Evangelism and the Sovereignty of God

If God is in control of everything, does that mean that Christians can trust God without striving to evangelize? Or does active human evangelism imply that God is not sovereign in human salvation?

Dr. Packer, Professor of Systematic and Historical Theology at Regent College, demonstrates in this book that both attitudes are false. His careful, incisive, and penetrating study of the Bible teaches us that a correct understanding of God's sovereignty is not an impediment to evangelism but a powerful encouragement and support for it.
