"And ye shall be hated of all men for my name's sake: but he that endureth to the end shall be saved" (Matthew 10:22).
The Book of Mormon: Another Testament of Jesus Christ adds more testimonies of our Lord and Redeemer Jesus Christ's words to Matthews writings:
"And it shall come to pass, that whoso repenteth and is baptized in my name shall be filled; and if he endureth to the end, behold, him will I hold guiltless before my Father at that day when I shall stand to judge the world. And he that endureth not unto the end, the same is he that is also hewn down and cast into the fire, from whence they can no more return, because of the justice of the Father"(3 Nephi 27:16-17).
"14 But, behold, my beloved brethren, thus came the voice of the Son unto me, saying: After ye have repented of your sins, and witnessed unto the Father that ye are willing to keep my commandments, by the baptism of water, and have received the baptism of fire and of the Holy Ghost, and can speak with a new tongue, yea, even with the tongue of angels, and after this should deny me, it would have been better for you that ye had not known me.
15 And I heard a voice from the Father, saying: Yea, the words of my Beloved are true and faithful. He that endureth to the end, the same shall be saved.
16 And now, my beloved brethren, I know by this that unless a man shall endure to the end, in following the example of the Son of the living God, he cannot be saved.
17 Wherefore, do the things which I have told you I have seen that your Lord and your Redeemer should do; for, for this cause have they been shown unto me, that ye might know the gate by which ye should enter. For the gate by which ye should enter is repentance and baptism by water; and then cometh a remission of your sins by fire and by the Holy Ghost.
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" (2 Nephi 31:12-20).
