'Mission is not the ultimate goal of the church. Worship is. Missions exist because worship doesn't. Worship is ultimate.' John Piper's contemporary classic draws on key biblical texts to demonstrate that worship is the ultimate goal of the church and that proper worship fuels missionary outreach. Piper offers a biblical defence of God's supremacy in all things, providing a sound theological foundation for missions. He examines whether Jesus is the only way to salvation and issues a passionate plea for God-centredness in the missionary enterprise, seeking to define the scope of the task and the means for reaching 'all nations'. Let the Nations Be Glad! is a trusted resource for missionaries, pastors, church leaders, youth workers, seminary students, and all who want to connect their labours to God's global purposes. This third edition has been revised and expanded throughout and includes new material on the 'prosperity gospel'.
