If God is in control of everything, can Christians sit back and not bother to evangelise? Or does active evangelism imply that God is not really sovereign at all? In this classic study, J. I. Packer shows how false both these attitudes are. In a careful review of the biblical evidence, he demonstrates how a right understanding of God's sovereignty is not so much a barrier to evangelism as an incentive and powerful support for it. "This book is for anyone who is beginning to wrestle with questions of how God's sovereignty can fit with any area of human responsibility. I've often recommended this book to faithful Christians who are confused about how they are to think about prayer, missions, giving - any area in which our efforts could be wrongly pitted against God's own necessary action."? - Mark Dever, Senior Pastor, Capitol Hill Baptist Church, Washington D.C.
