One of the earliest feminist reformers, Butler tirelessly championed the rights of destitute women, opposed human trafficking, and fought for legal equality—transformative work often compared to the legacy of William Wilberforce, though Butler herself is far less remembered.

Williams beautifully uncovers the spiritual depth that fuelled Butler’s activism, showing how her courageous public work was rooted in a profound life of prayer. Butler believed that seasons of waiting, struggle, and apparent failure were decisive in shaping cultural change: “It was persevering in prayer in a time of failure and setback that…turned the tide in the nation.”

Both inspiring and challenging, When Courage Calls invites readers to rediscover a faith that acts—one that steps boldly into the world, grounded in prayer, justice, and the courageous love of Christ.
