Our welcome gift to you.
An inspiring book by missionary Carol Rumpf de Castejón.
Unbelievable but True! HIS story tells the story of Carol Rumpf de Castejón and her life with God for over 61 years (and counting!). Carol is a missionary who traveled from the U.S. to Europe to serve God in the 1960s, at the age of 22. First in France and later in Spain.
In HIS story you will find many wonderful, inspiring and funny stories from the life of a missionary. At the same time you read the story of the immeasurable goodness, faithfulness and providence of Jesus Christ. A very encouraging book!
Ingrid Bijl had the privilege of helping Carol put her story into a digital book to make it available to all.
“It has been a privilege to hear Carol’s stories firsthand and to work with her to make HIS story available to you. Her wisdom and love for Jesus are a constant encouragement and blessing to me.”

Unbelievable but True! HIS story is available as an online book and a pdf file. At the moment the book is only available in English, but we’re looking for opportunities to translate it into more languages.
