Hebrews 6:4-8

For it is impossible to renew to repentance those who were once enlightened, who tasted the heavenly gift, who shared in the Holy Spirit, who tasted God’s good word and the powers of the coming age, and who have fallen away. This is because, to their own harm, they are recrucifying the Son of God and holding him up to contempt. For the ground that drinks the rain that often falls on it and that produces vegetation useful to those for whom it is cultivated receives a blessing from God. But if it produces thorns and thistles, it is worthless and about to be cursed, and at the end will be burned.
