New Testament (KJV) Hebrews 6:4-8
For it is impossible for those who were once enlightened, and have tasted of the heavenly gift, and were made partakers of the Holy Ghost,
And have tasted the good word of God, and the powers of the world to come1
If they shall fall away, to renew them again unto repentance; seeing they crucify to themselves the Son of God afresh, and put him to an open shame.
For the earth which drinketh in the rain that cometh oft upon it, and bringeth forth herbs meet for them by whom it is dressed, receiveth blessing from God:
But that which beareth thorns and briers is rejected, and is nigh unto cursing; whose end is to be burned.
New Testament (KJV) Luke 18:29-30
And he said unto them, Verily I say unto you, There is no man that hath left house, or parents, or brethren, or wife, or children, for the kingdom of God's sake,
Who shall not receive manifold more in this present time, and in the world to come1
New Testament (KJV) Mark 10:29-31
And Jesus answered and said, Verily I say unto you, There is no man that hath left house, or brethren, or sisters, or father, or mother, or wife, or children, or lands, for my sake, and the gospel's,
But he shall receive an hundredfold now in this time, houses, and brethren, and sisters, and mothers, and children, and lands, with persecutions; and in the world to come1
But many that are first shall be last; and the last first.
New Testament (KJV) Matthew 12:31-32
Wherefore I say unto you, All manner of sin and blasphemy shall be forgiven unto men: but the blasphemy against the Holy Ghost shall not be forgiven unto men.
And whosoever speaketh a word against the Son of man, it shall be forgiven him: but whosoever speaketh against the Holy Ghost, it shall not be forgiven him, neither in this world, neither in the world to come1
Doctrine and Covenants 76:31-38
Thus saith the Lord concerning all those who know my power, and have been made partakers thereof, and suffered themselves through the power of the devil to be overcome, and to deny the truth and defy my power--
They are they who are the sons of perdition, of whom I say that it had been better for them never to have been born;
For they are vessels of wrath, doomed to suffer the wrath of God, with the devil and his angels in eternity;
Concerning whom I have said there is no forgiveness in this world nor in the world to come1
Having denied the Holy Spirit after having received it, and having denied the Only Begotten Son of the Father, having crucified him unto themselves and put him to an open shame.
These are they who shall go away into the lake of fire and brimstone, with the devil and his angels--
And the only ones on whom the second death shall have any power;
Yea, verily, the only ones who shall not be redeemed in the due time of the Lord, after the sufferings of his wrath.
Doctrine and Covenants 84:40-41
Therefore, all those who receive the priesthood, receive this oath and covenant of my Father, which he cannot break, neither can it be moved.
But whoso breaketh this covenant after he hath received it, and altogether turneth therefrom, shall not have forgiveness of sins in this world nor in the world to come1
