A sermon on John 16:5-11.  Jesus says it is better for His disciples (and us) if He goes away and send them the Holy Spirit.  The Spirit will convict the world of sin because they do not believe in Jesus.  He will convict the world of righteousness because Jesus is going to the Father.  The Holy Spirit convicts the world of judgement because the prince of this world has been judged.

Isaiah 32:14-17, Acts 1:1-8, 2:1-4
