Every individual born to earth is given a detecting capability, a divinely appointed gift to distinguish truth from error. We call it our conscience. God calls it the Spirit of Christ. When we properly use this gift, we are naturally drawn to truth and repelled from error.
Satan does not want us to use that divine gift. He camouflages his true purpose behind appealing temptations. His program is to turn our interest to self. He wants us to become so engrossed in the attempt to satisfy personal appetites and desires that we lose the ability to distinguish truth from error. Such a course of life does not, cannot, will not ever bring happiness. – Richard G. Scott, “Happiness Now and Forever,” Ensign (CR) November 1979
