It might seem unlikely that a blind writer of hymns living in a slum and a wealthy woman living in a mansion would have anything in common — but Fanny Crosby, the blind hymn writer, was a humble woman with a number of distinguished friends. Grover Cleveland, who later became President of the United States, met Fanny Crosby as a young man, and they became lifelong friends.
The friend in the mansion was Phoebe Knapp, the daughter of a Methodist evangelist. When she was just sixteen years old, Phoebe married Joseph Fairchild Knapp, a young man who went on to found the Metropolitan Life Insurance Company. The Knapps worshiped at the John Street Methodist Church in lower Manhattan, which is where Fanny Crosby also worshiped — and so a friendship was born. Phoebe, the wealthy matron, often invited Fanny, the blind hymn writer, to her home.
Phoebe enjoyed music, and had a music room furnished with a collection of musical instruments. During one of Fanny’s visits, Phoebe invited her to the music room, where Phoebe sat down at the keyboard and played a tune that she had written. “What does that say,” she asked? Fanny clapped her hands in delight and said, “That says, ‘Blessed assurance, Jesus is mine!'” She then continued with other words of the hymn. Mrs. Knapp wrote the words down and fit them into the tune as we have it today.
Many people thought Fanny Crosby in 1873 finds inspiration for the song through the passage of Hebrews 10:22. ” Let us draw near with a true heart in full assurance of faith, having our hearts sprinkled from an evil conscience, and our bodies washed with pure water.” (KJV). Because she wrote the hymn on a whim. Though without any spiritual background it might be difficult to write down the text of inspiring hymn as blessed assurance in a very short time like she did.
The full text and score of the hymn were published on page 36 of a magazine called Issue of Palmer’s Guide to Holiness and Revival Miscellany in July 1873. Specifically, the magazine is printed by the parent of Mrs. Knapp who is an evangelist. However, there is no source that confirmed that the magazine was the first to print Blessed Assurance Hymn.
But it actually assisted in making the inspiring hymn popular as of today. The tune is called Blessed Assurance or Assurance in relation to Fanny Crosby’s text.
During her lifetime, Fanny Crosby wrote eight thousand hymns, many of which became famous — but “Blessed Assurance” just might be the most famous of all.
