John Wesley on John 16:8

He - Observe his twofold office; toward the world, John 16:8, &c; toward believers, John 16:12, &c: will convince - All of the world - Who do not obstinately resist, by your preaching and miracles, of sin, and of righteousness, and of judgment - He who is convinced of sin either accepts the righteousness of Christ, or is judged with Satan. An abundant accomplishment of this we find in the Acts of the Apostles.
