"It is almost impossible to entirely avoid exposure to their products. You see these materials on all sides. But you need not fear if you have the slingshot of truth in your hands. You have been counseled and taught and advised. You have the stones of virtue and honor and integrity to use against these enemies who would like to conquer you. Insofar as you are concerned, you can hit them 'between the eye,' to use a figurative expression. You can triumph over them by disciplining yourselves to avoid them. You can say to the whole lot of them as David said to Goliath, 'Thou comest to me with a sword, and with a spear, and with a shield: but I come to thee in the name of the Lord of hosts, the God of the armies of Israel, who thou hast defied.'"Victory will be yours.... You have His power within you to sustain you. You have the right to ministering angels about you to protect you. Do not let Goliath frighten you. Stand your ground and hold your place, and you will be triumphant."
(President Gordon B. Hinckley, Ensign, May 1983, p46&51)
