This song was written by Samuel Trevor Francis (1834-1925) after a serious bout with depression. As his biographers tell the story, one winter night as a teen, Francis was walking across the Hungerford Bridge over the River Thames. He paused and stared down into the depths of the river below. He contemplated plunging into the icy waters and ending everything. But instead, John 3:3 came into his mind, “Truly, truly, I say unto you, unless one is born again he cannot see the kingdom of God.” Francis repented and this reformation of heart prompted him to begin writing poetry and lyrics. One of the songs that came from this was “O the Deep, Deep Love of Jesus.”
Initially, this song had four verses, though since its appearance in the 1911 The Song Companion to the Scriptures, it is usually shortened to three. The text echoes the Apostle Paul’s description of the strength required to “comprehend with all the saints what is the breadth and length and height and depth” of the love of Christ (Eph. 3:18). The picture is of a limitless ocean.
