In Africa and around the world, the church has been established through the faithful effort of men and women working together for the sake of the gospel. However, failure to acknowledge women’s contributions in evangelism and ministry – or to integrate women’s stories into the history of the church – has led to treating women as secondary within the body of Christ. Women in Mission explores the powerful legacy of women in SIM (formerly, Sudan Interior Mission) and the Evangelical Church Winning All (ECWA), demonstrating that from the beginning women have been active and essential participants in the work of God in Nigeria. Dr. Lami Rikwe Ibrahim Bakari examines various theological and cultural frameworks for understanding the role of women in society before delving into the rich historical reality of women’s involvement in Nigerian church history. This study is a powerful reminder that God’s call to partner in the gospel is not limited by sex, and that it is precisely in recognizing women as primary and active participants in God’s mission – maximizing and not suppressing their giftings –that the kingdom of God is best served.
