Go forth, in spirit go . J. Gambold. [Good Friday.] This appeared in the English Moravian Hymn Book, 1742, in 6 stanzas of 4 lines, the sixth stanza beginning "That heart our Saviour loves." In the 1801 edition this stanza was omitted, and the stanza "His blood thy cause will plead," by John Hartley, was substituted. This form of the text is retained in the 1886 ed. of the same book. In Soden's Universal Hymn Book, 1885, No. 255, stanzas i.-vi. are from the 1742 edition, as above, and stanza vii. is the first stanza of the hymn repeated, with slight alterations.
