Ah, my dear Lord, Whose changeless love. C. Wesley. [In Temptation.] First published in Hymns and Sacred Poems by J. & C. Wesley, 1739, in 14 stanzas of 4 lines. In Kennedy, 1863, No. 1266, is composed of st. i., ii., iii., vii., x, and xii. In its original form it is unknown to modern hymnals, and the use of this cento is very limited. Stanzas xi.-xiv.—-as "Fondly my foolish heart essays"—-were given in the Wesleyan Hymn Book 1780, as No. 282. The same stanzas are No. 291 of the revised edition, 1875.
