Much sifting will occur because of lapses in righteous behavior which go unrepented of. A few will give up instead of holding out to the end. A few will be deceived by defectors. Likewise, others will be offended, for sufficient unto each dispensation are the stumbling blocks thereof! A few will stumble because, in their preoccupation with the cares of the world, they do not have oil in their lamps. And, again and again, those who refuse to eat their spiritual spinach will come off second when they wrestle with the world. – Neal A. Maxwell, “Be of Good Cheer,” Ensign (CR) November 1982
