Forgiveness and Retribution
'Thou wast a God that forgavest them, though Thou tookest vengeance of their inventions.'--PSALM xcix. 8. When the prophet Isaiah saw the great vision which called him to service, he heard from the lips of the seraphim around the Throne the threefold ascription of praise: 'Holy! holy! holy!
