"The biblical doctrine of adoption is sadly neglected in much of today's Christian reflection. Dr. Hartman understands--theologically and personally--the importance of this doctrine to the church's life and witness. He provides an accessible survey of the Scripture's teaching on adoption and calls the church to think carefully about what it means to live in light of that teaching. His accounts of his own experiences with biological adoption both round out and commend this work, both to fellow travelers and to newcomers to these issues. May this work help you better to grasp what it means to be and to live as a "son of the living God."-Guy Waters, MDiv, PhD, associate professor of New Testament, Reformed Theological Seminary "Aaron places a human side on God's doctrine of adoption. There is no greater love than sacrificial love, and adoptive love is an act of sacrifice toward one in need of a loving father. Aaron is able to make that kind of love very clear as an adopting father."-Roberto Pena, founder and president, Seeds of Hope Brazil "This book has implications that could radically alter modern American culture! The theology is airtight and the perspective is poignant, clear, and so very personal. This is one book the church at large needs to begin to live out."-Greg Dumas, lead pastor, The Crossing Church, Tampa, Florida "To expound on the theology of adoption with any authority, you need the wisdom of one who has carefully studied the subject from God's perspective and then been moved by the Gospel to practice it. Aaron takes us through the whole of scripture on the subject of our adoption into God's family and blends it with his own story of adopting. The reader is not spared the heartbreak that he and his wife Becky have experienced in adopting. Joy triumphs over sorrow. Compassionate. Loving. Well written. This is theology with boots on!"-Mike Minter, teaching pastor, Reston Bible Church
