When Mukaa Mbengera Tjivaro received an MP3 player loaded with Bible passages in Himba, she listened to it day and night, driven by a deep thirst she didn’t understand. One day, she approached a visiting pastor to talk about it. The pastor told her about Jesus and she immediately gave her life to Christ.

"Since then," she said, "I have joy in my heart that has never departed from me. I feel that I am one of the luckiest people to have this tool, because it has changed my life."

She has a special box where she has kept the MP3 player safe for the last three years. Whenever she listens to it, she uses what she’s heard to encourage others around her.
