It is Well With My Soul- Horatio Gates Spafford
I just want to write a note about this song: the author of this song and his family were going to Europe for vacation. However business kept him back so he boarded his wife and daughters on a boat with the intentions of meeting them later. He received word that the boat had sunk and while his wife survived, all of his daughters did not. He sat down and wrote this hymn. How great a faith.
