John 3

[14] And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up:
[15] That whosoever believeth in him should not perish, but have eternal life.

John 17

[3] And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent.

Romans 6

[23] For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord.

2 Nephi 31

[18] And then are ye in this strait and narrow path which leads to eternal life; yea, ye have entered in by the gate; ye have done according to the commandments of the Father and the Son; and ye have received the Holy Ghost, which witnesses of the Father and the Son, unto the fulfilling of the promise which he hath made, that if ye entered in by the way ye should receive.

[19] And now, my beloved brethren, after ye have gotten into this strait and narrow path, I would ask if all is done? Behold, I say unto you, Nay; for ye have not come thus far save it were by the word of Christ with unshaken faith in him, relying wholly upon the merits of him who is mighty to save.

[20] Wherefore, ye must press forward with a steadfastness in Christ, having a perfect brightness of hope, and a love of God and of all men. 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.

Doctrine & Covenants 14

[7] And, if you keep my commandments and endure to the end you shall have eternal life, which gift is the greatest of all the gifts of God.
