4 For it is impossible to renew to repentance those who were once enlightened, who tasted the heavenly gift, who shared in the Holy Spirit,z 5 who tasted God’s good word and the powers of the coming age, 6 and who have fallen away. This is because,A to their own harm, they are recrucifying the Son of God and holding him up to contempt.a 7 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.
