The Lord Jehovah calls. P. Doddridge. [Warning to Sinners.] This hymn is No. 64, in the D. MSS. It is in 4 stanzas of 4 lines, and headed, "On hearing God's Voice immediately; from Heb. iii. 13." It has no date; but being found between one hymn dated "April 10, 1735," and another "Jan. 1, 1738," we may date it circa 1736 with tolerable certainty. In Job Orton's posthumous edition of Doddridge's Hymns, &c, 1755, it was given in a slightly different form as No. 309, and with the heading changed to "An immediate Attention to God's Voice required," Heb. iii. 15. The same text and heading were repeated in J. D. Humphreys's edition of Doddridge's Hymns, &c, 1839, No. 335.
