When God was about to send Isaiah with a message to His people, He first permitted the prophet to look in vision into the holy of holies within the sanctuary. Suddenly the gate and the inner veil of the temple seemed to be uplifted or withdrawn, and he was permitted to gaze within, upon the holy of holies, where even the prophet’s feet might not enter. There rose before him a vision of Jehovah sitting upon a throne high and lifted up, while the train of His glory filled the temple. Around the throne were seraphim, as guards about the great King, and they reflected the glory that surrounded them. As their songs of praise resounded in deep notes of adoration, the pillars of the gate trembled, as if shaken by an earthquake. With lips unpolluted by sin, these angels poured forth the praises of God. “Holy, holy, holy, is the Lord of hosts,” they cried; “the whole earth is full of His glory.” See Isaiah 6:1-8L.
