Notice of which sin it is that the Holy Spirit convinces men—the sin of unbelief in Jesus Christ, “Of sin because they believe not on Me,” says Jesus. Not the sin of stealing, not the sin of drunkenness, not the sin of adultery, not the sin of murder, but the sin of unbelief in Jesus Christ. The one thing that the eternal God demands of men is that they believe on Him whom He hath sent (John vi. 29). And the one sin that reveals men’s rebellion against God and daring defiance of Him is the sin of not believing on Jesus Christ, and this is the one sin that the Holy Spirit puts to the front and emphasizes and of which He convicts men. This was the sin of which He convicted the 3,000 on the Day of Pentecost. Doubtless, there were many other sins in their lives, but the one point that the Holy Spirit brought to the front through the Apostle Peter was that the One whom they had rejected was their Lord and Christ, attested so to be by His resurrection from the dead (Acts ii. 22-36). “And _when they heard this_ (namely, that He whom they had rejected was Lord and Christ) they were pricked in their hearts.” This is the sin of which the Holy Spirit convinces men to-day. In regard to the comparatively minor moralities of life, there is a wide difference among men, but the thief who rejects Christ and the honest man who rejects Christ are alike condemned at the great point of what they do with God’s Son, and this is the point that the Holy Spirit presses home. The sin of unbelief is the most difficult of all sins of which to convince men. The average unbeliever does not look upon unbelief as a sin. Many an unbeliever looks upon his unbelief as a mark of intellectual superiority. Not unfrequently, he is all the more proud of it because it is the only mark of intellectual superiority that he possesses. He tosses his head and says, “I am an agnostic;” “I am a skeptic;” or, “I am an infidel,” and assumes an air of superiority on that account. If he does not go so far as that, the unbeliever frequently looks upon his unbelief as, at the very worst, a misfortune. He looks for pity rather than for blame. He says, “Oh, I wish I could believe. I am so sorry I cannot believe,” and then appeals to us for pity because he cannot believe, but when the Holy Spirit touches a man’s heart, he no longer looks upon unbelief as a mark of intellectual superiority; he does not look upon it as a mere misfortune; he sees it as the most daring, decisive and damning of all sins and is overwhelmed with a sense of his awful guilt in that he had not believed on the name of the only begotten Son of God.
II. But the Holy Spirit not only convicts of sin, _He convicts in respect of righteousness_.
He convicts the world in respect of righteousness because Jesus Christ has gone to the Father, that is He convicts (convinces with a convincing that is self-condemning) the world of Christ’s righteousness attested by His going to the Father. The coming of the Spirit is in itself a proof that Christ has gone to the Father (cf. Acts ii. 33) and the Holy Spirit thus opens our eyes to see that Jesus Christ, whom the world condemned as an evil-doer, was indeed the righteous One. The Father sets the stamp of His approval upon His character and claims by raising Him from the dead and exalting Him to His own right hand and giving to Him a name that is above every name. The world at large to-day claims to believe in the righteousness of Christ but it does not really believe in the righteousness of Christ: it has no adequate conception of the righteousness of Christ. The righteousness which the world attributes to Christ is not the righteousness which God attributes to Him, but a poor human righteousness, perhaps a little better than our own. The world loves to put the names of other men that it considers good alongside the name of Jesus Christ. But when the Spirit of God comes to a man, He convinces him of the righteousness of Christ; He opens his eyes to see Jesus Christ standing absolutely alone, not only far above all men but “far above all principality and power and might and dominion, and every name that is named, not only in this world but also in that which is to come” (Eph. i. 21).
III. The Holy Spirit also convicts the world of judgment.
