From the Wikipedia article on the hymn "It is Well with my Soul" written by Spafford with music by Bliss
This hymn was written after traumatic events in Spafford's life. The first two were the death of his four-year-old son and the Great Chicago Fire of 1871, which ruined him financially (he had been a successful lawyer and had invested significantly in property in the area of Chicago that was extensively damaged by the great fire).[1] His business interests were further hit by the economic downturn of 1873, at which time he had planned to travel to England with his family on the SS Ville du Havre, to help with D. L. Moody's upcoming evangelistic campaigns. In a late change of plan, he sent the family ahead while he was delayed on business concerning zoning problems following the Great Chicago Fire. While crossing the Atlantic Ocean, the ship sank rapidly after a collision with a sea vessel, the Loch Earn, and all four of Spafford's daughters died.[2] His wife Anna survived and sent him the now famous telegram, "Saved alone …". Shortly afterwards, as Spafford traveled to meet his grieving wife, he was inspired to write these words as his ship passed near where his daughters had died.[3] Bliss called his tune Ville du Havre, from the name of the stricken vessel.[4]
This strength to go forward and the words used to express it remind me of the words of Julian of Norwich. I read that this woman, born in the late 1300's, is famous for her statement:
All shall be well, and all shall be well and all manner of thing shall be well.
