Pastor Jeske continues his series on The Divine Service with a bible study on the Sanctus: Holy is the Lord God.  If any part of the service has been recognized as providing a glimpse of heaven, it's the Sanctus: “Holy, holy, holy, Lord God of Sabaoth, heaven and earth are full of your glory.”  This is the eternal song of the angels who hover over the throne of God in the vision of heaven that was given to Isaiah (Is. 6:1-4). Such was the splendor of their song that the very foundations of the threshold of the temple trembled at the sound.
