Lord, I am Thine, but Thou wilt prove. I. Watts. [Psalms xvii.] First published in his Psalms of David, &c, 1719, in 6 stanzas of 4 lines, and headed “The Sinner's Portion and the Saint's Hope; or, The Heaven of separate Souls and the Resurrection." It is given in its original form in the Hymnal Companion and a few other hymnbooks. In addition there are also the following abbreviations in common use:—
1. All, all is vanity below. This is an altered form of stanzas iii.-vi. It appeared in the first edition of Cotterill's Selection, 1810; and is found in several modern collections, including that for the Harrow School Chapel, and others.
2. What sinners value, I resign. This is the most popular form of the hymn, and is in extensive use in Great Britain and America. It appeared in A. M. Toplady's Psalms & Hymns, 1776, No. 154.
