The doctrine of adoption-God's decision to adopt sinful men and women into his family-stands at the heart of Christianity. In light of this, Christians' efforts to adopt beautifully illustrate the truth of the gospel. In this popular-level and practical manifesto, Russell Moore encourages Christians to adopt children and to help other Christian families to do the same. He shows that adoption is not just about couples who have struggled to have children. Rather, it's about an entire culture within evangelicalism-a culture that sees adoption as part of the Great Commission mandate and as a sign of the gospel itself.
