|Music: Phoebe P. Knapp|
|Words: Fanny J. Crosby|
Crosby was visiting her friend Phoebe Knapp as the Knapp home was having a large pipe organ installed. The organ was incomplete, so Mrs. Knapp, using the piano, played a new melody she had just composed. When Knapp asked Crosby, "What do you think the tune says?", Crosby replied, "Blessed assurance, Jesus is mine."
The hymn appeared in the July 1873 issue of Palmer's Guide to Holiness and Revival Miscellany, a magazine printed by Dr. and Mrs. W. C. Palmer of 14 Bible House, New York City. It appeared on page 36 (the last page) with complete text and piano score, and indicated it had been copyrighted by Crosby that year. It is not certain that this was the first printing of the hymn, but it certainly helped to popularize what became one of the most beloved hymns of all time. The popular song does not reflect the biblical teachings, for example from the Gospels and the teachings of the Apostles. It does not have an Orthodox Christian theology, rather reflects the popular Christianity of her days. The Christology of the song shows only Crosby's own poetic imagination.
Because of Crosby's lyrics, the tune is now called "Assurance".
Based on an interpretation 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." (King James Version)
Blessed assurance, Jesus is mine!
O what a foretaste of glory divine!
Heir of salvation, purchase of God,
Born of His Spirit, washed in His blood.
This is my story, this is my song,
praising my Savior all the day long;
this is my story, this is my song,
praising my Savior all the day long.
Perfect submission, perfect delight!
Visions of rapture now burst on my sight;
Angels descending bring from above
Echoes of mercy, whispers of love.
Perfect submission, all is at rest!
I in my Savior am happy and blest,
Watching and waiting, looking above,
Filled with His goodness, lost in His love.
