Josephine Olsen describes herself as the “Lord’s vessel” for a message of repentance and a call to action for Aotearoa New Zealand. She grew up in the Catholic Church, which remains her spiritual home. At the lowest ebb in her life, she cried out to God – and her prayer was answered. She drew closer to the Lord and spent nine years bringing up four children largely on her own. In 2001 she received the basis of her message "God's call to his people". After discerning it with others, she began sharing it at prayer meetings around New Zealand.

She has written two books based on this message: "God's Call to His People - A Message of Repentance and a Call to Action" and "Cross to Bear - A Walk of Repentance through Aotearoa New Zealand".
