Mormon 3:21
And also that ye may believe the gospel of Jesus Christ, which ye shall have among you; and also that the Jews, the covenant people of the Lord, shall have other witness besides him whom they saw and heard, that Jesus, whom they slew, was the very Christ and the very God.
2 Nephi 26:12
And as I spake concerning the convincing of the Jews, that Jesus is the very Christ, it must needs be that the Gentiles be convinced also that Jesus is the Christ, the Eternal God.
