Hebrews 6:4-6

MNT(i) 4 For in the case of those who have been once for all enlightened and have tasted of the heavenly gift, 5 and become partakers of the Holy Spirit, and tasted the good word of God, and the powers of the Future Age, 6 and then fallen away, it is impossible to renew them again unto repentance. For they repeatedly crucify to themselves the Son of God afresh, and expose him to an open shame.
