To this end it teaches this great and momentous truth: that wrong and injustice once done cannot be undone; but are eternal in their consequences; once committed, are numbered with the irrevocable Past; that the wrong that is done _contains_ its own retributive penalty as surely and as naturally as the acorn contains the oak. Its consequences are its punishment; it needs no other, and can have no heavier; they are involved in its commission, and cannot be separated from it. A wrong done to another is an injury done to our own Nature, an offence against our own souls, a disfiguring of the image of the Beautiful and Good. Punishment is not the execution of a sentence, but the occurrence of an effect. It is ordained to follow guilt, not by the decree of God as a judge, but by a law enacted by Him as the Creator and Legislator of the Universe. It is not an arbitrary and artificial annexation, but an ordinary and logical consequence; and therefore must be borne by the wrong-doer, and through him may flow on to others. It is the decision of the infinite justice of God, in the form of law. There can be no interference with, or remittance of, or protection from, the natural effects of our wrongful acts. God will not interpose between the cause and its consequence; and in that sense there can be no forgiveness of sins. The act which has debased our soul may be repented of, may be turned from; but the injury is done. The debasement may be redeemed by after-efforts, the stain obliterated by bitterer struggles and severer sufferings; but the efforts and the endurance which might have raised the soul to the loftiest heights are now exhausted in merely regaining what it has lost. There must always be a wide difference between him who only ceases to do evil, and him who has always done well. He will certainly be a far more scrupulous watcher over his conduct, and far more careful of his deeds, who believes that those deeds will inevitably bear their natural consequences, exempt from after intervention, than he who believes that penitence and pardon will at any time unlink the chain of sequences. Surely we shall do less wrong and injustice, if the conviction is fixed and embedded in our souls that everything done is done irrevocably, that even the Omnipotence of God cannot _uncommit_ a deed, cannot make that _undone_ which has _been done_; that every act of ours _must_ bear its allotted fruit, according to the everlasting laws,--must remain forever ineffaceably inscribed on the tablets of Universal Nature.
