It is often said that the Reformed doctrines of election and God's covenant with believers and their children discourage or even impede missions and evangelism. Though those claims are erroneous, the reality is that Reformed circles have often inadvertently given them credibility by neglecting evangelism and maintaining a self-focused church culture. But that does not have to be so. In Go Into All the World, Daniel Holstege demonstrates that, far from impeding missions, a proper understanding of the doctrine of God's covenant actually encourages evangelism. Go Into All the World starts from the inner life of the triune God, who sent his Son into the world as the chief missionary, and ends with the final consummation of God's covenant with his people. While waiting for that final day, not only ministers but all Christians are called by the Lord to bear witness of the gospel of Jesus Christ to their neighbors. The task can be difficult and intimidating. But whether you need doctrinal clarity, practical advice, encouragement for personal or church witness, or a combination of these, Go Into All the World will help you grow in your ability and zeal to be a witness of Jesus Christ, according to your gifts and calling in life. Daniel Holstege is the pastor of Wingham Protestant Reformed Church (Wingham, ON). He was a missionary in the Philippines for five years.
