Hebrews 6:4-8

For concerning those who were once enlightened and tasted of the heavenly gift, and were made partakers of the Holy Spirit, and tasted the good word of God and the powers of the age to come, and then fell away, it is impossible to renew them again to repentance; seeing they crucify the Son of God for themselves again, and put him to open shame. For the land which has drunk the rain that comes often on it and produces a crop suitable for them for whose sake it is also tilled, receives blessing from God; but if it bears thorns and thistles, it is rejected and near being cursed, whose end is to be burned.
