While I was searching for help on the "Do this and live" poem, which I thought possibly by John Bunyan (but evidently not), Wade Kotter informed me of the following hymn by Bunyan.
He that is down needs fear no fall,
he that is low no pride;
he that is humble ever shall
have God to be his guide.
I am content with what I have,
little be it or much;
and, Lord, contentment still I crave,
because thou savest such.
Fullness to such a burden is
that go on pilgrimage;
here little, and hereafter bliss,
is best from age to age.
-- John Bunyan, 1684, from his Pilgrim's Progress
Julian's "A Dictionary of Hymnology" states concerning Bunyan: "This great allegorist cannot be included amongst hymn writers, except on the ground that the piece, 'He that is down needs fear no fall', from pt. ii of his Pilgrim's Progress, 1684, is given in a limited number of hymnals." (1957 Dover reprint ed., p. 193)
