'This hymn was written after several [?] traumatic events in Horatio Spafford’s life. The first was the death of his only son in 1871, shortly followed by the great Chicago Fire which ruined him financially (he had been a successful lawyer). Then in 1873, he had planned to travel to Europe with his family on the S.S. Ville du Havre, but sent the family ahead while he was delayed on business concerning zoning problems following the Great Chicago Fire. While crossing the Atlantic, the ship sank rapidly after a collision with a sailing ship, the Loch Earn, and all four of Spafford's daughters died.'
It Is Well With My Soul.
When peace like a river,
attendeth my way,
When sorrows like sea billows roll;
Whatever my lot,
Thou hast taught me to say,
It is well, it is well, with my soul.
Refrain:
It is well, with my soul,
It is well, with my soul,
Let this blest assurance control,
That Christ has regarded my helpless estate,
And hath shed His own blood for my soul.'
