Jesus testifies of himself

When the Lord Christ appeared to the brother of Jared, this is what He said. It is a strong testimony of his mission.

"Behold, I am he who was prepared from the foundation of the world to redeem my people. Behold, I am Jesus Christ. I am the Father and the Son. In me shall all mankind have life, and that eternally, even they who shall believe on my name; and they shall become my sons and my daughters." (Ether 3:14)
