In the ”Great Work of God ”of 1858, in Philadelphia, the Rev. Dudley Tyng was the recognized leader. While standing by a piece of farm machinery on his place, the sleeve of his coat became entangled in the gearing. His arm was drawn into the machinery and torn off, and he died soon after. In the prime of his life he was taken away from the direction of that great revival movement. But his dying message to his associates in the work, ”Stand up for Jesus, ”supplied the theme for this hymn. It was written by the Rev. George Duffield, and was read at the close of a sermon which he delivered on the Sunday following the death of his friend. Set to the tune composed by Mr. Webb, this hymn has become famous and useful.
