Hebrews 6:4-9

Concerning those who were once enlightened, having tasted the heavenly gift, being partakers of the HOLY SPIRIT, and who tasted the goodness of the word of GOD and the powers of the age to come - if they then fall away, it is impossible to renew them to repentance, because to their loss they crucify the SON of GOD anew, and subject him to open shame. For land which drinks the rain that often falls on it, and then produces a crop suitable for whom it was farmed, receives a blessing from GOD. But land that produces thorns and thistles is rejected and near to being cursed. In the end it will be burned. But, beloved, even as we speak of such things, we are persuaded of better things for you - things that accompany salvation.
