The Biblical counter-part to Satan, the Accuser, is the Paraklete. Jesus is our Paraklete (Advocate) with the Father (1 John 2:1), where He stands interceding for sinners, presenting His blood as evidence on our behalf. And from this heavenly council Jesus send forth the Holy Spirit to be our Paraklete on earth (see John 16:7-11). The Holy Spirit, then, speaks the heavenly verdict on earth. He stands in the courtroom of our conscience and testifies on our behalf, and the Holy Spirit accomplishes this through the Word, the Absolution (another forensic word).
It is in the Divine Service, where the Word is rightly preached and the sacraments rightly administered, that the Holy Spirit delivers the heavenly verdict to our conscience. It is where the heavenly declaration of righteousness is heard on the earth. It is where our conscience is made good, that is, it becomes a reflection of the heavenly council, the devil removed, his accusations silenced, and the blood and word of Jesus winning the day. It is for this purpose that Jesus has establish His church, and has instituted worship, so that he might deliver to us His righteousness. http://www.facebook.com/wolfmueller
