It is Well with My Soul ... one of the most well known hymns written by Horatio Spafford after his lost his family in a tragic storm crossing the Atlantic.
When peace like a river
Attendeth my soul
When sorrows like sea billows roll
Whatever my lot
Thou has taught me to say
It is well, it is well, with my soul
May you be blessed by God's unending love and grace and be filled with hope and peace in your trials.
