These papers arose out of the international gathering held in Nairobi, Kenya, which met with the aim of doing “sustained and serious theological and missiological reflection in which children and young people are seen as agents of God’s mission, and lenses through which we find, with the help of the Holy Spirit, new insights into God in Christ.” The hope and expectation was that the conference would “open the way for new streams of theological understanding of church and mission.” There were eight organizations involved; the Child Theology Movement (CTM) was celebrating its 10th birthday; the International Fellowship for Mission as Transformation (INFEMIT) its 35th anniversary; the 4/14 Global Summit looked to Now and Next to deepen its theological and missiological roots, and it was a follow-up to the Lausanne Congress in Cape Town with a specific focus on children.
