Hebrews 6:4-6

For it is impossible, in the case of those a who have once been enlightened, who have tasted b the heavenly gift, and c have shared in the Holy Spirit, and d have tasted the goodness of the word of God and the powers of the age to come, and e then have fallen away, to restore them again to repentance, since f they are crucifying once again the Son of God to their own harm and holding him up to contempt.
