seeks to begin a critical assessment and appreciation of Abraham’s contributions over the years and explore these contributions in a wide range of fields—mission and evangelism, philosophy of religion, epistemology, and systematic theology, to name a few. The contributors to this volume include scholars and practitioners from different disciplines and ministries. They provide helpful insights into Abraham’s work as well as offer personal reflections on the relational sensibilities that marked Billy as a true friend of the gospel. Their collective insights honor Abraham’s memory, solidify his legacy, and preserve a piece of his rich theological imagination for future generations of the church.
