The Gospel affirms that men are called to be sons of GOD; to be perfect, as the heavenly Father is perfect. The correlative of this ideal view of man as he is meant to be is a sombre view of man as he actually is. "If we say that we have no sin we deceive ourselves, and the truth is not in us." "All have sinned, and come short of the glory of GOD." Sin is essentially a falling short, a missing of the mark, a failure to correspond with the purpose and the will of GOD. It need not necessarily involve--though of course it does in many instances involve--the deliberate transgression of a moral law which the conscience of the individual sinner recognizes as such. There are sins of omission as well as of commission, sins of ignorance as well as of deliberate intent. The fact that the conscience of a given individual does not accuse him, that he is not aware of himself as a sinner before GOD, is no evidence of his moral perfection, but rather the reverse. Jesus Christ, who possessed the surest as well as the sanest moral judgment the world has ever known, held deliberately that the open and acknowledged sinner, just because he was aware of his condition, was in a more hopeful spiritual state than the man who through ignorance of his own shortcomings believed himself to be righteous. The Pharisee, who compared himself with others to his own advantage, was condemned in the sight of GOD. The Publican, who would not so much as lift up his eyes unto heaven, but judging himself and his deeds by the standard of GOD'S holiness acknowledged himself a sinner, went away justified rather than the other. It is probably true that the ordinary man to-day is not worrying about his sins: but if so, the fact proves nothing except the secularity of his ideals and the shallowness of his sense of spiritual issues. It means, in short, that he has not taken seriously the standard of Christ. For the measure of a man's sin is simply the measure of the contrast between his character and the character of Christ. It is likely enough that many of us will never discover that we are sinners until we have deliberately tried and failed to follow Christ. The moment we do try seriously to follow Him, we become conscious of the presence within ourselves of "that horrid impediment which the Churches call sin." We discover that we are spiritually impotent: that there is that in us which is both selfish and self-complacent: that there is a "law of sin in our members" which is in conflict with the "law of the Spirit of life": and that "we have no power of ourselves to help ourselves." We are at the mercy of our own character, which has been wrongly moulded and formed amiss by the sins and follies, the self-indulgences and the moral slackness of our own past behaviour. We are, indeed, "tied and bound by the chain of our sins."
