Here is a bit of what Fanny Crosby had to say about how the song came into being:Sometimes a tune is furnished me for which to write the words. The hymn titled Blessed Assurance was made in this manner. My dear friend Phoebe Palmer Knapp (Mrs. Joseph), so well-known as a writer and singer of most excellent music and as an aid and inspiration to all who knew her, had composed the tune; and it seemed to me one of the sweetest I had heard for a long time. She asked me what it said. I replied, Blessed assurance. I felt while bringing the words and tones together that the air and the hymn were intended for each other.-from Fanny Crosby's Memories This song and To God Be the Glory are two of her most widely published songs, and this song appears in 951 hymnals, according to Himnary.org.This arrangement is for 4 part male harmony (TTBB) a cappella.
