The lyrics to "Hold to God's Unchanging Hand" were written by Jennie Bain Wilson (1857 - ca. 1913); the music was written by Franklin L. Eiland (1860 - 1909). I've been unable to find anything further about the origins, but the hymn has enjoyed popularity for over 100 years, and has been extensively recorded in various styles from bluegrass to blues, gospel to jazz - a Google search brings up 300 results by folk as diverse as The Gaithers, Ry Cooder, Roy Acuff, Rev. Gary Davis, David Grisman, Russ Taff, and Porter Wagoner. It was also a part of the soundtrack to the 2010 movie, True Grit.
Hold to God's Unchanging Hand
Time is filled with swift transition,
Naught of earth unmoved can stand,
Build your hopes on things eternal,
Hold to God’s unchanging hand.
Chorus:
Hold to God’s unchanging hand,
Hold to God’s unchanging hand;
Build your hopes on things eternal,
Hold to God’s unchanging hand.
Trust in Him who will not leave you,
Whatsoever years may bring,
If by earthly friends forsaken
Still more closely to Him cling.
Covet not this world’s vain riches
That so rapidly decay,
Seek to gain the heav’nly treasures,
They will never pass away.
When your journey is completed,
If to God you have been true,
Fair and bright the home in glory
Your enraptured soul will view.
Hold to God's Unchanging Hand
