The author of the poem, Annie Johnson Flint, suffered from debilitating arthritis at an early age. She wrote:
When we have exhausted our store of endurance,
When our strength has failed ere the day is half done,
When we reach the end of our hoarded resources,
Our Father's full giving is only begun.
His love has no limit; His grace has no measure.
Hos power has no boundary known unto men;
For out of His infinite riches in Jesus,
He giveth, and giveth, and giveth again.
