Elisabeth Elliot was a young missionary in Ecuador when members of a remote Amazonian indigenous people group killed her husband Jim and his four colleagues. And yet, she stayed in the jungle with her young daughter to minister to the very people who had thrown the spears, demonstrating the power of Christ’s forgiveness.

This courageous, no-nonsense Christian went on to write dozens of books, host a long-running radio show, and speak at conferences all over the world. She was a pillar of coherent, committed faith—a beloved and sometimes controversial icon. And while things in the limelight might have looked golden, her suffering continued refining her in many different and unexpected ways.

Her early years, related in Becoming Elisabeth Elliot, traced the transition of a young woman who dealt in “certainties” to the woman who lived with the unknown.

Now, being Elisabeth Elliot increasingly meant confronting how much she did not understand. She sought her reference point beyond her own experiences, always pondering what she called the “impenetrable mystery” of the interplay between God’s will and human choices.

And it is that strange mystery which shaped the rest of her startling life story.
