keep good company, never to be found with those who tend to lower their standards! Let every youth select associates who will keep him on tiptoe, trying to reach the heights. Let him never choose associates who encourage him to relax in carelessness.” (Teachings of Spencer W. Kimball, p. 287)
“Genuine friends often can provide spiritual shepherding. Note that I refer to genuine friends in the category of spiritual shepherds. Notice also that I did not include peers in that group. I readily acknowledge that peers in some cases can be and are an influence for good… . Unfortunately, so many times there are situations where peer influence has a definite negative effect. We read and hear of so many surveys and interviews where youth disclose that it was the influence and pressure of peers that led them to immoral and foolish behavior. Satan knows this… . He is aware of the tremendous influence a group of peers can have on an individual. There is a compelling desire to belong—to be one of the group… . Often the easiest and simplest nudging is that ‘everyone is doing it’ or ‘it’s the cool thing’ or ‘how do you know it’s bad if you haven’t tried it?’ Don’t be deceived. Don’t be influenced with this kind of enticement. Keep your eyes above the crowd.” (W. Eugene Hansen, Ensign, May 1996, pp. 38-39)
“We know that we are often judged by the company we keep. We know how influential classmates, friends, and other peer groups can be. If any of our companions are prone to be unrighteous in their living, we are better off seeking new associations immediately. Our friends should be companions who inspire us, who help us rise to our best.” (Joseph B. Wirthlin, Ensign, Nov. 1997, p. 34)
