Hebrews 6:6-8
6:6 and then have committed apostasy, to renew them again to repentance, since they are crucifying the Son of God for themselves all over again and holding him up to contempt.
6:7 For the ground that has soaked up the rain that frequently falls on it and yields useful vegetation for those who tend it receives a blessing from God.
6:8 But if it produces thorns and thistles, it is useless and about to be cursed; its fate is to be burned.
