As thy day thy strength shall be. Frances R. Havergal. [Daily Strength.] Written Jan. 1, 1859, and published in the Sunday Magazine, July 1867. It was also inscribed by the author in the Album of her sister (Miss M. V. G. Havergal), and from that has been lithographed in facsimile in Miss M. Havergal's Memorials of her. Miss Havergal's note on the hymn is:—
"The New Year's Bells were ringing in St. Nicholas' Church close to our Rectory (Worcester). I was sleeping with my sister Maria; she roused me to hear them, and quoted the text, ‘As thy days thy strength shall be,' as a New Year's Motto. I did not answer, but presently returned it to her in rhyme (the two first verses, I think). She was pleased, so I finished it the next day and gave it her. The last verse, with a slight alteration, was placed by my cousins on Aunt Izard's tomb, 1868, thus:—
"Now thy days on earth are past,
Christ hath called thee home at last" [Havergal Manuscript]
This hymn is not in common use in Great Britain, but it has been adopted by various American compilers, and is given in Hymns and Songs of Praise, N. Y., 1874, Songs of Christian Praise, N. Y., 1880, &c.
