Ezekiel 18:24

18:24 “But if a righteous man turns away from his righteousness and practices wrongdoing according to all the abominable practices the wicked carry out, will he live?

Hebrews 6:4-6

6:4 For it is impossible in the case of those who have once been enlightened, tasted the heavenly gift, become partakers of the Holy Spirit, 6:5 tasted the good word of God and the miracles of the coming age, 6:6 and then have committed apostasy, to renew them again to repentance, since they are crucifying the Son of God for themselves all over again and holding him up to contempt.
