4For it is impossible, in the case of those who have once been enlightened and have tasted of the heavenly gift and have been made partakers of the Holy Spirit, 5and have tasted the good word of God and the powers of the age to come, 6and then have fallen away, to restore them again to repentance, since they again crucify to themselves the Son of God and put Him to open shame.
