I saw the Lord. Seated on a lofty throne, and the train of His robe filled the Temple.
Around Him were angels, with six mighty wings. With two they covered their faces, with two they covered their feet,and with two they fly, and sing.
Holy holy holy is the Lord almighty!
The whole earth is filled with His Glory.
The Glorious singing shook the Temple to it's foundations, and the entire sanctuary was filled with smoke.
Then I said "Whoa is me for I am ruined. For I am unclean and so are all my kind. For my eyes have seen the King, The Lord Almighty.
Then one of the angels flew over to the altar, and he picked up a buning coal with a pair of tongs. He touched my lips and said "Now your guilt is removed and your sins are forgiven".
Can you imagine? Isaiah saw God in all His glory! How difficult is that to get your mind around? It is not even something I can comprehend. Can you?
