Hebrews 6:4-6

CLV(i) 4 For it is impossible for those once enlightened, besides tasting the celestial gratuity and becoming partakers of holy spirit, 5 and tasting the ideal declaration of God, besides the powerful deeds of the impending eon, 6 and falling aside, to be renewing them again to repentance while crucifying for themselves the Son of God again and holding Him up to infamy."
