John 16:7 Nevertheless, I tell you the truth: it is to your advantage that I go away, for if I do not go away, the Helper will not come to you. But if I go, I will send him to you. And when he comes, he will convict the world concerning sin and righteousness and judgment: concerning sin, because they do not believe in me; concerning righteousness, because I go to the Father, and you will see me no longer; concerning judgment, because the ruler of this world is judged.
John 7:39 Now this he said about the Spirit, whom those who believed in him were to receive, for as yet the Spirit had not been given, because Jesus was not yet glorified.
John 14:16-17 And I will ask the Father, and he will give you another Helper, to be with you forever, even the Spirit of truth, whom the world cannot receive, because it neither sees him nor knows him. You know him, for he dwells with you and will be in you.
John 14:26 But the Helper, the Holy Spirit, whom the Father will send in my name, he will teach you all things and bring to your remembrance all that I have said to you.
John 15:26 “But when the Helper comes, whom I will send to you from the Father, the Spirit of truth, who proceeds from the Father, he will bear witness about me.
He will convict the world of sin, and of righteousness, and of judgment: Sin is the truth about man, righteousness is the truth about God, judgment is the inevitable combination of these two truths. (Guzik)
“Each man’s conscience has some glimmering of light on each of these; some consciousness of guilt, some sense of right, some power of judgment of what is transitory and worthless; but all these are unreal and unpractical, till the convicting work of the Spirit has wrought in him.” (Alford)
The ancient Greek work translated convict has a broader range of meaning than simply our word convict, especially as it is understood in a legal sense. It also carries the ideas to expose, to refute, and to convince (Bruce). This is the work of the Holy Spirit in the world and in individual hearts; to convince and convict of these truths. It is a serious thing to resist and reject this work of the Holy Spirit, which is especially prominent and powerful in seasons of great spiritual advance. “The Spirit does not merely accuse men of sin, he brings to them an inescapable sense of guilt so that they realize their shame and helplessness before God.” (Tenney)
“The Spirit is the ‘advocate’ or helper of those who believe in Jesus, their counsel for the defence. But in relation to unbelievers, to the godless world, he acts as counsel for the prosecution.” (Bruce) It’s important to have the Spirit of God to defend rather than to convict.
In the great awakening of 1860-61 in Great Britain, a high-ranking army officer described the conviction of sin in his Scottish town: “Those of you who are ease have little conception of how terrifying a sight it is when the Holy Spirit is pleased to open a man’s eyes to see the real state of heart. Men who were thought to be, and who thought themselves to be good, religious people… have been led to search into the foundation upon which they were resting, and have found all rotten, that they were self-satisfied, resting on their own goodness, and not upon Christ. Many turned from open sin to lives of holiness, some weeping for joy for sins forgiven.” (J. Edwin Orr, The Second Evangelical Awakening in Britain)
It is unbelief, the rejection of Jesus, which ultimately proves one to be guilty. The Holy Spirit will tell the world of the importance of trusting in, relying on, and clinging to Jesus to avoid this sin. “The essence of sin is unbelief, which is not simply a casual skepticism nor a difference of opinion; rather, it is a total rejection of God’s messenger and message.” (Tenney) It is a vague kind of skepticism which is one of the most common spiritual diseases in man.
