The four parts of the simile and of the application correspond.
_First_, drinking in the rain that often comes upon the land corresponds to being once enlightened, tasting of the heavenly gift, being made partakers of the Holy Ghost, and tasting the good word of God and the powers of the world to come. The rain descends on all the land and gives it its natural richness. The question whether the Apostle speaks of converted or unconverted men is entirely beside the purpose, and may safely be relegated to the limbo of misapplied interpretations. No doubt the controversy between Calvinists and Arminians concerning final perseverance and the possibility of a fall from a state of grace is itself vastly important. But the question whether the gifts mentioned are bestowed on an unconverted man is of no importance to the right apprehension of the Apostle's meaning. We must be forgiven for thinking he had it not in his mind. It is more to the purpose to remind ourselves that all these excellences are regarded by the Apostle as gifts of God, like the oft-descending rain, not as moral qualities in men. He mentions the one enlightenment produced by the one revelation of God in His Son. It may be compared to the opening of blind eyes or the startled waking of the soul by a great idea. To taste the heavenly gift is to make trial of the new truth. To be made partakers of the Holy Ghost is to be moved by a supernatural enlightening influence. To taste the good word of God is to discern the moral beauty of the revelation. To taste the powers of the world to come is to participate in the gifts of power which the Spirit divides to each one severally even as He will. All these things have an intellectual quality. Faith in Christ and love to God are purposely excluded. The Apostle brings together various phases of our spiritual intelligence, the gift of illumination, which we sometimes call genius, sometimes culture, sometimes insight, the faculty that ought to apprehend Christ and welcome the revelation in the Son. If these high gifts are used to scoff at the Son of God, and that with the persistence that can spring only from the pride and self-righteousness of unbelief, renewal is impossible.
_Second_, the negative result of not bringing forth any useful herbs corresponds to falling away.[100] God has bestowed His gift of enlightenment, but there is no response of heart and will. The soul does not lay hold, but drifts away.
_Third_, the positive result of bearing thorns and thistles corresponds to crucifying to themselves the Son of God afresh and putting Him to an open shame. The gifts of God have been abused, and the contrary of what He, in His care for men, intended the earth to produce, is the result. The Divine gift of spiritual enlightenment has been itself turned into a very genius of cynical mockery. The Son of God has already been once crucified amid the awful scenes of Gethsemane and Calvary. The agony and bloody sweat, the cry of infinite loneliness on the Cross, the tender compassion of the dying Jesus, the power of His resurrection--all this is past. One bitterness yet remains. Men use God's own gift of spiritual illumination to crucify the Son afresh. But they crucify Him only for themselves.[101] When the sneer has died away on the scoffer's lips, nothing is left. No result has been achieved in the moral world. When Christ was crucified on Calvary, His death changed for ever the relations of God and men. When He is crucified in the reproach of His enemies, nothing has been accomplished outside the scoffer's little world of vanity and pride.
_Fourth_, to be nigh unto a curse and to be given in the end to be burned corresponds to the impossibility of renewal. The illustration requires us to distinguish between "falling away" and "crucifying the Son of God afresh and putting Him to an open shame."[102] The land is doomed to be burned because it bears thorns and thistles. God renders men incapable of repentance, not because they have fallen away once or more than once, but because they scoff at the Son, through Whom God has spoken unto us. The terrible impossibility of renewal here threatened applies, not to apostasy (as the early Church maintained) nor to the lapsed (as the Novatianists held),[103] but to apostasy combined with a cynical, scoffing temper that persists in treading the Son of God under foot. Apostasy resembles the sin against the Son of man; cynicism in reference to the Son of man comes very near the sin against the Holy Ghost. This sin is not forgiven, because it hardens the heart and makes repentance impossible. It hardens the heart, because God is jealous of His Son's honour, and punishes the scoffer with the utter destruction of the spiritual faculty and with absolute inability to recover it. This is not the mere force of habit. It is God's retribution, and the Apostle mentions it here because the text of the whole Epistle is that God has spoken unto us in His Son.
