Spafford’s faith was tested on several occasions, first when in 1870 the Spaffords lost their four-year-old only son to scarlet fever and then when they were wiped out financially by the great Chicago fire in 1871. Spafford was a successful lawyer and also a close friend and supporter of D.L. Spafford, It is Well with my Soul” is a hymn of the peace that passes all understanding. Isaiah 66:12 “ For thus saith the LORD, Behold, I will extend peace to her like a river, and the glory of the Gentiles like a flowing stream: then shall ye suck, ye shall be borne upon her sides, and be dandled upon her knees.” It is Well with my SoulĪ beautiful song of faith, written by Horatio G.
