In some hymnals, the editors noted that a hymn's author is unknown to them, and so this artificial "person" entry is used to reflect that fact. Obviously, the hymns attributed to "Author Unknown" "Unknown" or "Anonymous" could have been written by many people over a span of many centuries. Go to person page >
If you but trust in God to guide you
and place your confidence in him,
you'll find him always there beside you
to give you hope and strength within;
for those who trust God's changeless love
build on the rock that will not move.
