Listen for the Donkey Bells;

Listen for the Donkey Bells is a personal memoir by missionary Mabel Sheldon Recorded and Transcribed by her friend Barbara Hulse.
Go to a remote, backward area of the world where the gospel has not been preached. Work hard among a poor and often illiterate people. Watch while some come to Christ and start growing in their understanding of God’s Word, and in their desire to serve the Lord.
Listen for the Donkey Bells is the story of Mabel Sheldon, a missionary who did just that in the "interior" parts of Brazil during the last half of the 20th century. 
Biographies of Christians have always provided challenge and encouragement to readers. They reveal how God takes imperfect servants and works through them to accomplish His purposes. You will see that God used the growing-up years to prepare Mabel for the many difficult situations that she would face in Brazil. You will also learn something of Brazilian culture in the "interior" parts of Brazil during the last half of the 20th century.
May Mabel's story challenge you to faithfully serve our Lord and Savior wherever He has placed you.
