Ezechiel 18:24
But when the righteous turneth away from his righteousness, and committeth iniquity, and doeth according to all the abominations that the wicked man doeth, shall he live? All his righteousness that he hath done shall not be mentioned: in his trespass that he hath trespassed, and in his sin that he hath sinned, in them shall he die.
Hébreux 6:4-6
4
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,
5
And have tasted the good word of God, and the powers of the world to come,
6
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.
Hébreux 10:32-39
32
But call to remembrance the former days, in which, after ye were illuminated, ye endured a great fight of afflictions;
33
Partly, whilst ye were made a gazingstock both by reproaches and afflictions; and partly, whilst ye became companions of them that were so used.
34
For ye had compassion of me in my bonds, and took joyfully the spoiling of your goods, knowing in yourselves that ye have in heaven a better and an enduring substance.
35
Cast not away therefore your confidence, which hath great recompence of reward.
36
For ye have need of patience, that, after ye have done the will of God, ye might receive the promise.
37
For yet a little while, and he that shall come will come, and will not tarry.
38
Now the just shall live by faith: but if any man draw back, my soul shall have no pleasure in him.
39
But we are not of them who draw back unto perdition; but of them that believe to the saving of the soul.
2 Pierre 2:20-22
20
For if after they have escaped the pollutions of the world through the knowledge of the Lord and Saviour Jesus Christ, they are again entangled therein, and overcome, the latter end is worse with them than the beginning.
21
For it had been better for them not to have known the way of righteousness, than, after they have known it, to turn from the holy commandment delivered unto them.
22
But it is happened unto them according to the true proverb, The dog is turned to his own vomit again; and the sow that was washed to her wallowing in the mire.
2 Jean 1:8
Look to yourselves, that we lose not those things which we have wrought, but that we receive a full reward.
