At 27, he experienced a deepening of his faith; and four years later, he quit his teaching job to become an itinerant preacher. He shared God's truths in Great Britain, America, and Japan.
Then, at age 43, he died while serving as a chaplain to the British army in Egypt during WWI.
Everything Chambers taught would have been lost were it not for his wife who took meticulous notes whenever he spoke.
After Oswald's death, Biddy Chambers edited and published over 30 books, My Utmost for His Highest* being the most well-known.
Each of us has important kingdom work to do (Ephesians 2:10) and we'll be rewarded when we do it faithfully whether anyone else knows about it or not.
Few recognize the name of Biddy Chambers, but her act of love has blessed millions of people who've read Chambers truth-filled devotions.
What did God design you to do? Do it faithfully!

This source states: "Oswald Chambers never actually wrote any of his books, although his name is on them. He spoke every word, but it was his wife, and later his daughter, who prepared the manuscripts and mothered each book through the presses."
Other sources state that Chambers proofread "Baffled to Fight Better" before his death. Other sources state he may have authored or co-authored some little known works earlier in his life.
But for all intents and purposes, most of his devotions would have been lost were it not for Biddy.
