It is "sin," _i.e._, "missing one's aim;" in which profound word is contained the truth that all sin is a blunder, shooting wide of the true goal, if regard be had to the end of our being, and not less wide if regard be had to our happiness. It ever misses the mark; and the epitaph might be written over every sinner who seeks pleasure at the price of righteousness, "Thou fool." Nor less pregnant with meaning is the psalmist's emphatic acknowledgment, "Against Thee, Thee only have I sinned." He is not content with looking upon his evil in itself, or in relation only to the people who had suffered by it; he thinks of it in relation to God. He had been guilty of crimes against Bathsheba and Uriah, and even the rough soldier whom he made his tool, as well as against his whole subjects; but, dark as these were, they assumed their true character only when they were discerned as done against God. "Sin," in its full sense, implies "God" as its correlative. We transgress against each other, but we sin against Him. Nor does the psalmist stop here. He has acknowledged the tangled multiplicity and dreadful unity of his evil, he has seen its inmost character, he has learned to bring his deed into connection with God; what remains still to be confessed? He laments, and that not as extenuation (though it be explanation), but as aggravation, the sinful nature in which he had been born. The deeds had come from a source--a bitter fountain had welled out this blackness. He himself is evil, therefore he has done evil. The sin is his; he will not contest his full responsibility; and its foul characteristics declare the inward foulness from which it has flowed--and that foulness is himself. Does he therefore think that he is less to blame? By no means. His acknowledgment of an evil nature is the very deepest of his confessions, and leads not to a palliation of his guilt, but to a cry to Him who alone can heal the inward wound; and as He can purge away the transgressions, can likewise stanch their source, and give him to feel within "that he is healed from that plague."
