It Is Possible to Fall From Grace
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. (Ezek. 18: 24.)
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 come, if they shall fall away, to renew them again unto repentance. (Heb. 6: 4, 5, 6.)
For if, after they have escaped the pollutions of the world through the knowledge of the Lord and Savior Jesus Christ, they are again entangled therein and overcome, the latter end is worse with them than the beginning. 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. (2 Peter 2: 20, 21.)
