Hebrews 6:4-6

New King James Version

⁴ For it is impossible for those who were once enlightened, and have tasted ^(A)the heavenly gift, and ^(B)have become partakers of the Holy Spirit, ⁵ and have tasted the good word of God and the powers of the age to come, ^6 [a]if they fall away, to renew them again to repentance, ^(C)since they crucify again for themselves the Son of God, and put Him to an open shame.
