'He shall convict the world of sin.' The outstanding first characteristic of the whole Gospel message is the new gravity which it attaches to the fact of sin, the deeper meaning which it gives to the word, and the larger scope which it shows its blighting influences to have had in humanity. Apart from the conviction of sin by the Spirit using the word proclaimed by disciples, the world has scarcely a notion of what sin is, its inwardness, its universality, the awfulness of it as a fact affecting man's whole being and all his relations to God. All these conceptions are especially the product of Christian truth. Without it, what does the world know about the poison of sin? And what does it care about the poison until the conviction has been driven home to the reluctant consciousness of mankind by the Spirit wielding the word? This conviction comes first in the divine order. I do not say that the process of turning a man of the world into a member of Christ's Church always begins, as a matter of fact, with the conviction of sin. I believe it most generally does so; but without insisting upon a pedantic adherence to a sequence, and without saying a word about the depth and intensity of such a conviction, I am here to assert that a Christianity which is not based upon the conviction of sin is an impotent Christianity, and will be of very little use to the men who profess it, and will have no power to propagate itself in the world. Everything in our conception of the Gospel of Jesus Christ and of His work for us depends upon what we think about this primary fact of man's condition, that he is a sinful man. The root of all heresy lies there. Every error that has led away men from Jesus Christ and His Cross may be traced up to defective notions of sin and a defective realisation of it. If I do not feel as the Bible would have me feel, that I am a sinful man, I shall think differently of Jesus Christ and of my need of Him, and of what He is to me. Christianity may be to me a system of beautiful ethics, a guide for life, a revelation of much precious truth, but it will not be the redemptive power without which I am lost. And Jesus Christ will be shorn of His brightest beams, unless I see Him as the Redeemer of my soul from sin, which else would destroy and is destroying it. Is Christianity merely a better morality? Is it merely a higher revelation of the divine Nature? Or does it _do_ something as well as _say_ something, and what does it do? Is Jesus Christ only a Teacher, a Wise Man, an Example, a Prophet, or is He the Sacrifice for the sins of the world? Oh, brethren, we must begin where this text begins; and our whole conception of Him and of His work for us must be based upon this fact, that we are sinful and lost, and that Jesus Christ, by His sweet and infinite love and all-powerful sacrifice, is our soul's Redeemer and our only Hope. The world has to be convicted and convinced of sin as the first step to its becoming a Church.
The next step of this divine Spirit's conviction is that which corresponds to the consciousness of sin, the dawning upon the darkened soul of the blessed sunrise of righteousness. The triple subjects of conviction must necessarily belong to the world of which our Lord is speaking. It must be the world that is convinced, and it must be the world's sin and the world's righteousness and the world's judgment of which my text speaks. How, then, can there follow on the conviction of sin as mine a conviction of righteousness as mine? I know but one way, 'Not having mine own righteousness, which is of the law, but that which is of God through faith.' When a man is convinced of sin, there will dawn upon the heart the wondrous thought that a righteousness may be his, given to him from above, which will sweep away all his sin and make him righteous as Christ is righteous. That conviction will never awake in its blessed and hope-giving power unless it be preceded by the other. It is of no use to exhibit medicine to a man who does not know himself diseased. It is of no use to talk about righteousness to a man who has not found himself to be a sinner. And it is of as little use to talk to a man of sin unless you are ready to tell him of a righteousness that will cover all his sin. The one conviction without the other is misery, the second without the first is irrelevant and far away.
