“Blessed Assurance” is presented here as a lead sheet in G major. The page includes the melody on a single treble staff, chord symbols above the notes, and three verses of lyrics by Fanny J. Crosby placed under the melody. Instead of a written-out piano accompaniment, this version gives the tune, harmony, and text so it can be used for singing, simple accompaniment, arranging, or improvisation.

Measures 1–5 present the opening verse phrase, “Blessed assurance, Jesus is mine!” The melody begins with a confident hymn-like shape, while the chord symbols move through G, C/G, D/A, A7, and D. The stacked lyrics allow all three verses to fit under the same melody without needing separate pages.

Measures 6–8 continue the verse with “Heir of salvation, purchase of God.” The harmony moves through G, C/G, C, A minor, G/D, and D7, giving the phrase a clear progression back toward the home key. The melody remains direct and singable, matching the strong testimony character of the hymn text.

Measures 9–12 begin the refrain, “This is my story, this is my song.” The melody becomes especially memorable here, with repeated phrase shapes and a more declarative sound. The chord symbols move through G, C, G, C, G/B, D/A, A, D, and D7, giving the refrain enough harmonic motion to support a fuller accompaniment.

Measures 13–15 complete the refrain with “Praising my Savior all the day long.” The harmony returns through G, C/G, C, A minor/C, G/D, D7, and G, ending with a clear cadence in the home key. The repeated refrain text gives the lead sheet a strong congregational ending while still leaving room for the performer to create a simple or more developed accompaniment.

Interesting fact: “Blessed Assurance” was written in 1873, with words by Fanny J. Crosby and music by Phoebe Palmer Knapp. Crosby was one of the most prolific hymn writers in history, and this hymn became one of her most famous because the refrain feels personal, direct, and easy for a congregation to remember.
