Hebrews 6:4-6

Living_Oracles(i) 4 For it is impossible to renew again to reformation those who have been once enlightened, and have tasted of the heavenly gift, and have been made partakers of the Holy Spirit, 5 and have tasted the good word of God, and the powers of the age which was to come, 6 and yet have fallen away, crucifying again to themselves the Son of God and exposing him to contempt.
