John 16:11

of judgment, because the prince of this world is judged.

And that Person, the Holy Spirit, coming into the world, will convict the world. That is one special function and activity of the Spirit, to convict the unbelieving world on three counts, with regard to sin, justice, and judgment. This the Lord explains. Of sin the world stands accused and unable to deny the charge that they do not believe on Christ, because they willfully choose unbelief. That is the chief sin of the world, of the unbelievers, that they reject Christ and His Gospel. All other sins do not come into consideration if a person but believes in the forgiveness of sins. And therefore unbelief, which refuses to accept the forgiveness of sins, deliberately cuts itself off from salvation. This fact the Spirit impresses upon the minds and hearts of the unbelievers. "The world will not hear such preaching that they should all be sinners before God, and that their pious works have no value before Him, but that they rather through this crucified Christ must obtain mercy and salvation. Such unbelief against Christ becomes the sum and substance of all sins that lead a person into damnation, so that there is no help for him. " In close connection with this fact is the further truth that the Spirit convicts the unbelieving world of righteousness, since Jesus was going to the Father and would no longer be with them according to His visible presence. The true righteousness consists in this, that Christ, by His going to the Father, by His suffering, death, and resurrection, earned and prepared the righteousness which is acceptable with God. But the world wants nothing of Christ's blood and righteousness, preferring its own self-righteousness. And so both righteousness and salvation are lost to them by unbelief, as the Spirit will impress upon them. And He will finally convict them of the judgment, because the ruler of this world is judged and condemned. The redemption of Christ sealed the devil's doom; he has lost might and right with regard to mankind since sin was conquered by Jesus. This the Holy Ghost testifies to the hearts of the unbelievers, showing them that because of their unbelief they will have to share the doom of the devil, that they are condemned for rejecting the Conqueror of Satan. This also serves for the comfort of the believers, since they know that the world is even now convicted.
