Doing some teaching preparation I was reminded of this great story / quote about William Booth the founder of the Salvation Army.
His son once asked him the secret of his strength. Booth revealed that as a boy he had knelt at a bare table in the schoolroom of a church. There he vowed that “God should have all that there was of William Booth.”
Years later his daughter, Eva, added her perspective: “That wasn’t really his secret. His secret was that he never took it back.“
