John 16:4-15 highlights the importance of Jesus’ teaching about the ministry of the Holy Spirit. His task in the world is to convict people of unbelief, righteousness and judgement and He does this by using the Word of God and applying it to the hearts of those who hear or read it. The Spirit’s role among God’s people is to enable us to remember and grasp the teaching and the words of Jesus and to promote the wonder and majesty of Jesus as the Saviour of all who believe.
