Read John ch 16:7-11
V7: In fact, when the Holy Spirit is given, it will be better for them (and all succeeding Christians), for Jesus in His earthly life could only be in one place, and only with those in that same place – but the Spirit will be with every believer, throughout the age, and in all the world.
V8: And the work of the Spirit will be to bring conviction to the world of these 3 things …
V9: Of sin, because they do not believe in Jesus – ( see John 3:18 ). How are we to understand this work of conviction? Surely, it is twofold. For those who will believe, the Spirit shows them their sin of unbelief and opens their hearts to trust in Jesus. For those who do not, they will be convicted of this sin in the final judgement. How solemn these things are!
V10: Of Righteousness because He goes to the Father. Again,- His Resurrection and Ascension is the proof that God has accepted His sacrifice, that He was indeed the spotless lamb of God, the righteous One. Wonder of grace, that He gives that righteousness to all who trust in Him, as He bears their sin. ( 2 Corinthians 5:21) believers are brought to this awareness by the Spirit. The unbeliever will face the righteous Jesus as judge.
V11: Of judgement – because Satan is judged, defeated and condemned by Christ’s victory on the cross ( Colossians 2:15 ) Again, believers are convicted of this truth and know the victory, by God’s grace – unbelievers will face the same judgement. Do you know that you are saved from that judgement, because Christ has born it for you?
