Crossing the sea to join his bereaved wife, Spafford was called to the captain’s deck as the ship sailed past the foamy deep where his daughters were lost. The captain informed him that the waters there were three miles deep. Returning to his cabin, Spafford penned these words to the now-famous hymn:
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
Why did such tragedy befall Spafford? He certainly wondered — and wrestled with the question the rest of his life — but in writing this poem, he rested in the sovereignty of God.
