Death may dissolve my body now. I. Watts. [Assurance of Heaven.] First published in his Hymns and Sacred Songs, &c., 1707, Bk. i., No. 27, in 6 stanzas of 4 lines, and entitled, "Assurance of Heaven; or, A Saint prepared to die." Its use in its full form, except in America, is limited. In Spurgeon's Our Own Hymn Book., No. 857, "With heavenly weapons I have fought” is composed of stanzas ii.-iv., slightly alteredition The original hymn, with slight alterations in stanza v. only, was included in the draft of the Scottish Translations and Paraphrases, 1745, as No. xxxiii. In the authorized issue of the Translations and Paraphrases, 1781, a recast of the original was given as No. Iv., "My race is run, my warfare's o'er." The alterations were numerous (the first line dating from the Draft of 1751); and in the markings by the eldest daughter of W. Cameron (q.v.) are ascribed to him. It must be designated, Watts, 1707, Sacred Translations & Paraphrases, 1781, W. Cameron.
