"Wherefore, if ye shall press forward, feasting upon the word of Christ, and endure to the end, behold, thus saith the Father: Ye shall have eternal life." (2 Nephi 31:20)

"And Jesus when he was baptized, went up straightway out of the water; and John saw, and lo, the heavens were opened unto him, and he saw the Spirit of God descending like a dove and lighting upon Jesus. And lo, he heard a voice from heaven, saying, This is my beloved Son, in whom I am well pleased. Hear ye him." (Matthew 3:46, Inspired Version)

"And behold, the third time they did understand the voice which they heard; and it said unto them:  Behold my Beloved Son, in whom I am well pleased, in whom I have glorified my name—hear ye him." (3 Nephi 11:7)

"It no sooner appeared than I found myself delivered from the enemy which held me bound. When the light rested upon me I saw two Personages, whose brightness and glory defy all description, standing above me in the air. One of them spake unto me, calling me by name and said, pointing to the other—This is My Beloved Son. Hear Him!" (Joseph Smith History 1:17)
