Elder H. Burke Peterson, formerly of the Seventy, said, "As we go through life, we ofttimes build a rock wall between ourselves and heaven. This wall is built by our unrepented sins, … [with] stones of many different sizes and shapes. There could be stones because we have been unkind to someone. Criticism of leaders or teachers may add another stone. … Vulgar thoughts and actions may add some rather large stones in this wall" ("Prayer—Try Again," Ensign, June 1981, 73).
Because of the wall we might think, "Heavenly Father doesn't hear," or "He doesn't answer," but it's because His counsel bounces off the wall we built! It is our challenge to tear this wall down, through repentance, obedience, and righteousness. Then we can be in tune with the Spirit.
