Hebrews 6

4 For itis impossible for those who were once enlightened, and have tasted *(John 4:10); Eph. 2:8the heavenly gift, and *(Gal. 3:2, 5); Heb. 2:4have become partakers of the Holy Spirit, 5 and have tasted the good word of God and the powers of the age to come, 6 if they fall away, to renew them again to repentance, *Heb. 10:29since they crucify again for themselves the Son of God, and put Him to an open shame.
