2 Peter 2:20
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.
2 Peter 3:17
Ye therefore, beloved, seeing ye know [these things] before, beware lest ye also, being led away with the error of the wicked, fall from your own stedfastness.
2 Peter 2:21
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.
I will heal their backsliding, I will love them freely: for mine anger is turned away from him.
The backslider in heart shall be filled with his own ways: and a good man [shall be satisfied] from himself.
O Israel, return unto the LORD thy God; for thou hast fallen by thine iniquity.
Brethren, if a man be overtaken in a fault, ye which are spiritual, restore such an one in the spirit of meekness; considering thyself, lest thou also be tempted.
Now the just shall live by faith: but if [any man] draw back, my soul shall have no pleasure in him.
1 Chronicles 28:9
And thou, Solomon my son, know thou the God of thy father, and serve him with a perfect heart and with a willing mind: for the LORD searcheth all hearts, and understandeth all the imaginations of the thoughts: if thou seek him, he will be found of thee; but if thou forsake him, he will cast thee off for ever.
O LORD, the hope of Israel, all that forsake thee shall be ashamed, [and] they that depart from me shall be written in the earth, because they have forsaken the LORD, the fountain of living waters.
Thine own wickedness shall correct thee, and thy backslidings shall reprove thee: know therefore and see that [it is] an evil [thing] and bitter, that thou hast forsaken the LORD thy God, and that my fear [is] not in thee, saith the Lord GOD of hosts.
But we are not of them who draw back unto perdition; but of them that believe to the saving of the soul.
