Behold with pleasing extacy. P. Doddridge. [Missions.] This hymn is No. 48 in the D. MSS., and dated "Oct. 30, 1737." It was published in Job Orton's edition of Doddridge's (posthumous) Hymns, 1755, No. 121, in 7 stanzas of 4 lines, in a slightly different form, and entitled “A Nation born in a day; or the rapid progress of the Gospel desired", Is. lxvi. 8, and again in J. D. Humphreys's edition of the same, 1839. In its original form it has not come into common use: but stanzas iv. and v., beginning, "Awake, all conquering arm, awake," very slightly altered, were given in the American Baptist Psalmist, 1813, No. 857. Also in Spurgeon's Our Own Hymn Book, 1866, No. 962.
