We cannot depend on the testimonies of other people. We need to know for ourselves. President Gordon B. Hinckley said, "Every Latter-day Saint has the responsibility to know for himself or herself with a certainty beyond doubt that Jesus is the resurrected, living Son of the living God." The source of this sure knowledge and firm conviction is divine revelation, "for the testimony of Jesus is the spirit of prophecy." We receive this testimony when the Holy Spirit speaks to the spirit within us. We will receive a calm and unwavering certainty that will be the source of our testimony and conviction irrespective of our culture, race, language, or socioeconomic background. These promptings of the Spirit, rather than human logic alone, will be the true foundation upon which our testimony will be built. The core of this testimony will always be the faith in and the knowledge of Jesus Christ and His divine mission.
