Christian mission in the twenty-first century has become the responsibility of a global church. The heart of 'mission' is the drive to cross geographical, cultural and social barriers in order to share the good news of Jesus Christ with all peoples. Drawing on his involvement in missionary work over many years, Samuel Escobar explores how the church spreads the Christian faith. God's Word forms the foundation for his reflections, while he uses insights from theological and historical studies as well as from the social sciences to gain a clearer understanding of the church's missionary calling. His stimulating and challenging analysis contributes significantly to a global evangelical dialogue on mission today and in the future.
