A major duty and obligation of church members and believers everywhere is to testify of Jesus Christ, that He lives and that He is the Son of God-the Savior of the world. A major purpose of the Bible and the Book of Mormon is to convince the world-both Jew and Gentile-that Jesus is the christ whose self-sacrifice was the perfect, infinite atonement for all mankind.
“Faith cometh by hearing.” As we bear testimony of Jesus Christ, more people will believe in Him, that He is. Faith in Christ is the first principle of the gospel. The foundation of one’s life must be faith in Jesus Christ, for this is life’s rock foundation that will never fail you.
