My gracious Lord, I own Thy right. P. Doddridge. [The Service of Christ a delight.] Published by Job Orton in his posthumous edition of Doddridge's Hymns, 1755, No. 294, in 5 stanzas of 4 lines, and headed "Christ's Service the fruit of our Labours on earth:" also given in J. D. Humphreys’s edition of the same, 1839, No. 320. Its use, especially in America, is extensive. Sometimes it is given as “All-gracious Lord, I own Thy right," as in the Unitarian Hymns of The Spirit, Boston, U.S.A., 1864.
