1 As thy day thy strength shall be
This should be enough for thee;
He who knows thy frame will spare
Burdens more than thou canst bear.
2 When thy days are veiled in night,
Christ shall give thee heavenly light;
Are they wearisome and long?
Yet in Him thou shalt be strong.
3 Cold and wintry though they prove,
Thine the sunshine of His love;
If with fervid heat opprest,
In His shadow thou shalt rest.
4 When thy days on earth are past,
Christ shall call thee home at last,
His redeeming love to praise,
Who hath strengthened all thy days.

"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. -- John Julian, Dictionary of Hymnology (1907)
